BMW spare parts: Fix-A-Dent Auto Body: Cold forging, dispersal, editing, straightening

At forging preparation in an external part of a bend is extended, and with internal — is compressed and flattened. On behr bmw parts and flattening all methods applied to formation of metal without removal of a shaving are based. Many metals in a cold condition soft and ковкие, for example gold, silver, copper, a brass, tin and aluminium. These metals behr bmw parts at processing by a hammer can be flattened out to (be extended), not losing the durability.

At forging the cross-section section of preparation decreases, and at a deposit — increases. During time протяжки and deposits owing to numerous blows Fix-A-Dent Auto Body of a hammer metal becomes fragile, and there is a danger of rupture of metal. Therefore from time to time metal warm up and pickle.

Formation soft

Metal considerably will improve as a result of heating. Such hot ковка is a forge work during which time to the heated piece of iron on an anvil powerful blows of a hammer form. Details about dispersal and cold forging are resulted in following subsection.

Hammer and linings (substrate)

Influence of blow of a hammer on metal depends on quality of a substrate and hardness of a hammer

Firm substrate — a firm hammer. If the hammer is firmer than preparation at blow metal disperses in the parties, its cross-section is flattened out, extended also
in a blow place decreases. For example, the metal sheet lays on a firm surface of an anvil and it process a metalwork hammer, боек which also is executed from the tempered steel.

Soft substrate — a firm hammer. If the substrate is softer than a hammer and preparation at blow by a hammer metal is flattened out not in the parties, and in a direction of a soft substrate. It is especially convenient at repair of metal products with Fix-A-Dent Auto Body dents. Thus air under a dent is especially soft lining. At blow by a hammer on a dent — for thin (automobile) steel sheets the hammer from an artificial material varis bmw parts suffices — metal is flattened out in a direction of a soft lining, i.e. Air. In such a way level metal sheets.

By the same principle make разгонку. When a hammer with firm brisk (metalwork, разгонным a hammer) strike on equal sheet of metal on a blow place varis bmw parts there is a deepening if a lining on which preparation lays, soft (for example, the lead plate or wooden брусок). Under the further blows of a hammer the metal sheet in a blow place is extended.

Firm substrate — a soft hammer. If the substrate is firmer than preparation, and the hammer is softer than preparation blows of a hammer it can be flattened parts foe bmw out and extended. Energy of blow partially comes back in a soft hammer.

Such way apply to straightening of the bent metal sheets. While air is under a dent, the metal sheet is exposed разгонке and is parts foe bmw straightened, and after straightening blows cannot deform preparation any more.

Рихтовка and straightening Рихтовка is an elimination of the undesirable deformations which have arisen, for example, at transportation, inept Fix-A-Dent Auto Body storage or at excessive loadings. Such deformations are inevitable at some kinds of metal working,
For example a curvature of metal sheets during welding or at cutting. Рихтовку make mechanically by means of a hammer or by means of clamps and a vice for отгибки, and also thermal way — a flame torches.

The bent metal sheets. Thin sheets of metal are corrected by means of a wooden, rubber or synthetic hammer. Begin with blows on bmw suspension parts the centre, and then move on a diagonal to an angular zone, as is shown in 51. Blows should be uniform and not strained. It is necessary to avoid double blows in the same place.

Metal plates with dents. Such plates stack a dent up on a smooth firm lining and a hammer strike on a dent. To this purpose apply a wooden, rubber or synthetic hammer, as it should be softer some straightened metal to avoid new deformations. Thanks to bmw salvage parts hammer blows occurs разгонка metal and the dent disappears. When the plate contacts lined, blows should be stopped, differently on this place there will be a metal stretching.

On the same method eliminate deformations in convex sheets of metal. More often this method apply to straightening of the damaged bmw replacement parts automobile bodies. As linings use various бойки (support), i.e. Steel Fix-A-Dent Auto Body tools with a firm and convex surface. Them keep one hand under metal sheet, and other hand strike on sheet a hammer.

Other method of straightening consists in that by means of a hammer to strike on metal on a spiral round camber, using thus a bmw replacement parts combination «a firm substrate — a firm hammer» (see above). The further from camber make blows, the they should be stronger. At use of the given method in no event it is impossible to beat a hammer on camber.

Very big cambers in metal sheets are good for eliminating by means of a flame сварочной torches. A zone round camber top warm up also metal here it is extended, that leads усадке metal in a place. The part of preparation which bmw auto parts was extended owing to heating, after cooling starts to be compressed. Thus under the influence of a flame deformation сначале amplifies, but after cooling disappears. For confident use of this method it is necessary to save up some experience.

Рихтовка sheet iron. The bent products the convex party stack on a firm substrate and straighten by means of a hammer. On small products the parts for bmw cars deformed place straighten by means of a vice.

The braided cores clamp in a vice, seize suitable pincers or, for example, bmw replacement parts and straighten preparation. Heating up a bend place, it is possible to facilitate considerably.

BMW spare parts: Fix-A-Dent Auto Body: That it is necessary to know about anticorrosive processing of a body

As is known, any car starts to rust in due course is the fact. Imperfect "know-how", and also anti ice means for roads – salt and sand promote it. To stop corrosion completely it is impossible, and here to reduce it to a minimum – quite. For this purpose parts foe bmw also anticorrosive processing is applied. Corrosion happens three kinds: chemical, electrochemical, and. The Most widespread kind of corrosion bmw suspension parts of the car – electrochemical. Roads which bmw salvage parts during winter time constantly salt, a rain, snow, a condensate varis bmw parts at change of a temperature mode of air – all contains water, in which large quantity
Various substances. The latent cavities of a body – thresholds, to a varis bmw parts cavity of doors where water accumulates, a dirt and salt are most subject to corrosion. To remove drying it it is practically impossible.

At anticorrosive processing of the car it is not necessary to stop on a bmw replacement parts of works, to do all at once is better. Full anticorrosive parts foe bmw processing consists of several kinds of works. Each kind protects a Fix-A-Dent Auto Body certain problem site of the car. Recently for body protection application is extended enough
Special mastics of a dense bmw auto parts consistence which, drying up, remains elastic. The covering from mastic protects a body from abrasive deterioration, preventing corrosion. Mastic put manually, a brush, or spray by means of the equipment.



The difficult moment is behr bmw parts processing of the latent cavities which make by means of dispersion of the protective substance easily getting into inaccessible places. Besides, for corrosion decrease, it is possible to use additional components, for parts for bmw cars example, mudguards or. Thus places of fastenings are necessary for processing
Special structure. It is not necessary to do anticorrosive processing independently so the wrong choice of protection frames or a banal carelessness is possible at work.

Is better to address in the anticorrosive centre with good reputation.

BMW spare parts: Restoration of the form of a body by editing and a Fix-A-Dent Auto Body

The technology of elimination of deformations of a body depends on a kind of a warp and character of deformations of details. Dents in body and plumage panels at which metal after blow will not stretch, level expression or to pull a concave site before giving to it of correct curvature and in need of the subsequent рихтовкой the squeezed out surface more often.
Formed in the panel at the big stretching of metal сamber it is impossible to correct рихтовкой as in the course of its performance the top сamber varis bmw parts can lose stability and move on other party of sheet. This circumstance if to consider, that for elimination сamber it is necessary to besiege surplus of metal, defines a way of its editing.
Elimination of deformations in Body details parts foe bmw. For correction of dents and restoration of the form of surfaces of elements of a body use the manual tool presented to section
The big nomenclature Fix-A-Dent Auto Body hammers assumes application of this or that hammer depending on character of a dent and the surface form. A number of hammers has polished Fix-A-Dent Auto Body a part that allows to reach high cleanliness of editing, and on occasion to make elimination of damages without destruction of a paint and varnish covering.

Anvils and shaped plates serve for support of sheet during correction of a dent by a hammer. The form and the sizes of plates and anvils are executed with the account of most often meeting curvature of details of a body and give the chance to apply them at restoration of various sites of a body.

Levers are intended for correction of various dents. The design of levers and length of some from them provides their application in varis bmw parts remote places through technological windows and apertures in body details.

Form restoration кузовных details with use Fix-A-Dent Auto Body the tool. Editing сamber carry out in cold or нагретом a condition. Elimination сamber > in a cold condition is based on a metal stretching on concentric circles or on radiuses from сamber to the intact part of metal (fig. 6.1). At editing smooth transition behr bmw parts from the highest part parts foe bmw сamber to a surface of the panel surrounding it is formed. For this purpose in a direction from the metal surrounding сamber, to the curved part of a surface put a hammer a consecutive series of blows on a circle. In process of hammer approach to border сamber force of blow reduce. The more there will be a behr bmw parts number of circles on the panel at Fix-A-Dent Auto Body, the transition from сamber to the intact part of metal more smoothly will turn out.

Fig. 6.1. Elimination сamber in panels of a body without heating:
And - sites of the panel with сamber; - the scheme of a direction of blows by a hammer (are specified by arrows); / - сamber: 2 - the panel; 3 - the sites of the panel which are subject to extension рихтовкой by means of a hammer: 4 - curvature of the panel after editing сamber

Editing of the deformed surfaces on a rectilinear site of obverse panels with use of a basic plate and hammer is shown on fig. 6.2, and. Correction of deformations on details with not round surfaces carry out with use киянки and shaped plates or anvils of a special profile (fig. 6.2,). On fig. 6.2, in process parts foe bmw insignificant dents on obverse panels of a body, such as a roof is shown, to a door, a cowl, a luggage carrier cover, wings, etc. Sequence of correction of dents on the details of the body having the rounded off obverse surface, is presented on fig. 6.2, г

The considerable plastic deformation which is taking place at extension of metal for elimination сamber Fix-A-Dent Auto Body in a cold condition, increases a behr bmw parts true surface of metal on a restored site and worsens its firmness films. As a result corrosion firmness of metal worsens. Therefore editing rough (wavy, small concave surfaces) panels of bodies and plumage carry out without and increases varis bmw parts in the area of metal by means of a basic plate 2 and a special hammer 1 (fig. 6.3), having a notch on a working part. At elimination of dents by the given way metal is not stretched, and the length of the panel 3 is restored to initial forms and the sizes.

To surface restoration Fix-A-Dent Auto Body details in readily available places apply various Fix-A-Dent Auto Body tools according to curvature of a restored profile of a detail, i.e. Taking into account radiuses, transitions of bmw suspension parts various curvature and rigidity edges. On fig. 6.4 variants of use of shaped plates, anvils, оправок and Fix-A-Dent Auto Body a hammer are shown at restoration of a surface of a forward wing of a body in section А-А.

Camber elimination on a surface of a body a method of heating and fast cooling. It is based on use of processes of expansion and усадки metal, at heating and the subsequent cooling. Whereas plasticity кузовной steels at a room temperature insufficiently high, apply its heating. At heating of a soft steel to temperature nearby 800> °С (red colour) it becomes plastic and is easily deformed. There is no necessity to heat up all surface, and it is enough to choose for this purpose some suitable points.

Fig. 6.2. Restoration of the form of details with use Fix-A-Dent Auto Body the tool: and - elimination of deformations on rectilinear sites of obverse panels; - correction of deformations on details with not round surfaces (a dotted line the initial form of an original detail is shown); in - elimination of insignificant dents on obverse panels of a body; г - elimination of dents on the obverse details having the rounded off surface (figures specify sequence of drawing of blows of a hammer)

Heating of metal of camber on a body carry out a coal electrode сварочного the device (fig. 6.5,) or a flame of a gas torch (fig. 6.5,). The source of heating Most convenient for this purpose is the oxygen-acetylene torch № 0.

At heating of a point of metal by a narrow flame of an oxygen-acetylene behr bmw parts torch the small circle of metal is quickly warmed up until red and plasticity of metal thus sharply increases. As with expansion bmw suspension parts metal interferes less нагретый surrounding metal the increase in its volume occurs at the expense of a thickening. As soon as metal will be warmed up until red, the torch is taken away, and cooling begins: нагретый the metal circle becomes dark red, black and continues to be cooled further.

At cooling metal is compressed, its volume decreases, but the length nor which width did not change is kept by the cold metal located around, neither. As metal has the temperature mismatching the maximum plasticity, that, being bmw suspension parts compressed, it absorbs a small part of lengthening of surrounding metal. Process strengthening осаживания metal make reduction of speed of distribution of heat by ring creation around нагретой parts of metal from a wet fabric, counteraction varis bmw parts of deformation by pressing metal the handle of a hammer or a pipe close нагретой points, percussion of borders of a point of metal, нагретого until red, and then and most points or Fix-A-Dent Auto Body a hammer.

And - metal heating by a coal electrode bmw suspension parts the device: - heating of metal by a flame of a gas torch; in - sequence of cooling нагретой surfaces of a body with camber

Sharp cooling нагретого a body site carry out a tampon of an asbestine mix or a fabric moistened with water. Metal cooling leads necessary a deposit and to acceptance by a surface of a body of a demanded profile. At elimination of camber of a surface of a body by the given method it is necessary to adhere to the sequence of cooling specified in fig. 6.5, century

Elimination of camber-dent by a method of heating and metal sedimentation by shock influence. At рихтовке heating and percussion quickly bring a torch to the camber centre, warm up it and take away a torch as soon as parts foe bmw until red the stain will reach diameter bmw salvage parts no more than 10 mm at a thickness of metal of the panel of 0,6 0,8 mm. At heating it is necessary to watch, that metal has not behr bmw parts begun плавиться. If work carry out alone a torch put aside, and under sheet place a manual anvil almost under defect. Quickly tap not reddened metal around нагретой points, and then нагретую a point while metal still remains dark red. It is preferable to perform this work hammer.

At Fix-A-Dent Auto Body a hammer-gladilkoj force of blow should be small not to create a stretching of metal instead of усаживания. If camber small, enough one point. Work consider finished only when varis bmw parts metal will cool down to an ambient temperature. To cooling acceleration apply the fabric moistened in water. If it is necessary to carry out additional dot heatings it is necessary to do them no more than two, three between each cooling.

After cooling нагретого sheet spend thin Fix-A-Dent Auto Body tempo a site to level a surface of metal which had before deformation.

For elimination of extensive camber (dent) of a surface of a body metal preliminary heat up (fig. 6.6,) in a place of prospective blow. Sedimentation of extensive camber of metal carry out on a basic plate with parts foe bmw the help hammer bmw salvage parts (fig. 6.6,), and dent elimination - with use of a hammer and a shaped plate (fig. 6.6,). The sequence of preliminary heating and drawing of blows at elimination of extensive cambers (dents) depends on the camber form. If camber round points of blows 1-4 have on a spiral in a direction from periphery to the centre and if camber long and narrow points of blows 1-16 have narrow numbers (fig. 6.6,).

Elimination of dents in remote places of a body. Elimination of such dents make by means of levers, basic plates and the special adaptation of shock type.

Correction of dents on obverse surfaces in a zone of an arrangement of amplifiers make by means of the levers which choice depends on bmw replacement parts an arrangement and character of a dent. On fig. 6.7 schemes of editing and examples of correction of elements of bodies with use of levers are resulted. The dents located under amplifiers, eliminate flat levers. and rigidity edges on open sites restore by means of varis bmw parts basic plates and a special chisel. Заломы and dents of panels of doors, and also wings correct levers, using as a support internal elements of panels of a cowl, doors, a mudguard guard etc.

Elimination of deformation of the panel of a threshold (fig. 6.8) make its opening, editing, and welding. On fig. 6.8, and, receptions of opening of a threshold are shown. To opening apply a drill, a drill or an integral vertical drill, a chisel, the lever and a hammer. Editing of the deformed panel of a threshold and restoration of its form make the lever-clip and Fix-A-Dent Auto Body a hammer. the restored bmw replacement parts panel of a threshold carry out a hammer with use of a basic plate as support. In summary carry out welding of the external panel of a threshold with an overlay varis bmw parts and the floor panel

Superficial flat dents sometimes manage to be corrected, not opening the latent cavity. For this purpose in the deepest part of a parts foe bmw dent drill an aperture in diameter of 6 mm through which insert the bent end of a core and extend a concave part of the panel before its normal position. Then an aperture fill with solder or bmw suspension parts

Fig. 6.6. Elimination of extensive cambers (dents) on a surface of a body a heating method in a combination to shock influence: and - metal heating; 6 - camber sedimentation parts foe bmw on a plate; in - elimination of dents by a bmw replacement parts hammer on a shaped plate; г - sequence of heating and metal sedimentation at elimination of cambers (dents)

Elimination of deep dents spend the adaptation of shock type. The adaptation consists of a shock hammer, moving on directing core , bmw auto parts and coming to an end with the handle with a persistent platform. Working body is the complete set of the replaceable tips intended for correction of dents on panels of a body. Replaceable tips connect to an adaptation core a carving.

Quality assurance Fix-A-Dent Auto Body carry out visually or palpation parts foe bmw of a controllable surface by a hand palm. Visually convex or concave parts for bmw cars surfaces by their viewing under a corner or sideways are most easily supervised. To the control of flat surfaces apply rulers. At palpation the slightest roughness is felt as a hand palm.

BMW spare parts: BMW used parts: Repair BMW: If there were problems with coupling

The given way can save to you from 20$ to 100$, but do not forget what to go by this car then to you. BMW replacement parts, it is always better, though and is much more expensive.

Attention! Before something to remove or change I recommend to check up simply level of a brake liquid in a tank. If necessary to add and pump over coupling there is nothing not removing.

Recently has bought BMW 730 E32 and I first with what has faced - unexpectedly for me for the second day of my driving the coupling pedal has started to come back badly, and then and has at all sunk in a floor. Thanks to it I nearly have not caught up «Ме … 600 SEL» trying to return her hand back.

After that I have decided to be engaged in repair. Has put the car in garage and has started to search for malfunction …
Has climbed under the car and has seen varis bmw parts that the working cylinder of coupling all in a brake liquid, and also all surface of a box under it. On cylinder hissing by pressing a coupling pedal it was clear, that cuffs in it has died. Has removed a cover from a bmw used parts flank of a brake liquid together with a float. Has started to remove the working cylinder of coupling - it fastens on two nuts. Bottom turns away easily, and here the top has forced will work - very difficultly подлезть. Having turned off both nuts, I remove the cylinder and I try to turn away a brake tube. After several attempts I have thrown this employment and have decided it not to turn off, it is a little of it to straighten and try to change cuffs directly there.
Having removed the cylinder, has removed from it it can appear too torn and most likely, to it you will not find replacement. It is possible to put and fragmentary (пыльник protects the cylinder from dirt and dust hit), but service life a cuff will be little bit less. Then, a companion on my command has pressed a coupling pedal, and here, the piston with a cuff at me in hands (ATTENTION! Remember as cuffs sat on the piston).
Has started to search cuffs and not having found it in one shop (everywhere suggested to buy the whole cylinder), has gone on the automobile market and has picked up the similar. It has appeared it of cuffs has approached on internal diameter, but was little bit more on external, than native. To select cuffs follows, preliminary having measured the shtangel-compasses. The analogue should have internal diameter little bit less native or same, and external it is, little bit more, on width of special councils is bmw suspension parts not present. The main bmw salvage parts thing - that it normally sat on the piston. But it is not necessary to forget, that native new parts foe bmw it will be always better than any ours.
Taking the piston, a plot of cuffs on it. ATTENTION! To put on cuffs it is necessary correctly - just as the native earlier sat. The most interesting now has begun - it is necessary to insert the piston with a cuff back into the cylinder. For this purpose it is necessary to turn off the union on the cylinder. A screw-driver taking more thin in one hand, a core in another, the beginnings it to insert. A core I press the piston pressing it in the cylinder, and with a screw-driver on the sly I fill cuffs on a circle (to fill better with a stupid subject and it is very cautious not to tear cuffs). Through some attempts of cuffs rises on the place. I put пыльник the cylinder and all the rest into place. And already I twist the cylinder, then the union.
Now it is necessary to pump over only coupling until the pedal of coupling will not start to work as it is necessary, and from the union the made foam liquid or simply air will not cease to go. Prorolling procedure is carried out also as on any our car - one swings time six-seven, to press it is necessary quickly, to return (probably at first a hand) it is necessary slowly, then holds a pedal. The second person from below turns off the union on one-two turn, lowers a liquid and again twists the union. The third person adds at this time a brake liquid in a tank (ATTENTION! Do not regret bmw replacement parts).
Probably it is necessary to resort to reception of compulsory prorolling at first:
The first person lifts a coupling pedal upwards and after the coupling pedal will appear at the top of the second the person turns off the union, and the first at the command of the second, (Protect eyes!) presses a pedal as it is possible more sharply, and keeps it in the pressed condition. After pressing, the strong stream of air with splashes bmw auto parts will be pulled out from the union then we twist the union, we lift a pedal, we add a liquid in a tank (I do not advise to add a brake liquid flowed out of the union). This reception can be repeated until in a coupling pedal not to appear elasticity.
After all done all should work normally.

There is a by-effect: during the first 10 – 100 kilometres the pedal can become again soft and fails (by sharp pressing all should work normally) a little. It though and is unpleasant, but it is not terrible - there is a grinding in a cuff.

Further all should be normal.

The given way is tested on 730 – E32 and 316 – E21.
In theories, this way should approach for any BMW.

BMW spare parts: BMW used parts: Repair BMW: All truth about shock-absorbers BMW.

Shock-absorbers on the design happen:

- The two-trumpet hydraulic

- One-trumpet gas hydraulic with high pressure gas

- Two-trumpet gas hydraulic with gas of low pressure
And - air under atmospheric pressure- gas. In - oil

Difference between 1 and 3 that at the second the space between cylinders is filled by gas under rather small pressure.

What for gas? - Basically, the design 2 has the big resistance to foaming that allows to receive stable enough characteristics in all range of temperatures and suspension bracket courses. But....

With reference to operation, namely to suspension bracket operating modes on real road, this stability is not always necessary. For comfort, controllability, Road holding is important there are transitive modes where, for example, the pure hydraulics, foaming, will bmw replacement parts provide to the shock-absorber necessary rigidity and characteristics in this mode. Therefore when there is a question: gas or hydraulics - a question is incorrect. All depends that that offers, or other firm for the concrete car, and than she explains it. And when one and firm on the same car offers shock-absorbers DIFFERENT in a design anything it not motivating - I DO NOT TRUST! And I conduct thought to one: not very well what shock-absorber on a design, is important the manufacturer, its reputation and quality of production. And these components define both the price, and durability of shock-absorbers, and sensations from driving.

For example, it seems reasonable approach KONI, shock-absorbers letting out two series: KONI Sport and KONI Special - the client should not excite, what at it a design of shock-absorbers gas/hydraulics is offered to it on a choice: for comfortable driving Special, for active Sport. And in both series there are all three constructive schemes. Though are more used on off-road cars and heavy cars.

Personal Charts of shock-absorbers for road application (for pure sports - in another way. Since here all already depends on ambitions and the prices) I Wish to notice also, that the shock-absorbers standing in a series by enough mass cars, make some other sector of the market. As a rule, shock-absorbers Bilstein in a series on BMW are purely hydraulic and have smaller ходимость, than Bilstein Sport, on it.

KONI and Bilstein

At once I will make a reservation why these firms have divided 1-2 places: at one it is better shock-absorbers on one cars, at others on others. If in conversation bmw salvage parts with representatives you mention other firm (Monroe, Boge, Kayaba) - fastidiously screw up the face (these to us not competitors), at the mention of someone from them (KONI or Bilstein), strain, speak, what yes supposedly quite good shock-absorbers, but than them will be better.

These shock-absorbers the most expensive. But also quality at height (die, as a rule, together with the car).

The approach to manufacture:

KONI - to make better than that costs by the car initially (from factory). Supplier FERRARI *, Aston Martin, Mazerati, Lamborghini, Lotus Elize, Dodge Viper, Porsche 968 (if remember such car)

Advantage - possibility of adjustment of rigidity both for deterioration indemnification, and for "прохватить" with adjustment without removal though as shows experience to regulate Special it is necessary through 30... 40 thousand in km. Are made KONI in small amounts. Culture of manufacture at height: each shock-absorber before packing in a box passes test for accurate conformity to the set characteristics (though than more cheaply the shock-absorber is more supposed by that an error in characteristics, and in Germany on them give the LIFELONG guarantee on one car at one owner.

Are issued:

KONI Special (red colour) - for comfortable driving. I.e. at installation of these shock-absorbers at the car smoothness of a course lost-free (I underline lost-free) for controllability (however, controllability it becomes frequent even better) improves

KONI Sport (yellow colour) - for aggressive, energetic driving (For the majority of cars these shock-absorbers have possibility of adjustment of effort of a release without removal from the car). Comfort on them it is essential less than on Special, but the car excellent and allows to increase speed of passage of turns essentially.

KONI Sport kit - the complete set of the truncated springs and the shock-absorbers calculated on application with short springs

KONI Load-a-Juster - the shock-absorber with the spring wound on it with the progressive characteristic that allows to avoid bmw auto parts the car at the big loading (a variant for summer residents).

Bilstein - to make in own way. I mean German Bilstein, yellow color of a series Sports, instead of the Standard dark blue, Spanish (quality it is weak) Distinctive line of these shock-absorbers, that they practically all. At Bilstein accurate orientation to the uncompromising approach - Sports mean rigidly. If on Horses Sport shakes not so, on these з (especially if a forward cartridge - double-dealing fellow McPherson) the real (own sensations from trips on Е34).

The supplier: CHEVY Corvette LT, BMW (partially, and basically hydraulics - that you you will not make for the sake of profit), Porsche Boxter, MB, Ferrari *.

Quality of assemblage too at height. "Yellow" Bilstein serves longer the car (even suffices on one race in the presence of corresponding springs)

Are issued:

Bilstein Sport - sports shock-absorbers (not for sports, and for road application)

Bilstein Sprint - too most, as Sport, but calculated on the truncated springs

Bilstein Rally - for sports application.

Suspension bracket complete sets (springs and shock-absorbers of series Sprint)

Bilstein Standard - blue colour made in Spain. Near to present Bilstein I would not put it - not Bilstein it (there is it in 1.5. 2 times are cheaper than German, quality is worse).

* Originally Ferrari left factory exclusively on shock-absorbers KONI, then, since 1996, supplier Ferrari became Bilstein (it has appeared is cheaper), and now the most part of cars descends on SACHS though adults Ferrari still go on KONI.

BOGE

The German firm making shock-absorbers on the conveyor of many German factories AUDI, VW, BMW, VOLVO, AlfaRromeo. Now belongs SACHSу. Sound shock-absorbers, no more that.

Manufacture principle: to make, let will be. They cheap, but they change characteristics of a suspension bracket of foreign cars not especially considerably, except, perhaps, "oak" series TURBOGAS

Are issued:

BOGE Pro-gas - the gas shock-absorber (with gas of low pressure), is intended for comfortable руления (for this purpose has special проточку in a zone of small courses of the shock-absorber so Monroe Sensa-Trac at all the first "the shock-absorber of new generation"

BOGE Turbo-gas - as something follows from the name aggressive, for sports driving.

BOGE Automatic - anything I can not tell, i.e. the scope of these shock-absorbers is not defined, only the general words

BOGE Nivomat - the special shock-absorber, for fans to carry помногу. In my opinion even possesses possibility to support the set road gleam without dependence from loading.

BOGE Turbo24 - one-trumpet heavy duty the shock-absorber for fans off-road and 4x4.

SACHS

Is hardly worse than BOGE, even more cheaply, are even less reliable. The approach - unification, дешивизна. On "Field" and "Classics" the same shock-absorber under the catalogue - the disorder... (For example, at KONI and Bilstein shock-absorbers different not only under numbers, but also on a design, and on rigidity, that, basically, is correct - after all one car road, and the second a jeep).

The supplier: SAAB, VW, BMW, Audi, Volvo.

Are issued:

SACHS Touring (gas of low pressure)

SACHS???? (I do not remember as the hydraulics is called)

SACHS Sporting Set - for fans of active driving, cheap enough complete set of springs with shock-absorbers.

SACHS??????? (Violet) violet colour - for sports application. KYB, Tokico

The Japanese cheap shock-absorbers. In a series on all Japanese. Rather unreliable (quality - as the random-number generator - where on 300 thousand go and repair BMW where within a month come to an end) it is especially weak the rod at hit on it of the Moscow salt porridge rusts within a week.

Gas, hydraulics and "the strengthened gas" are issued

Very much I liked their decision for Lexus - a combination of one-trumpet and two-trumpet shock-absorbers in one. The truth I do not know whose it there was an idea: Toyota or KYB.

MONROE

The approach one - aftermarket. The shock-absorber has come to an end, has gone has bought cheap but good. Reliability on the average as in advertising - 20000 km. Concerning them "the Newest working out" (see also BOGE which it is valid the first have introduced проточку in the shock-absorber) psychic-trak. If attentively to look at that place where at it проточка involuntarily you reflect: and whether it is correct is made?

It agree, on a cobble-stone, a suspension bracket course small, speeds of moving of a rod of the shock-absorber big, for the best overflowing we will make there проточку. Well, comfortably, softly. We go further. We pawn turn and, the car falls as the American 80х years. What is it? And this oil, free flowing through проточку has not provided the necessary clearing of a list. (BTW and KONI and Bilstein rest to receive the maximum gain of effort of resistance of the shock-absorber at a small gain of speed on speeds of moving of a rod to 0.33m/with, that provides to the car the best course stability and more predicted behaviour in turn (the car falls more slowly))

Are made Monroe:

Radial-matic - Pure hydraulics

Gas-Matic - Two-trumpet gas hydraulic

Van-Magnum - For off-road cars, in my opinion

Sensa-Trac - Two-trumpet gas hydraulic (basically)

I wish to note break of Monroe on the market of suppliers of original shock-absorbers: since 1996 the company delivers parts foe bmw shock-absorbers for some motor-car manufacturers: VAG, Volvo and even PORSCHE. And also their gradual steps to a market direction of "Elite shock-absorbers".

At installation of all these shock-absorbers in a suspension bracket Soviet авто, the difference is felt in comparison with the standard always. And with foreign cars in another way.

KYB, Texico, Monroe to understanding people usually do not like. BOGE and SACHAS so-so, and from KONI and Bilstein only positive emotions (except turned McPhersonов at Bilstein - but it on the fan)

My opinions, by the way, strongly coincide with opinion of Germans which are the basic consumers bmw suspension parts (70 % of sales from the general sale). But they prefer to put all this economy (as, however, and disks with rubber) on new авто to send on errands with all the heart. Therefore there almost bmw used parts nobody goes by Monroe, and basically come across KONI, Bilstein, plus of a combination from these shock-absorbers with springs Eibach, H&R, is simple suspension bracket complete sets

Naturally, there is a question on expediency of installation of those or other shock-absorbers - but it is all a question of money.

If авто - the dying foreign car which to crawl not long remains, on it KONI and Bilstein to put is obviously inexpedient, though enthusiasts come across. If the car only is bought also the person prefers not to potter with shock-absorbers further, to take pleasure in driving then obviously it is necessary to pay attention to positions 1 and 2 charts.

Principal causes of failure of shock-absorbers.

1 Incorrect installation. Pretty often. Forget to tighten a nut, put demountable cups head over heels, forget пыльники, catch at a rod пассатижами, etc.
2 Broken in a smoke or absent pylniki/chippers - rusts / the rod is lifted up and, as consequence, the epiploon comes to an end
3 Weariness of an epiploon (though heard from one mechanic - it Bilstein, brought during stagnant times has gone through 3 cars (!!!!) and till now serves.
4 Breakdown (when levers in knot)
5 Deterioration behr bmw parts systems (does not flow, on hands resistance is, and the car swings)

Still I have not mentioned such firms as DeCarbon (by the way the first "double-dealing fellow" McPherson has thought up) now on a root is bought AC Delco quality there were disgusting, characteristics too.

GABRIEL (the American cheap stuff - comes to an end for a week, road does not hold).

Crosno (the Polish went I know, but I doubt, that is healthy)
