Removal
PERFORMANCE ORDER
1. Remove covers of heads of cylinders of engines.
2. Establish the piston of 1st cylinder in ВМТ a compression step.
3. A removal order: fixing of a spring of a gear wheel, removal final, then inlet cam-shafts.
4. Combine labels, if necessary tighten a cam-shaft. Have in view of that an external cam-shaft – final. The left and right parts are specified on a car course.
5. Attach an auxiliary gear wheel of a final cam-shaft to the main gear wheel in advance prepared bolt with carving М6 and length 15–20 mm (fig. Fixing of a conducted gear wheel see).

The prevention

Remove cam-shafts keeping their parallelism of a plane of a head of cylinders as the axial backlash is very small also the slightest inclination of a shaft can lead to breakages.


6. Gradually release bolts of covers of a final cam-shaft as it should be the return specified (fig. the Order of a tightening of bolts of covers of a final cam-shaft see).
7. Cautiously remove covers, keeping their horizontal position and get a final cam-shaft.
8. Similarly release bolts of covers of an inlet cam-shaft as it should be the return specified (fig. the Order of a tightening of bolts of covers of an inlet cam-shaft see).
9. Cautiously remove covers and get an inlet cam-shaft.
10. Repeat the same actions for the left head of cylinders.
11. If necessary accurately remove pushers and washers. Store all removed details as their initial installation, in special cash desk.
12. Disassemble a final cam-shaft for what clamp it in a vice with soft sponges for шестигранную a neck.
13. A key with two persistent pins turn an auxiliary gear wheel clockwise (1), then turn away an auxiliary bolt, крепящий the main and auxiliary gear wheel, and cautiously weaken effort, giving the chance to an auxiliary gear wheel to turn counter-clockwise, to a spring outright release.
14. Take a lock ring.
15. Remove a spring washer (1), an auxiliary gear wheel (2) and a spring of an auxiliary gear wheel (3).

Check

The technique of check of cam-shafts and pushers differs nothing from described in subsection 3.1.7 for 4-cylinder engines.

Installation
