Checks of readiness of the car to operation
In the Section everything which are subject to check knots and systems and are listed ways of independent check of their condition and functioning are offered. On the basis of the analysis of results of such checks it is possible to estimate readiness of the car for operation and checkup passing. Naturally, independently carried out checks cannot be compared on accuracy of measurements with professional, in view of lack of the corresponding qualification of the operator and inaccessibility of the special diagnostic equipment. If during carrying out independent checks need of performance of repair or replacement any of components is revealed, address to appropriate sections of the corresponding Heads of the Management for the purpose of obtaining fuller information.
In most cases performance of the forthcoming checks demands participation of the assistant in them.
The checks made from a driver's place
PARKING (MANUAL) BRAKE
Check of functioning of the parking brake is made by complete raising of the lever of its management. Thus it is necessary to make sure that size of a course of the lever (number of clicks of a ratchet), demanded for emergence of feeling of full resistance, 4-6 clicks for models with a back drive and 5-7 - for all-wheel drive models. If this requirement is not carried out, it is necessary to check serviceability of brake mechanisms of back wheels of the car and/or correctness of adjustment of cables of a drive of the parking brake.
Having completely cocked the parking brake, shake the lever of its management here and there (knock on it from sides) - thus the brake should not be released, - wear of a ratchet or a lever doggie otherwise takes place. Release the parking brake and shake the lever here and there for identification of signs of wear of the axial bearing. Check reliability of fastening of the lever and make sure of lack of traces of corrosion of a bearing element of a body in radius of 30 cm round a lever support. If the condition of fixture of the lever does not give in to check from car salon, estimate it later during the checks made under the car.
Make sure that the brake pedal during the squeezing and an otpuskaniye does not publish any sounds, does not show obvious signs of excessive wear of axial plugs, also check a condition of an overlay of a pedal. Make sure of lack of signs of leakages of brake liquid on a pedal, a floor or a rug surface round a pedal, speaking about violation of tightness of sealing cuffs of the main brake cylinder.
Squeeze out a pedal at first slowly, and then quickly, achieving possibility of keeping of steady pressure. Create pressure and make sure that the pedal does not start then to fail slowly to a floor that again would point to problems with the main brake cylinder. Release a pedal, wait some seconds, then again squeeze out it till emergence of firm resistance. Make sure that resistance starts to arise already on the top site of a course of a pedal. If for resistance emergence the pedal is required to be drowned almost to a floor, it indicates violation of adjustment of brake mechanisms. If firm resistance to squeezing of a pedal does not arise at all, i.e. softness of a course of a pedal takes place, it speaks about hit in hydraulic system of air and need of complete pumping of system.
The free wheeling of a pedal should be 3-8 mm. Check serviceability of functioning of the vacuum amplifier of brakes, having squeezed out several times a brake pedal for depression dumping. Then, holding a pedal squeezed out, start the engine. At the moment of engine start resistance to squeezing of a pedal should change to (decrease). If it not so, exists probability of "leakages" of vacuum hoses of the block of the amplifier of brakes or actually its malfunction.
Lobbies and back brake mechanisms are supplied with indicators of wear which publish a metal gnashing sound at car movement with the brake shoes worn out to maximum permissible thickness.
At emergence of this sound it is necessary to replace brake shoes in the service center MITSUBISHI.
STEERING WHEEL AND COLUMN
Check a steering wheel on existence of cracks or weakening of landing of a nave, spokes or a rim. Shake a wheel here and there, then up-down in relation to a column. Make sure of absence люфта wheels on a column which is the certificate of weakening of a nut of fastening of a wheel or wear шлицов in bulk. Continue to shake a wheel as it is described above, but add still easy rotation it to the right-to the left. Make sure of absence excessive люфта a wheel speaking about excessive wear of the top basic bearing of a shaft, the kardanny hinge (ов) or the flexible coupling.
WINDSCREEN AND REAR-VIEW MIRRORS
On a windscreen there should not be cracks and the other damages, capable is appreciable to limit sector of the review of the driver, or screen wipers stirring to work. Existence of the small it is erose, the stones left at blows it is admissible. Any stickers and pendant souvenirs also should not limit the review of the driver.
Rear-view mirrors should be reliably fixed, are not damaged and to give in to adjustment. The door mirror from the passenger party of the car is not subject to an ekzamenovka under condition of serviceability and the existence of possibility of using by a rear-view mirror fixed from the interior of a windscreen.
SEATS AND SEAT BELTS
Given below check treat seat belts both forward, and back seats.
Carefully check structure of a material of seat belts on existence of cuts, signs of strong wiping or material aging. If the belts of inertial type equipped with returnable devices are established, at survey completely extend them from a drum cover.
Clasp and unbutton each of belts, checking serviceability of functioning of mechanisms of locks (both on a zashchelkivaniye, and on opening) and their reliability. If belts of inertial type are established check serviceability of functioning of returnable devices.
Fastenings of seat belts some of knots are inaccessible and at all are not subject to external survey from car salon, in this case check of their condition should be made late at bottom survey. If any of parts of the mechanism of a belt are fixed directly on a forward seat, support of a seat should be reliably screwed on a floor and their condition is subjected to the same check, as described above for support of belts.
Forward seats also should be reliably fixed and not allow spontaneous change of the situation. Backs should be fixed reliably in vertical situation.
STEERING MECHANISM AND SUSPENSION BRACKET
Ask the assistant slightly повращать a steering wheel to the right-to the left in a range till the moments of the beginning of transfer of rotation to operated wheels. Try to estimate thus size of a free wheeling of a steering wheel till the beginning of operation of the steering mechanism. The size of it люфта gives information on degree of wear of hinges of a steering column, wear and reliability of fastening of the coupling of connection of a column with the steering mechanism or unreliability of fastening, wear or violation of adjustment of actually steering mechanism. The free wheeling of a steering wheel should not exceed 40 mm.
Ask the assistant strongly повращать a steering wheel in both directions in a range prior to the beginning of turn of operated wheels. Thus watch closely behavior of hinges, drafts and other elements of a steering drive and knots of their fastening. The components showing signs of wear, damage, deformation or unreliability of fastening should be repaired or replaced. If the car is equipped with system of hydrostrengthening of a wheel, check also reliability of fastening of the pump of system and a condition and correctness of a tension of its driving belt. The system should function and not show regularly signs of leakages of hydraulic liquid or damage of hoses. Additional checks can be made later when the car will be lifted over the earth and access under it considerably will become simpler.
Make sure of flatness of landing of the car and correctness of height of a road gleam. Make sure that there is a sufficient gap between components of a suspension bracket and buffers of a course of the compression, a guaranteeing full speed of a suspension bracket.
Press serially each of car corners, sharply then releasing it. If the shock-absorber as it should be, a corner has to rise, and then return to normal situation. If the car corner after an otpuskaniye continues to be shaken up-down, the shock-absorber lost the dempfiruyushchy properties.
SYSTEM OF PRODUCTION OF THE FULFILLED GASES
Start the engine and, having asked the assistant to press to a cut of an exhaust pipe a rags lump, check all system on existence of signs of the leaks which are showing in the form of rhythmically pulsing streams of a smoke or the hissing sound, proceeding directly from a leak source. Check overall performance of the exhaust silencer, having made sure that level of the sound published at operation of the engine corresponds expected for the car of this type. In case the system generally is in a satisfactory condition, insignificant local leaks can be eliminated by means of a patent special remnabor.
The checks made on the car, lifted over the earth at freely rotating wheels
To Poddomkratta the car, having reliably fixed it on the props got under points bearing loading of a frame of the car. Establish props so that they did not make contact with suspension bracket components (including at a povorachivaniye of forward wheels). Make sure that all wheels do not concern the earth, and operated are capable to turn from an emphasis against the stop.
Check a condition of rubber protective covers of a steering rack. Make sure that on them there are no cuts, signs of leaks and unreliability of fastening of bandages. If management is equipped with hydrostrengthening system, check its rubber hydraulic hoses, tubes and knots of their joining on existence of signs of aging of a material, leaks, protertost and other damages. Attentively see all components of a steering on existence of signs of jamming or too hard course, loss шплинтов and other lock adaptations, and also traces of excessive corrosion of elements of a body in radius of 30 cm round knots of fastening of any of components.
Ask the assistant to turn a steering wheel against the stop at first on the left, then to the right. Make sure that thus steering components (columns, the mechanism and a drive) move smoothly and freely and that any of them (including disks and tires of wheels) does not make contact with hoses or tubes of brake system or any elements of a body of the car.
FORWARD AND BACK SUSPENSION BRACKETS AND BEARINGS OF WHEELS
Since right forward, serially inspect a condition of bearings of wheels, spherical support of a suspension bracket, rotary knots and fixture of components of a suspension bracket. For this purpose undertake a wheel in points on 3 both at 9 o'clock and strongly pull it. Presence of any люфта in the transferred knots is inadmissible. Check cases of rubber and metal plugs of components of a suspension bracket on existence of signs of aging or material damage, and components on existence of bends, deformations and signs of excessive corrosion. Check presence of all шплинтов, lock washers or other kontryashchy equipment of fixture of components of a suspension bracket. Make sure of lack of traces of strong corrosion of elements of a body in radius of 30 cm round points of fastening of components.
Existence of any excessive люфта can be established by an introduction way between a support of a component and its body of mount or a big screw-driver and their use as the lever. Whether thus it is possible to establish is the weak point reason wear of the axial plug, a fixing bolt or actually a time (often there are developed to an oval form boltovy openings).
Now undertake a wheel in points on 12 and at 6 o'clock and repeat the check described above. Povrashchayte a wheel, whether checking there are no zakusyvaniye points in its bearing.
Repeat check for the second forward wheel, and then for both back.
SPRINGS AND SHOCK-ABSORBERS
Check assemblies of amortization racks of a suspension bracket on existence of signs of leakages of liquid, corrosion, deep cavities of rods of pistons or damages of casings. Besides, make sure of reliability of fixture of racks.
Check shock-absorbers on existence of signs of serious leaks (the insignificant socheniye of liquid is the normal phenomenon for shock-absorbers some of types). Check fixture and plugs of basic knots on existence of wear and damage of cases of blocks.
If it is possible, without assorting mechanisms, check a condition of brake shoes and disks. Make sure that the material of frictional slips is not worn-out excessively and that on surfaces of disks there are no cracks, cavities, furrows and other signs of excessive wear.
Attentively check a condition of rigid brake tubes under the bottom of the car and flexible hoses of back brake mechanisms. Existence of traces of excessive corrosion, protertost, unreliability of fastening of shtutserny connections of tubes, and also cracks, signs of aging of a material, leaks and swellings under the pressure of flexible hoses is inadmissible.
Check supports and boards of brake mechanisms on existence of signs of leakages of the brake liquid speaking about violation of quality of hydraulic consolidations of the corresponding components.
Slowly rotating serially each of wheels ask the assistant to squeeze out a foot brake, and then to release it. Make sure thus of serviceability of functioning of each of brake mechanisms, and also that the wheel rotates freely at an otpuskaniye of a pedal of a brake. To check efficiency of operation of brake mechanisms without use of the special equipment it is not obviously possible, however trial runs (in the presence of the corresponding road and weather conditions) are capable to reveal effect of withdrawal of the car aside at rectilinear movement.
Check the mechanism of a drive of the parking brake on an istrepyvaniye and break of cables, excessive wear and unreliability of fastening of drafts. Having asked the assistant to cock, and then to release the parking brake, make sure of reliability of operation and an otpuskaniye of brake mechanisms of each of back wheels of the car.
POWER SUPPLY SYSTEM AND PRODUCTION OF THE FULFILLED GASES
Check a condition of a fuel tank, tubes, hoses and shtutserny connections (including connections on the pump, the filter and carburetor/system of injection of fuel). All components should be reliably fixed and not have signs of leaks. The cover of a fuel tank should be closed reliably to correspond on type shown by manufacturers of the car to requirements.
WHEELS AND TYRES
Attentively look serially tires of all wheels as with external, and from the inside, and also on all surface of a protector. Existence of cuts, cracks, swellings, consolidations, protector stratifications, and also exposures of a cord and a tire framework owing to wear or damages is inadmissible. Make sure of density of landing of a board of the tire on a rim of a disk of a wheel. Check landing and a condition of the valve of a rating of the tire (nipple). Povrashchayte of a wheel, checking disks on existence of signs of deformations, in particular on a rim.
Make sure that the tires of the correct size corresponding on a standard size to make of the car are established. Installation on one axis of tires of different type or is the size inadmissible. Use at normal operation of the car of spare tires of special (compact) type is inadmissible. Besides, tires should be pumped up with demanded pressure.
By means of the special adaptation measure depth of a pattern of a protector of the tire. By the safety rules of traffic accepted now the pattern should be looked through accurately on all area of a protector and have depth not less than 1,6 mm at least on three quarters of width of a protector. A certain wear of a protector on external and internal edges is admissible, however it should have a form of an equal continuous ring and a protector pattern on a worn-out site should be looked through also. Any excessive wear from listed can appear a sign of violation of adjustment of corners of installation of forward wheels which should be checked above before tires will finally fail. More detailed information on typical wear of protectors and adjustment of corners of installation of forward wheels see in the corresponding Heads of the Management.
Check all bearing elements of a body and a car frame on sites subject to loads of existence of signs of corrosion. Loaded and bearing all profile elements of a frame, thresholds, cross-section beams, racks of a body, a support and fixture of elements of a suspension bracket and a steering, components of brake system and seat belts are considered. The corrosion which is essentially reducing thickness of metal of bearing sites of a body of the car and causing their easing is inadmissible. In this case the car should be subjected to body repair.
Check of toxicity of the fulfilled gases
Warm up the engine to normal working temperature and make sure of implementation of preliminary requirements to carrying out check of adjustment of turns and qualities of a mix of idling (i.e. that the ignition system normally functions, and the element of the air filter is in a satisfactory condition).
Before the beginning of measurements lift frequency of rotation of the engine to value approximately in 2500 rpm and hold it at this level about 20 seconds. Again dump turns to single and get accustomed to a smoke leaving an exhaust pipe of the car. If turns of idling are obviously exceeded, or in case of emission from system of release of clearly appreciable dark blue or black smoke during time more than in 5 seconds, it is necessary to subject the car to repair. The dark blue smoke is a sign of burning out of impellent oil (wear of maslootrazhatelny caps of cores of the valves, directing plugs of valves, piston rings or a mirror of cylinders) while black it is possible to consider as the certificate of incomplete combustion of fuel (pollution of an element of the air filter, excessive reenrichment of a mix or other problems in operation of the carburetor or system of injection of fuel).
If turns of idling and an external condition of an exhaust are in norm, it is necessary to measure by means of the analyzer of the fulfilled gases the contents in an exhaust of carbon monoxide (WITH) and hydrocarbonic connections. Further it is supposed that such analyzer can be to hire or is borrowed - to get it for the amateur mechanic irrationally. Alternatively it is necessary to address for carrying out this check on car repair shop where quotations on this type of works are usually quite moderate.
ISSUE WITH (QUALITY OF THE MIX)
At carrying out this check it is necessary to be guided by requirements shown traffic regulations to the contents WITH in exhaust gases.
If to achieve decrease in level of the contents WITH before its hit in admissible limits it is not possible (it is supposed that from other points of view of a power supply system and ignition function regularly), it is necessary to assume existence of strong wear of the carburetor or any defect of system of injection of fuel. On the carburetors equipped with automatic equipment of start probably that an air zaslonka it is not released properly.
The option when level WITH meets requirements of traffic regulations is possible, but exceeds the norm established by manufacturer.
ISSUE OF HYDROCARBONIC CONNECTIONS
Having made sure that level of the content in the fulfilled WITH gases is in norm (or achieve it), pass to measurement of the contents in an exhaust of hydrocarbons. It should not exceed 1200 particles on one million. If the car does not pass this check on single turns, repeat it at frequency of rotation of the engine in 2000 rpm; if now the content of hydrocarbons gets to norm, it is possible to consider check successfully passable.
The excessive content in the fulfilled gases of hydrocarbonic connections can be a sign of burning out of oil, however with not smaller degree of probability can be caused as well by incomplete combustion of fuel. It is possible to include in number of the possible reasons:
a) Bad condition of spark plugs or wrong candle gap.
b) Violation of installation of a corner of an advancing of ignition.
c) Wrong gap of valves.
d) Low kompressionny pressure in cylinders.
Remember also that the excessive content of hydrocarbons in the fulfilled gases can be a consequence of violation of functioning of the catalytic converter (if that enters into a car complete set).
