Repair and car operation

Technology of performance of repair procedures

Observance of all listed below norms and requirements to carrying out of procedures of the general and major repairs of the car and its components will allow to perform all works at high professional level.

Interfaced surfaces and linings

At a partition of the components joined among themselves at all do not hook their screw-driver, mount or any other lever entered between interfaced surfaces. Such practice is fraught with serious damages of details, leaders to development of leaks of working liquids in the near future as a result of infringement of tightness of a joint. If details "have become attached" to each other and do not give in to a partition, обстучите them on perimetre a hammer with soft brisk for the purpose of destruction of a layer of sealing hermetic. It is necessary to notice that such way can appear inefficient in case of presence of directing pins.

If between interfaced surfaces of two components the sealing lining is established, at its assemblage it is necessary to replace without fail. The lining should be established dry if the return especially is not stipulated in the description of procedure of assemblage. Before installation of a new lining carefully smooth out interfaced surfaces of components, completely having removed from them the rests of a material of an old lining, and hermetic traces (if that is applied). For зачистки surfaces use only the tools, not capable to damage metal of which components are made. Minor defects can be removed by means of a file with a small tooth.

Carving apertures clean by means of the special adaptation for procleaning of tubes. If the return especially is not stipulated in the description of procedure of assemblage, do not grease a carving of fixing bolts with any hermetics or greasings.

Before состыковкой components make sure of passableness of apertures of all galleries and маслотоков. For reliability blow their compressed air.

Epiploons

Extraction of epiploons from the landing nests is made by поддевания by their screw-driver with a flat sting or other suitable tool. Alternatively, the pair can be screwed in a face surface of an epiploon саморезов which heads then it will be possible to grasp nippers.

At assemblage replacement of epiploons is made without fail.

Remember that extremely thin sealing sponges of epiploons can be easily damaged. Presence on walls of a landing nest of an epiploon or a pin of a condensed shaft of agnails, задиров and deep scratches leads to fast development of leaks at the expense of damage of sponges of a new epiploon. If restoration of surfaces contacting to an epiploon is not obviously possible by their machining, replacement of the worn out details is made.

Before installation take care of protection of sponges of an epiploon against damage to process of landing by a way обматывания dangerous sites of contact surfaces an adhesive tape or other suitable material. Whenever possible use conic оправками for maintenance of smoothness of landing of epiploons. Before installation necessarily grease epiploon sponges. Between sponges it is necessary to fill a cavity with dense greasing.

If the return especially is not stipulated in the description of assembly procedure, epiploons always should be established by sponges inside (to a condensed cavity).

Zapressovka/zastukivanie an epiploon in a nest it is made with the help оправки in which quality the face head of the suitable size or a piece of a pipe of the corresponding diameter can act. Epiploon landing in a nest is made against the stop it in a casing coat hanger. If a coat hanger is not provided, the epiploon is put заподлицо with a face surface of a casing (if the return especially is not stipulated in the description of procedure of installation).

Fixture and carving apertures

"The become attached" bolts and nuts for simplification of unscrewing and in order to avoid damage before отдаванием should be processed special getting structure. Many mechanics prefer to use for this purpose turpentine which it is convenient to put from the special small canister with a long nouse. After wetting of the "become attached" fixture it is necessary to give to getting structure within several minutes properly to impregnate the oxidised contact layer. Strongly rusted fixture can be cut down a chisel, is cut ножовкой or removed by means of special гайколома.

For a hairpin reversing screw on its end two nuts and законтрите them from each other, having formed similarity of a head of a bolt. Throw an internal nut рожковый with a key and turn out a hairpin as a usual bolt. At cutting of a head of a bolt or обламывании hairpins on assemblage, the rest of a carving part can be drilled or taken by means of a special ex-tractor. The majority of repair trucks can undertake performance of this, also as well as others (for example, restoration of the broken carving in carving apertures) repair procedures.

Before вворачиванием fixture in deaf carving apertures necessarily check, that in the last does not remain any traces of oil or a moisture - increase of hydraulic pressure in an aperture cavity at a bolt tightening can lead to destruction of the case of a component.

To achieve groove combination корончатой a nut with отверстым an aperture under installation шплинта in a bolt/hairpin body tighten a nut with demanded effort (if the last is stipulated in Specifications), then hold on a nut further before combination with an aperture of the nearest groove of a crown. At all do not weaken a nut for combination of apertures!

For updating of effort of a tightening of fixture ослабьте a bolt/nut on a turn quarter, then tighten with demanded effort. Last technique does not concern cases when at last stage the fixture reaches on the corner stipulated in Specifications.

Counternuts and lock washers

All fixture rotating concerning the case of a component, at a tightening should be without fail completed by a washer.

Spring and гроверные washers after отдавания fixture are subject to replacement. The same concerns lock washers with bent tags.

Самоконтрящиеся nuts in noncritical knots can be used repeatedly, under condition of presence of certain resistance at наворачивании. It is necessary to notice that efficiency of functioning контрящего structure in a nut carving considerably decreases in due course, that is why, such fixture will replace more correctly after everyone отдавания.
