2. Turn the crankshaft clockwise until the mark on the camshaft sprocket matches the mark on the bearing housing, which will correspond to the end of the compression stroke in the fourth cylinder. In this position, the clearance at the exhaust valve of the 4th cylinder is adjusted (8th cam) and inlet valve of the 3rd cylinder (6th cam).
3.Loosen the lever adjusting bolt locknut.
4. Insert a flat feeler gauge A.95111 with a thickness of 0.15 mm between the lever and the camshaft cam and a wrench, tighten or unscrew the bolt 2, followed by tightening the lock nut 3, until the feeler gauge 1 enters with a slight pinch when the lock nut is tightened.
5. After adjusting the gap at the exhaust valve of the 4th cylinder and the inlet valve of the 3rd cylinder, turn the crankshaft 180°sequentially and adjust the gaps, observing the sequence indicated in the table.
Valve clearance adjustment sequence
Angle of rotation of the crankshaft | The number of the cylinder in which the compression stroke occurs (end) | Number of adjustable valves (cams) |
0° | 4 | 8 and 6 |
180° | 2 | 4 and 7 |
360° | 1 | 1 and 3 |
540° | 3 | 5 and 2 |
