1 Check valve clearance (arrows) with feeler gage between rocker arm and valve bridge.
Only maintenance: The valve clearance must not be set if it is within the inspection tolerance.
2 Adjust valve clearance (arrows).
For this step slacken locknut (2) and adjust valve clearance with adjusting bolt (1). Afterwards counterhold adjusting bolt (1) and tighten locknut (2) fully.
3 Check again valve clearance, if necessary repeat adjustment.
The valve clearance is correctly set, if it is possible to plunge the feeler gage
with a slight resistance.
