Check of phase installation of camshafts

Engine 111

Check

 PERFORMANCE ORDER

1. Uncover heads of cylinders, address to appropriate section.
2. Turn a cranked shaft before position of the piston of the first cylinder 25 ± 2 ° after VMT, at the same time cams of the first cylinder of a camshaft of inlet valves should be turned at an angle up.

3. Check phasing of a camshaft of inlet valves. For this purpose check, whether the finger (1) through an opening in a forward cover of a camshaft is inserted into an opening in a camshaft flange. If the finger is not inserted, there are deviations in an angle of rotation of a cranked shaft, if necessary adjust the provision of a camshaft.

The engine with camshaft adjustment: An emphasis located on a circles of an asterisk of a camshaft of inlet valves (2), should be in situation "late" (an emphasis in flange grooves in the direction of rotation of a camshaft) (an arrow above).

At erroneous installation of a chain if, for example, the chain is displaced on one tooth, the angle of rotation of a cranked shaft changes approximately on 20 °.

4. Remove an adjusting finger.
5. Turn a cranked shaft before position of the piston of the first cylinder 28 ± 2 ° after VMT, at the same time cams of the first cylinder of a camshaft of final valves should be turned at an angle up.
6. Check phasing of a camshaft of final valves. For this purpose check, whether the finger (3) through an opening in a forward cover of a camshaft is inserted into an opening in a camshaft flange. If the finger is not inserted, there are deviations in an angle of rotation of a cranked shaft, if necessary adjust the provision of a camshaft.

At erroneous installation of a chain if, for example, the chain is displaced on one tooth, the angle of rotation of a cranked shaft changes approximately on 20 °.

7. Remove an adjusting finger.


Phasing correction

 PERFORMANCE ORDER

1. The cover of a head of cylinders should be removed.
2. Turn a cranked shaft in the direction of rotation of the engine and establish the piston of the first cylinder in situation 20 ° after VMT.
3. Remove a forward cover.
4. Remove a natyazhitel of a chain, address to appropriate section.
5. Remove the top directing.
6. Remove an asterisk of a camshaft of final valves, holding an asterisk from a provorachivaniye for a shestigrannik. Remove an asterisk.
7. Turn a camshaft of final valves in the provision of the main control. Cams of a camshaft of final valves of the first cylinder should be turned at an angle up. Insert an adjusting finger (3) through an opening in a cover of the forward bearing into an opening of a flange of a camshaft.
8. Remove a chain from an asterisk of a camshaft of inlet valves.
9. Turn a camshaft of inlet valves in the provision of the main control. Cams of a camshaft of inlet valves of the first cylinder should be turned at an angle up. Insert an adjusting finger (3) through an opening in a cover of the forward bearing into an opening of a flange of a camshaft.
The engine with camshaft adjustment: An emphasis located on a circles of an asterisk of a camshaft of inlet valves (2), should be in situation "late" (an emphasis in flange grooves in the direction of rotation of a camshaft) (an arrow above).
10. Establish a chain on an asterisk of a camshaft of inlet valves and on the directing.
11. Insert an asterisk of a camshaft of final valves into a chain and fix on a shaft a new bolt with a fillet the moment 20Нм. Then tighten a bolt a usual key on a corner 90 °.
13. Establish into place a natyazhitel of a chain, address to the Section Removal and installation of a natyazhitel of a chain.
14. Turn the engine in the direction of rotation twice and once again check the main control of camshafts. If necessary repeat adjustment.
15. Establish into place a forward cover, address to appropriate section.
16. Establish a cover of a head of cylinders, address to appropriate section.
