Note:
Check and adjust the valve clearance and unit
injectors at the same time and with the engine cold.
Checking and adjusting the valve clearance:
1.
Turn the flywheel with tool 8405 so that the piston in cylinder
No. 1 is at TDC after compression.
2.
Check the valve clearance using a feeler gauge and, if necessary,
use the adjusting screw on the rocker arm to set the correct
clearance.
The clearance for intake valves should be 0.45 mm
and the
clearance for exhaust valves should be 0.70 mm
when the engine is cold.
The intake valves are actuated by the short rocker arms and the
exhaust valves by the long rocker arms. Make sure the valve
bridge is resting correctly against the valves.
See the table next page.
