13. Rotate the crankshaft counter-clockwise so that

the keyway is at approximately 11 o’clock. The

timing dot should line up with a circular moulding

behind the sprocket (on the oil pump, as shown).

CAUTION: Rotate the crankshaft

counter-clockwise only. Do not rotate past the

position shown or sever piston and valve

damage can occur.

housing.

18. (Optional) Using the special tool, rotate the

crankshaft counter-clockwise and check the

alignments of the timing dots and marked links.

RH cam sprocket timing dot/links should be at

approximately 11 o’clock, LH cam sprocket timing

dot/links should be at approximately 1 o’clock and

the crankshaft sprocket timing dot/links should be

at approximately 6 o’clock (bottom).

CAUTION: The tensioner arms may need

to be moved to take any slack after the check

as the chains may be loosened.
