HOW TO SET THE CAMSHAFT TIMING
When replacing the camshaft, set the timing as
follows.
1. Secure propeller.
NOTE:
If propeller is not secured, crankshaft may
move backward and correct timing cannot
be set.
2. Turn the crankshaft so that T mark on the
drive hub may match crankcase center line.
(This is engine T.D.C. position)
3. Push the camshaft into camshaft housing
until it stops. Locate ' •' mark on the side of
camshaft gear in line with the push rod.
4. Rotate crankshaft right and left a little
and
make sure that the ' •' mark on the gear is in
line with the push rod when the ' T ' mark
on
the drive hub matches the crankcase center
line.
5. Secure cam cover with screws.
The relation of position between ' • ' mark of
the gear and teeth may differ from the sketch,
by each model.
