1. Disconnect a negative wire from the battery.
|
If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that have the correct combination for audiosystem input in action! |
2. Uncover heads of cylinders (see. Section Removal and installation of covers of heads of cylinders). 3. On models from RKPP cock the parking brake and choose neutral transfer. 4. Turn out spark plugs (see. Head of Control and routine maintenance). 5. Bring the piston of the first cylinder into the provision VMT of the end of a step of compression, - track correctness of combination of adjusting labels (see. The section Reduction of the piston of the first cylinder in the provision of the top dead point (VMT)). 6. Measure gaps of the corresponding valves. Write down results of measurements and compare them to requirements of Specifications. Mark the valves which gaps fall outside the limits an admissible range.
|
7. Turn a cranked shaft in the normal direction (clockwise) on 240 ° for the purpose of reduction in position VMT of the piston of the third cylinder and measure gaps of valves of the next set. |
|
8. Turn a shaft for 240 ° (VMT of the 5th cylinder) and check gaps of the remained valves. |
9. Having finished measurement, turn a pulley of a cranked shaft so that the cam of a drive of the first of valves subject to adjustment was developed by a working ledge up (from a pusher).
|
10. Develop an adjusting washer an opening to the central part of molding of a head of cylinders. Establish special nippers so that their top sponges covered a shaft at a cam cheek, and bottom rested against washer top. Compress handles of nippers and develop the tool aside from a camshaft, wringing out a pusher. Pass a sting of the second special tool in a gap between edge of a pusher and a camshaft, then release a pusher. For extraction of an adjusting washer it is possible to use tweezers (raise washers a screw-driver) or the magnetized core.
|
Supply of the compressed air in an opening will help with a washer to its extraction. |

11. Measure thickness of the removed washer by means of a micrometer or the calliper equipped with a noniusny scale (see an accompanying illustration). For calculation of thickness of a new washer which should be established on a pusher for the purpose of correction of a klapanny gap it is made on the following formula:
Inlet valves: N= R + (M - 0.30 mm) Final valves N = R + (M - 0.33 mm)
Where:
R-Thickness of an old washer in millimeters M - the Measured klapanny gap in millimeters N-Thickness of a new washer in millimeters |
12. Pick up a new washer, such that its thickness as it is possible closer corresponded to demanded value. Washers of 64 sizes with a step of 0.01 mm to a range from 2.32 mm to 2.95 mm are issued.
|
Removed from a pusher of one valve the washer can be suitable as new for correction of a gap of another, - make the corresponding calculations before will go behind new washers. |
13. Operating in a manner similar described in paragraph 10, serially establish on pushers of the corresponding valves the new picked-up washers. 14. Make sure of correctness of adjustment of klapanny gaps (see above), in case of need make repeated selection of washers. 15. Assembly to a head is made as it should be the return to an order of dismantle of components. |
