Preparation of the car for checkup

The general information

The given section is made to help on purpose to the owner of the car properly to be prepared to passage of checkup of a vehicle. Naturally, to make all checks under professional standards it is not obviously possible, however consecutive and full performance described below procedures will allow the owner of the car to reveal defects and the deviations, capable to lead to refusal in survey by the technical commission of traffic police.

At revealing of knot or a component which is on the verge of refusal the owner of the car leaves on the discretion the decision of a question on necessity of entering of corresponding correction. In a basis of such decision the general condition of the car is usually put. If the vehicle is represented to survey purely washed up and well well-groomed, checking can shut eyes to presence of insignificant deviations and deterioration of certain components close to border. At the same time, the technical inspector a skilled eye can always define the careless relation of the owner to the car and consider it as aggravating factor.

It is necessary to consider that given to attention of the reader the list of checks and adjustments is full only at the moment of drawing up of the present Management. The norms accepted in more later time and the requirement could not be considered authors.

Let's notice also that for full and qualitative performance of many from listed below procedures the help of the assistant is required.

The full list of checks can be broken into some groups which will be correct to entitle as follows conditionally:
1. The checks made from a driver's place;
2. The checks which are carried out on the car standing on the earth;
3. The checks spent on the car which wheels are torn off from the earth and are freely turned;
4. The analysis of structure of the fulfilled gases.

The checks made from a driver's place

Lay brake

Foot brake

• Squeeze out a pedal of a foot brake against the stop and make sure that it does not continue to fail slowly to a floor. Otherwise it is necessary to check up condition ГТЦ. Release a pedal, wait for some seconds and again squeeze out it. If appreciable resistance to squeezing arises only when the pedal has fallen almost to a floor, it is necessary to make adjustment or repair of brakes. The soft course of a pedal of a brake speaks about air hit in a hydraulic path. In this case the hydraulic system should be pumped over.

Steering wheel and column

Windscreen and rear-view mirrors

Seats and seat belts

• Forward seats should be reliably fixed on a sled, and their backs - strongly to be fixed in vertical position.

Doors

• Both forward doors should open and be closed free both outside, and from within the car. Latches of locks should fix reliably doors in the closed position.

The checks which are carried out without a separation of wheels from the earth

Identification numbers and car signs

Electric equipment

• Include ignition and check up serviceability of functioning of a horn.

• Check up serviceability of operation windscreen.
• Check up serviceability of functioning of indexes of turns, dimensional fires and licence plate illumination. Lenses and reflectors should be reliably fixed and free from a dirt and damages.
• Check up functioning of head headlights and correctness of adjustment of a direction of their optical axes. Reflectors should not be grown dull, presence of cracks on lenses also is inadmissible.
• Include ignition and check up serviceability of functioning of indexes of turns (including control lamps on the panel of devices) and the alarm system. Inclusion of lateral and back dimensional fires should not influence work of indexes of turns, otherwise it is necessary to check up serviceability of grounding in the back combined lantern.
• Check up serviceability of functioning of a back antifog headlight (headlights) and its control lamp on the panel of devices or in the switch.

Foot brake

Suspension bracket and steering

• Ask the assistant to rotate a steering wheel here and there in a small range - till the moment of the beginning of reaction of operated wheels of the car. Estimate size of a free wheeling of a steering wheel. Excessive люфт specifies in deterioration or easing of hinges of a steering column, муфты connections of a column with the steering mechanism or actually реечной transfers.
• Ask the assistant повращать a steering wheel more strongly in both directions - so that operated wheels have started to turn. At this time try to estimate visually a condition of hinges, draughts and support of a steering drive. On cars with the wheel hydraulic booster check up reliability of fastening and a condition of the steering pump, it drive a belt and connecting hydraulic hoses.
• Make sure of horizontal position of landing of the car and adequacy of a road gleam.

Shock-absorbers

System of release of the fulfilled gases

• Start the engine. Ask the assistant to press to a cut of an exhaust pipe a lump of rags and check up a system path on presence of signs of leaks of gases. Repair or replace defective sections.

The checks which are carried out on the car lifted over the earth

Поддомкратьте the car also establish it on props (at all do not get the last under components of a suspension bracket of the car). Make sure that wheels are completely torn off from the earth, and the steering wheel can turn in a full range (from an emphasis against the stop).

The steering mechanism

• Ask the assistant to turn a steering wheel from an emphasis against the stop. Make sure of smoothness of a course of components of a steering drive. No components, including wheels should adjoin thus to brake hoses, tubes or кузовными elements.

Forward both back suspension brackets and wheel bearings

• Begin with the right forward wheel. Grasp it in points on 3 both at 9 o'clock and sharply pull. Presence люфта speaks about deterioration or easing of a pretightness of the wheel bearing, operation of spherical support and hinges, arms and резинометаллических plugs of fastening of components of a suspension bracket.

• Repeat all listed above check for the remained wheels of the car.

Springs and shock-absorbers

• Examine suspension bracket racks (at a corresponding complete set) on presence of signs of serious leaks, developments of corrosion and mechanical damages of casings. Also check up reliability of fastening of support of racks.
• If the car is equipped by screw springs, track, that they correctly took places in saddles, were not треснуты, are deformed or damaged by corrosion.
• In case of a suspension bracket on sheet springs (springs) check up serviceability of a condition of springs, reliability of fastening to them of the bridge, and also a condition резинометаллических plugs анкерных support and earrings of springs.
• the Same checks concern and the cars equipped with other types of a suspension bracket, such as a suspension bracket on торсионных bars, hydraulic дисплейсерах, etc. Check up durability of fastening of all support and arms. Make sure of absence of signs of excessive deterioration, development of corrosion and mechanical damages. On suspension brackets of active type examine hydraulic tubes on presence of signs of leaks and damages.
• Check up shock-absorbers on presence of traces of serious leaks. Estimate degree of deterioration of plugs of support, examine cases of shock-absorbers on presence of signs of mechanical damages.

Power shafts (only for front-wheel cars)

Brake system

• Check up a condition of all rigid brake lines and flexible hoses in a back part of the car. Pay attention to corrosion traces, fastening weakening штуцерных of connections, attritions, swellings (under pressure), cracks cuts and signs of ageing of a material.
• Check up on presence of signs of leaks supports and boards of brake mechanisms. Repair or replace defective components.
• Slowly rotating serially each of wheels, ask the assistant to squeeze out and release a pedal of a foot brake at this time. Make sure of serviceability of operation of brake mechanisms and that the wheel freely rotates at release pedals.

• to Check up efficiency of functioning of brake system without the special equipment it is not obviously possible, however it is necessary to make small trial runs of the car, checking serviceability of its braking lost-free course stability.

The power supply system and release of the fulfilled gases

• Check up a petrol tank condition (including a jellied mouth), fuel tubes, hoses and them штуцерных connections. All components should be reliably attached and free from damages and signs of leaks.

Wheels and tyres

• Attentively examine lateral walls and protectors of tyres of all wheels of the car, including the spare. Check tyres on presence of cuts, swellings, exposures of a cord, traces отслоения a protector and its non-uniform deterioration. Make sure of correctness of landing of tyres on rims of disks. Check up a condition and correctness of landing of gates of a rating.
• Make sure that the wheels established on the car on a standard size correspond to a class and vehicle model (Specifications to the Head Routine maintenance see). On both wheels of each of car axes tyres of one standard size should be established.

Body corrosion

• Check up bearing elements of a body and a car frame (including box-shaped sections of the chassis, thresholds, cross-section beams, racks, and also reference points of components of a suspension bracket, a steering drive and brake mechanisms) on presence of traces of development of corrosion. Истончение bearing elements it is fraught with emergency creation on road. Performance of repair with attraction of experts in that case is required.
• Try to clean all sharp закраины and the agnails which have appeared on кузовных elements as a result of damage by their corrosion.

Check of a condition of the fulfilled gases

Petrol models

• Warm up the engine to normal working temperature and make sure of correctness of all its options (as it should be there should be also all accompanying knots and systems: ignition system, an air cleaner etc.).
• Lift frequency of rotation of the engine to 2500 rpm and keep it on this value within nearby 20 seconds, then again dump turns to single and check up an exhaust condition. If single turns are obviously excessively high, or the exhaust pipe within more than 5 seconds leaves well appreciable smoke of dark blue colour, it is impossible to consider the car ready to checkup passage. The dark blue smoke on an exhaust is a sign of burning out of oil owing to internal deterioration of the engine whereas black testifies to incompleteness of combustion of fuel as a result of pollution of the air filter or other infringements in the power supply system.
• By means of a gas analyzer maintenance level in the fulfilled gases монооксида carbon (WITH) and hydrocarbonic connections can be defined. In case of need it is necessary to hire a gas analyzer.

Check of level of the maintenance in the fulfilled gases монооксида carbon (WITH)

• At the moment of drawing up of the present Management admissible level of the maintenance WITH at single turns of the engine made 3.5 % for the cars which have arrived in operation since August of 1986 and 4.5 % for older cars. Since January, 1996 in Europe more strict norms for the cars, equipped catalytic by the converter and started to be maintained since August 1992 (about 0.5 %) have been accepted. If to achieve hit of level of the maintenance WITH in norm it is not possible (under condition of correctness of options of the engine, power supply systems, ignition etc.) the reason lies in excessive deterioration of the carburettor, or other refusal in the power supply system. It is not excluded also that has simply failed каталитический the converter (in the presence of it in a complete set).

Check of level of the maintenance in the fulfilled gases of hydrocarbons

• At normal level WITH concentration of hydrocarbons in the fulfilled gases on single turns of the engine should not exceed 1200 particles on one million. At negative result of its given check it is necessary to repeat, having lifted turns of the engine to 2000 in a minute. If now level of the maintenance of hydrocarbons falls below limiting value (1200 ch/million), it is possible to consider the car ready to checkup passage.
• the Excessive maintenance of hydrocarbons in the fulfilled gases of the car says about burning out of impellent oil, or that is more probable, about incompleteness of combustion of fuel.

Diesel models

• Unique check of a condition of the fulfilled gases of the diesel engine is measurement of intensity of an exhaust. For check it is necessary to lift sharply some times turns to the maximum admissible value for the unloaded engine.

• Excessive intensity of the fulfilled gases in the elementary case can be caused pollution of a filtering element of an air cleaner, otherwise it is necessary to address for the help to experts of car-care centre.
