Removal
PERFORMANCE ORDER
1. Remove covers of heads of cylinders of engines.
2. Establish the piston of the 1st cylinder in VMT of a step of compression.
3. 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. Keep in mind 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 of 15-20 mm (see fig. Fixing of a conducted gear wheel).

Prevention

Remove cam-shafts keeping their parallelism of the plane of a head of cylinders as the axial gap is very small and 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 (see fig. Order of a tightening of bolts of covers of a final cam-shaft).
7. Carefully remove covers, keeping their horizontal situation and get a final cam-shaft.
8. Similarly release bolts of covers of an inlet cam-shaft as it should be the return specified (see fig. Order of a tightening of bolts of covers of an inlet cam-shaft).
9. Carefully 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 a six-sided neck.
13. A natural two persistent pins turn an auxiliary gear wheel clockwise (1), then unscrew the auxiliary bolt, fixing the main and auxiliary gear wheel, and carefully weaken effort, giving the chance to an auxiliary gear wheel to turn counter-clockwise, before spring liberation.
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

PERFORMANCE ORDER

6. Establish a cam-shaft in a head so that 2 dot labels were turned at 3 o'clock (towards a final cam-shaft).
7. Grease basic surfaces of a forward cover with hermetic.
8. Establish covers, having turned arrows towards a belt.
9. Tighten bolts of covers in the specified sequence with the set moment (see fig. Order of a tightening of bolts of covers of an inlet cam-shaft).
10. Establish a new epiploon (see subsection 3.2.9).
