Illustration 4 g01353909 Tightening sequence for the valve mechanism cover - Tighten bolts (1) and (3) in the numerical sequence that is shown in Illustration 4. Tighten the bolts to a torque of
6 N·m (53 lb in) . - If the valve mechanism cover is equipped with a heat shield, install the heat shield. Tighten the bolts to a torque of
9 N·m (79 lb in) .
End By:
- Connect the crankcase breather or install the crankcase breather. Refer to Disassembly and Assembly, "Crankcase Breather - Install".
