Pressure check fuel, GENERAL DATA


CARBURETTOR ENGINES

For check of pressure of fuel it is necessary to include a manometre between the fuel pump and a tube of giving of fuel in bmw auto parts the carburettor. It is necessary also to shunt the return fuel valve included in a highway after the fuel pump. The PERFORMANCE ORDER
In the absence of a manometre pressure can be checked up on струе from the hose disconnected from the pump, turning the engine a starter (disconnect also a high-voltage wire from the ignition coil).



INJECTOR ENGINES
The prevention

The fuel filter should be in a satisfactory condition. If the filter is littered, it is necessary to replace it.
On cars with the pump of pumping pressure is measured at work of the basic pump and the pumping pump.

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)

BMW spare parts: Repair of running part BMW

In the general words forward and back suspension brackets of wheels, wheels and tyres enter into concept "a running part of the car". A suspension bracket basic purpose – softening and clearing of the fluctuations transferred from roughnesses of road on a body of the car. About a running part of the BMW legends go. This knot always was famous bmw replacement parts for the quality and reliability. But nothing happens eternal. There is a deterioration of details, such as shock-absorbers, springs, spherical support, the top support to bmw auto parts bearings, draughts and stabilizer support. It is behr bmw parts promoted to no small degree also by driving on bumpy Russian roads. During movement the car starts to jump up, as if a ball, and on abrupt turn there is a characteristic loud crash.

While in service the car malfunction of a suspension bracket of the BMW can be shown differently:
On rough road at turns there is a pulling down of a forward or back axis; 
At journey of joints at asphalt or hollows extraneous knocks are distributed; 
At journey of roughnesses on road there is a body rocking; 
At braking the brake way increases;
At braking on rough road system ABS prematurely works.

If you have noticed one of signs diagnostics and the subsequent repair of suspension bracket BMW, has not varis bmw parts avoided you. Timely diagnostics and repair BMW spent in our car-care centre, will be pledge of your safety. Experts of service BMW will carry out bmw suspension parts computer diagnostics of a running part of your car, using the behr bmw parts advanced equipment and the tool, quickly and will precisely establish malfunctions of a running part and operatively them will eliminate.
Diagnostics of a running part of the BMW provides following operations:
Check of a condition of shock-absorbers, springs and basic cups; 
Absence check люфтов in spherical support and steering tips; 
Condition check, etc. knots of a running part of the BMW; 
Check of serviceability of basic bearings;
Coupling check; 
Check brake , disks, drums, hoses.
By results of diagnostics of running part foe BMW each client receives diagnostics sheet in which it is underlined on hands:
Necessary amount of works and its cost; 
The list of the works, necessary to execute first of all; 
Recommendations about application of bmw salvage parts.

Usually first of all happens it is necessary to execute following kinds of works:
Repair of shock-absorbers BMW; 
Replacement the BMW; 
Replacement and adjustment of basic bearings;
Coupling replacement.

Sometimes it happens quite enough for continuation of safe driving. Do not tighten with arrival to car-care centre BMW, after all from serviceability of all details of the car, safety of driving depends. Repair of suspension bracket BMW – not the most bmw used parts terrible, that can happen, skilled masters will quickly cope with this problem.
