4. Use feeler gage 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 gage (3) between valve bridge
and rocker arm.
3. Readjust adjusting screw (2) so that the
feeler gage (3) 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
Allen key.
5. Check if the feeler gage (3) just passes
through between valve bridge and rocker
arm.
Result: If not, adjust valve clearance.
Final steps
1. Remove barring gear.
2. Install cylinder head cover (→ Page 85).
3. Install air filter (→ Page 101).
