3.3.10. Camshafts and pushers

Removal

PERFORMANCE ORDER
1. Uncover camshafts.
2. Remove asterisks of camshafts. If you remove camshafts of the right head of cylinders, turn them approximately on 60 ° back. Thus, the probability of contact of valves with pistons decreases.
3. Weaken and unscrew bolts of covers of bearings of the camshaft of inlet valves. Weaken bolts in turn, half way at one time. Get bolts and uncover. For carrying out the correct installation during assembly all covers are numbered (it is specified by shooters).
4. Remove the camshaft and an epiploon. Mark the camshaft of inlet valves not to mix it with shaft of final valves.
5. Remove a shaft of final valves.
6. Take pushers and put them in the separate numbered boxes.


Check

PERFORMANCE ORDER
1. Examine cams and necks of bearings of a shaft on existence of wear and damages, if necessary the shaft needs to be replaced. Examine shaft bearings in a head of cylinders. If they are worn-out too – replace a head of cylinders.
2. Examine pushers on existence of wear and damages. If necessary make replacement.

Installation

PERFORMANCE ORDER
1. Grease pushers and openings of pushers with pure engine oil and establish pushers on the places.
2. Grease cams and necks of bearings of shaft with pure engine oil. Install camshafts in a head of cylinders.
3. Temporarily establish asterisks. Tags of asterisks of the left head have to be combined with cover cuts, and tags of asterisks of the right head are turned approximately on 60 ° concerning cuts in a cover back.
4. Apply N15 03 170 sealant on a surface of a head of cylinders around covers of forward bearings of camshafts (it is specified by an arrow).
5. Establish covers of bearings according to their numbers (are specified by shooters).
6. Tighten nuts of covers of the camshaft of final valves in the spiral sequence, since an average cover. Tighten covers very carefully, on a half-turn at one time.
7. Similarly tighten nuts of covers of the camshaft of final valves.
8. Establish new epiploons of shaft.
9. Establish asterisks of shaft and the remained details.
