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 torque, further
tighten 45

° 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.
