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.
