Caution

  •  pull the cam chain upward, or the chain will be caught between crankcase and cam drive sprocket.
  •  To adjust the camshaft timing correctly, be sure to align the line “a” with slit “b” and hold this position when installing the camshafts.

Note

  •  damage to head or camshaft journal holder thrust surfaces may result if the camshaft journal holders are not drawn down evenly.
  •  Each camshaft journal holder is identified with a cast-on letter “f”.
  •  The ascending order of numbers are indicated on the camshaft journal holders.

Tightening torque camshaft journal holder bolt: 10 n·m (1.0 Kgf-m, 7.0 Lbf-ft)

Caution

the camshaft journal holder bolts are made of a special material and much superior in strength, compared with other types of high strength bolts.

Take special care not to use other types of bolts.

Cam chain tension adjuster

Caution

do not turn the adjuster body until the outer circlip “a” exceeds the groove “b”.

If the inner circlip “c” is caught in the groove “b”, plunger may not go out automatically from the adjuster body even if pushing force is applied on the head.

In such case, it needs to be disassembled.
