1. Inspect all reused cylinder head bolts according to

the following procedure.
(1) Measure the outside diameter shown in the

illustration (arrow "A").

(2) Measure the smaller outside diameter shown

in the illustration (arrow "B").

(3) When the difference between the outside

diameters (arrow "A" and "B") exceeds the
standard value, replace the cylinder head bolt.

Standard value: 0

− 0.15 mm

2. Install the cylinder head bolts and washers onto

the cylinder head.
