3.2.10. Camshafts and pushers


1. Remove a gas-distributing belt. Before removing a belt, turn a cranked shaft approximately on 60 ° back. The probability of contact of valves with pistons thereby decreases.
2. Remove asterisks of camshafts.
3. Weaken and unscrew bolts of covers of bearings of a camshaft of inlet valves. Weaken bolts in turn, on a half of turn at one time. Get bolts and remove covers. For carrying out the correct installation during assembly all covers are numbered.
4. Remove a camshaft of inlet valves.
5. Similarly remove a camshaft of final valves.
6. Take pushers and combine them in the separate numbered boxes.


1. Examine cams and it is necessary to replace necks of bearings of a shaft with existence of wear and damages, if necessary a shaft. Examine shaft bearings in a head of cylinders if they too are worn-out, replace a head of cylinders.
2. Examine pushers on existence of wear and damages. If necessary make replacement.


Places of drawing of hermetic

Put hermetic on the shaded areas (are specified by shooters).

Sequence of a tightening of bolts of covers of bearings of camshafts

1. Grease pushers and openings of pushers with pure engine oil and establish pushers on the places.
2. Check, that the cranked shaft still was turned approximately on 60 ° back.
3. Grease cams and necks of bearings of shaft with pure engine oil. Establish camshafts in a head of cylinders. Establish covers of bearings.
4. Put hermetic N15 03 170 on a surface of a head of cylinders round covers of forward bearings of camshafts and in semicircular cuts in a back part of a head (see fig. Places of drawing of hermetic).
5. Tighten nuts of covers of a camshaft of inlet valves in the specified sequence in stages. Tighten covers very carefully, on a half of turn at one time (see fig. Sequence of a tightening of bolts of covers of bearings of camshafts).
6. Similarly tighten nuts of covers of a camshaft of final valves.
7. Establish new epiploons of shaft.
8. Establish asterisks of shaft and the remained details.
