Inspection procedure
Installation procedure
Inspection: Interference between camshaft gear and cam-
shaft
• If the measurement deviates from the standard value, replace
the defective part(s).

Inspection: Camshaft

(1) Cam lift

• If the measurement (difference between lobe diameter and base
circle diameter) is less than the limit, replace the camshaft.

(2) Bend

• Measure the camshaft at the center journal for bend while sup-
porting the shaft at the end journals.
• A half of the dial gauge reading obtained as the camshaft is ro-
tated by a full turn represents the bend of the camshaft.
• If the measurement exceeds the limit, replace the camshaft.

(3) Oil clearance at journal

• If the measurement exceeds the limit, replace the defective
part(s).
CAUTION
• The rocker case and the brackets of the rocker and bracket
assembly have been machined together, which means that
they all must be replaced together.
Installation: Camshaft gear
• Heat the camshaft gear to approximately 150°C using a gas
burner.
• While facing the camshaft gear as shown in the illustration,
press it onto the camshaft until it seats snugly on the camshaft.
WARNING
• The camshaft is extremely hot. Be careful not to touch it.
