4.1.5. Adjustment of gaps of valves

GENERAL INFORMATION

Adjustment of gaps of valves is necessary for making on the engine, heated-up to normal working temperature. If adjustment of gaps of valves is carried out after major maintenance on the cold engine, it is necessary to make repeated adjustment of valves after engine installation in the car and its warming up to normal working temperature.

PERFORMANCE ORDER
1. Remove the air filter.
2. Mark and remove from spark plugs high-voltage wires.
3. Disconnect a hose of ventilation of a case from a cover of a head of the block of cylinders.
4. Unscrew four bolts and uncover heads of the block of cylinders.
5. For a bolt of fastening of a pulley of a cranked shaft turn a cranked shaft of the engine in such situation that the piston of the first cylinder was in the top dead point in a compression step. It can be checked, having unscrewed a spark plug of the first cylinder and having closed an opening for a candle a finger.
6. At approach of the piston of the first cylinder to VMT in a step of compression the finger will feel pressure. Also it can be checked, having uncovered the distributor of ignition and having checked an arrangement of a rotor of the distributor of ignition. The rotor should be directed on contact of a high-voltage wire of the first cylinder on a cover. Also thus the label on a pulley of a cranked shaft should be combined with the index on a cover (it is shown by an arrow).
7. At engine installation in this situation it is possible to adjust klapanny gaps on the following valves, considering from a drive of the mechanism of a gazoraspredeleniye: the 1st – final, the 2nd – inlet, the 3rd – inlet, the 5th – final.
8. Turn a cranked shaft of the engine on one complete revolution and adjust klapanny gaps on the following valves: the 4th – final, 6 - й – inlet, the 7th – inlet, the 8th – final.
9. Check of a klapanny gap carry out an edge щупа. For adjustment rotate a lock nut of a yoke before very dense moving of an edge щупа.
10. It is also possible to check and regulate klapanny gaps on the working engine. It is carried out in the same way, but on moving valves. Thus it is necessary to screw in a spark plug of the first cylinder and to establish on it a high-voltage wire. For reduction of a razbryzgivaniye of oil establish a piece of cardboard between pushers of yokes and an end face of a head of the block of cylinders.
11. After adjustment remove all traces of old laying from an interfaced surface of a head of the block of cylinders and, if necessary, replace laying of a cover of a head of the block of cylinders.
12. Establish a cover of a head of the block of cylinders and fix it bolts with washers.
13. Screw in a spark plug, connect to it a high-voltage wire and establish into place a hose of ventilation of a case and the air filter.
