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 lifting of the engine and the sensor of pressure of oil.
3. To remove the vacuum pump, unscrewing consistently (and on an identical corner) two bolts of fastening.
4. To remove covers of bearings No. 2 and 4 of a cam-shaft.
5. To unscrew on 1/4 turns of a nut of other covers of bearings of a cam-shaft.
6. To remove covers of bearings of a cam-shaft together with the top loose leaves, 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 them it was possible to establish in the same nests of a head of the block of cylinders in which they stood earlier.
8. To take a pusher of a drive of the vacuum pump.
9. By means of the adaptation (21.024) to compress springs of separate valves and to remove crackers.
10. To clean the 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 grease with engine oil cores of valves and to insert them into the directing.
2. The ends of cores of valves to wind with a sticky tape in order that they did not damage working edges of caps and by means of the adaptation 21.007 to establish caps on cores of valves.
3. To establish springs of valves, the top plates and by means of the adaptation 21.024 to compress springs and to insert crackers.
4. To grease with engine oil a rod of a drive of the vacuum pump and to insert it into an opening of a head of the block of cylinders.
5. To oil pushers and to establish them together with plates of adjustment of a gap of valves in nests in a head of the block of cylinders in which they were established earlier.
6. To insert into nests in a head of the block of cylinders the bottom loose leaves of bearings of a cam-shaft and to grease them with engine oil.
7. To establish a cam-shaft on loose leaves; the clown on the end of a shaft should be directed up.
8. To establish the top loose leaves in covers of bearings of a cam-shaft and to oil them.
