on the crankshaft sprocket by three teeth to lower
the piston in No. 1 cylinder slightly from the top
dead center on compression stroke.
Caution
Turning the camshaft sprocket with the piston
in No. 1 cylinder located at TDC on compression
stroke may cause the valves to interfere with the
piston.
sprockets for intake and exhaust valves are not
within the range A in the illustration at left.
If the timing mark is within range A, turn the
camshaft sprocket to move the timing mark to the
area closest to the range A.
Caution
In range A, the cam lobe on the camshaft lifts
the valve through the rocker arm and the
camshaft sprocket is apt to rotate by reaction
force of the valve spring. Therefore, be careful
not to have the finger pinched between the
sprockets.
exhaust valve to locate the timing mark as shown in \
the illustration at left. Then turn the other crankshaft
to locate the timing mark-as shown in the illustration
at left.
Caution
If the intake and exhaust valves of the same
cylinder lift simultaneously, interference with
each other may result. Therefore, turn the intake
valve camshaft sprocket and the exhaust valve
camshaft alternately.

If the camshaft sprocket has been turned excessive-
ly, turn it counterclockwise to align the timing
marks.
NOTE
Shift the timing mark of the crankshaft sprocket one
teeth in counterclockwise direction to facilitate belt
installation.
