Repair and operation of the car

Check and adjust of slits valvate

The check and the agreement of slits valvate must be done in the cold motor.

ORDER OF REALIZATION

Withdraw a carenagem of windshield (to see the Chief Kuzov). Withdraw the superior support of a compartment of reason (to see the Chief Kuzov). Withdraw the covering of protection of the right wing. Empty the system of cooling (to see the Substitution of Section of Cooling Liquid (CL)). Withdraw a decorative covering of the motor. Withdraw the meeting of the camera of delivery of an air way of entry (to see the Head of the system of provision of Power and production of the carried out gases). Withdraw when they were taken of spark (seen the Check of Section e a substitution of captures of spark). Desconecte to hose better of an electric heater. Remove leaders of cylinders (to see the Chief Dvigatel). Bring the piston of the first cylinder in the provision of VMT (to see the Chief Dvigatel). Through the probe they measure slits valvate between empurradores of valves and cames of the axle. Write when they resulted from measurements and compare them with demands of Specifications of the Chief Nastroyki and regular maintenance of the car. This information is going to be needed besides that in the selection of adjusting lavadores. 1 - Final valves of the right number of cylinders 2 - valves of Entry of the right number of cylinders 3 - valves of Entry of the left number of cylinders 4 - Final valves of the left number of cylinders Become an end in the 240th hail. (You turn 2/3) in the direction of the movement of the pointers of the clock also they execute the measurement of slits valvate. 1 - Final valves of the right number of cylinders 2 - valves of Entry of the right number of cylinders Then become an end in the 240th hail. also check slits of the remained valves. 3 - valves of Entry of the left number of cylinders 4 - Final valves of the left number of cylinders Become an end of inclination of a pulley for which the came of the valve that is subject to the agreement in the distributive one to an end if it was developing for a work edge. There explores an empurrador of the valve risked towards a capture of spark (perpendicular to the axle). Through the adaptation (A) they hold tight out an empurrador, put the adaptation (B) between an empurrador and the axle and withdraw the adaptation (A). Install the adaptation (B) in a small angle in the party nominated by the figures "7" or "9" in the situation. There does not begin the adaptation too deeply not to hold tight a lavador. Take an old man lavador of agreement through the small screwdriver and a magneto, measure his thickness for a micrometer and calculate the thickness again lavador in the next formula: N = T + (E - V) Where: T - Thickness of an old man lavador of agreement; E - Size of the slit valvate measured; V - The necessary size of a slit valvate (to see Specifications of the Chief Nastroyki and regular maintenance of the car); N - The necessary thickness again lavador of agreement. Catch a new thickness of lavador of agreement that there allows to bring more near to as much as possible precisely a slit valvate to the necessary value. The lavadores adjust of 17 sizes standard in the variety of 2.500 for 3.300 mm with a 0,050 mm step are given out. In certain cases the old man lavador removed of an empurrador of a valve can be convenient for the installation in an empurrador other, needing the agreement, the valve, - they do not hurry acquiring lavadores replaceable. Pull out an empurrador, establish in him the new lavador of chosen agreement and one secures of the fairness of the done agreement. Working in a similar way, adjust all the slits valvate. Install all being withdrawn component in the sequence, the return to the removal.
