Inspection: Camshaft end play
• If the measurement exceeds the limit, replace the defective
part(s).

Releasing valve spring force

• Before loosening the rocker and bracket assembly mounting
bolts, check whether the valve springs are compressed by the
rockers. If so, loosen the adjusting screws on the rockers to re-
lieve the spring force. This will eliminate the possibility of com-
pressed springs damaging parts when they are released.

Removal: Camshaft

• Remove the plug at the rear end of the cylinder head.
• Insert a sub-gear locking bolt (M8 × 1.25 mm, length 20 mm)
into the dedicated hole in the No. 3 idler gear to lock the sub-
gears. Remove the camshaft.

Installation: Rocker case

• Tighten the rocker case bolts in the order shown in the illustra-
tion.
Installation: Camshaft
• Make sure that the timing marks on the timing gears are aligned
with each other.
• Install the camshaft so that the stamped line on the camshaft
gear is level with the top surface of the rocker case.
• Install the plug at the rear end of the cylinder head. (See later
pages.)
