Check of phase installation of camshafts

Engine 111

Check

 PERFORMANCE ORDER

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

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

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

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

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

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

7. Remove an adjusting finger.


Phasing correction

 PERFORMANCE ORDER

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