NEW TIGHTENING METHOD BY USING PLASTIC REGION TIGHTENING BOLT
Plastic region tightening bolts are used in some parts of the engine. Install these bolts according to the method
described in the body of the manual because the tightening method of these bolts are different from the
conventional method. The service limit is determined for these bolts. Be sure to strictly follow the service limit
described in the body of the manual.
Parts to be used
1. Cylinder head bolt
2. Bearing cap bolt
3. Connecting rod cap bolt
Tightening method
After tightening to the specified tightening torque, further tighten 90° and 90°, or 180° (90° + 90°).
Follow the tightening method described in the body of the manual because the tightening method differs
from part to part.
