[Removal]
• Before loosening the cylinder head bolts 8, loosen the adjusting screw C on every rocker A that is compressing its valve spring B.

Loosen and remove the cylinder head bolts 8 in the sequence shown. Each cylinder head bolt should be loosened a little at a time.

[Fitting]
• The M14 cylinder head bolts 8 can be reused only three times.CAT ET 2022A
Before refitting the cylinder head bolts, make a punch mark on the head of each one to indicate times of reuse.

If any bolt already has three punch marks, it must not be reused any more; replace it with a new one.
• Tighten the cylinder head bolts 8 to the specified torque {M14 bolts:78 N·m (8 kgf·m) [57.5 lbf·ft]; M10 bolts: 17 N·m (1.75 kgf·m) [12.5
lbf·ft]} in the sequence shown. Then, turn the bolts further in accordance with the following procedure.

G: Rod (extension)

• Set the socket such that the built-in spring force forces the rod G against the rocker shaft bracket, an injection pipe, or another nearby part.
• On the holder D, select the inscribed line H that is easiest to see.
• Using the selected line as a reference, turn the socket E 180° clockwise. (One gradation on the scale J represents 5°.)
CAUTION
Since the M14 cylinder head bolts 8 utilize the plastic region tightening method, they must not be tightened further after this procedure.

<M10 Bolts>
• After fitting the M14 cylinder head bolts 8, tighten the M10 bolts to the specified torque {34 N·m (3.5 kgf·m) [25.1 lbf·ft]} in the sequence shown.
