4. Use feeler gauge to determine the distance between valve bridge and rocker arm.
5. If the deviation from the reference value exceeds 0.1 mm, adjust valve clearance.
Adjusting valve clearance
1. Loosen locknut (1) and unscrew adjusting
screw (2) by a few threads.
2. Insert feeler gauge between valve bridge
and rocker arm.
3. Readjust adjusting screw (2) so that the
feeler gauge just passes through the gap.
4. Tighten locknut (1) with torque wrench to
the prescribed tightening torque of 50 Nm
while holding the adjusting screw (2) with
screwdriver.
5. Insert feeler gauge between valve bridge
and rocker arm to verify that the gauge just
passes through the gap.
Result: If not, adjust valve clearance.
