NEW TIGHTENING METHOD – BY USE OF BOLTS TO BE TIGHTENED IN PLASTIC AREA

A new type of bolts, to be tightened in plastic area, is currently used some parts of the engine. The tightening method for the bolts is different from the conventional one. Be sure to observe the method
described in the text when tightening the bolts.
Service limits are provided for the bolts. Make sure that the service limits described in the text are strictlyobserved.

Areas where the bolts are in use:
(1) Cylinder head bolts
(2) Main bearing cap bolts
(3) Connecting rod cap bolts

Tightening method
After tightening the bolts to the specified torque, tighten them another 90° or 180° (twice 90°). The tightening method varies on different areas. Observe the tightening method described in the text.
