3.2.1.4.3. Repair of a head of the block of cylinders

Dismantling

PERFORMANCE ORDER
1. To remove inlet and final collectors.
2. To unscrew from a head of the block of cylinders two brackets with openings for raising of the engine and the oil pressure sensor.
3. To remove the vacuum pump, unscrewing consistently (and on an identical corner) two bolts of fastening.
4. To uncover cam-shaft bearings No. 2 and 4.
5. To unscrew on 1/4 turns of a nut of other covers of bearings of a cam-shaft.
6. To uncover cam-shaft bearings together with the top inserts, sealants and to take a cam-shaft.
7. To take pushers together with plates of regulation of a gap of valves and to arrange so that at assembly they could be established in the same nests of a head of the block of cylinders in which they stood earlier.
8. To take a pusher of the drive of the vacuum pump.
9. By means of adaptation (21.024) to squeeze springs of separate valves and to remove crackers.
10. To remove adaptation and to remove the top basic plates of springs, a spring and the valve.
11. By means of special nippers (MS-1501) to remove maslootrazhatelny caps from cores of valves.

Check

After dismantling of a head of the block of cylinders it is necessary to wash up carefully all details, to check their technical condition and to estimate suitability for further work (see subsection 3.2.1.2.2). It is necessary to replace all laying and to make grinding in of valves.

Assembly

PERFORMANCE ORDER
1. To oil engine cores of valves and to insert them into guides.
