ADJUSTING VALVE CLEARANCES
1. Only turn the crankshaft belt pulley clockwise while adjusting
the valve clearances and start by aligning the mark on the belt
pulley with the "0" mark on the front cover.
2. If belt pulley is now turned to and fro slightly, valves of
cylinder No. 1 or 4 will be rocking, i.e., the two rockers and
push rods move in opposite directions.
3. When valves in cylinder No. 4 are rocking, No. 1 cylinder
valve clearances should be adjusted.
4. Then rotate belt pulley a further half turn. In this position
valves of cylinder No. 3 will rock and valve clearances of
cylinder No. 2 can be adjusted and so on according to firing
order. (See Technical Data for settings. )
Cylinder No. 4 rocking - adjust cylinder No. 1
Cylinder No. 3 rocking - adjust cylinder No. 2
Cylinder No. 1 rocking - adjust cylinder No. 4
Cylinder No. 2 rocking - adjust cylinder No. 3
