Adjustment клапанных backlashes should be carried out on the cold engine. |

|
The size of a backlash of the final valve is made on the car lifted over the earth. |
1. Result the engine in position ВМТ of the end of a step of compression of the first cylinder (see Has undressed Reduction of the piston of the first cylinder in position ВМТ).
2. Release a nut and the screw коромысла a drive of the corresponding valve of the first cylinder and take advantage probeовым of a measuring instrument лезвийного type.
3. In case of need make corresponding adjustment by rotation of the adjusting screw коромысла, then tighten a nut коромысла with demanded effort.

|
Enter an edge probeа in parallel face surface of a core of the valve.
|
4. Compare results of measurements to requirements of Specifications.
5. Turn a cranked shaft on two complete revolutions clockwise for repeated reduction of the engine in position ВМТ of the end of a step of compression of the piston of the first cylinder and make sure of correctness of installation клапанного a backlash, in case of need make corresponding updating (see above).
6. Operating in a similar manner, make adjustment of backlashes of valves of the remained cylinders as 3 — 2 — 4, each time turning a cranked shaft on 90 ° clockwise for the purpose of reduction of the corresponding piston in position ВМТ of the end of a step of compression. |
