INSTALLING THE CAMSHAFTS
1. Install:
• Exhaust camshaft
• Intake camshaft
a. Turn the crankshaft clockwise.
b. When piston #1 is at TDC on the compres-
sion stroke, align the “I” mark “a” on the
generator rotor with the stationary pointer
“b” on the generator cover.
c. Install the timing chain onto both camshaft
sprockets, and then install the camshafts
onto the cylinder head.
TIP
• Lubricate the camshaft journal with the molyb-
denum disulfide oil.
• When installing the timing chain, start with the
exhaust camshaft and be sure to keep the tim-
ing chain as tight as possible on the exhaust
side.
• The camshafts should be installed onto the cyl-
inder head so that the alignment marks “c” on
the intake camshaft sprocket and the align-
ment marks “d” on the exhaust camshaft
sprocket align with the cylinder head mating
surface, as shown in the illustration.
NOTICE
