ADJUSTING CAMSHAFT-TO-ROCKER ARM
CLEARANCE
See
fi
gure 14.
Inspect the camshaft-to-rocker arm clearance after every
25 hours of operation or if the engine can't go idle or if the
wide open throttle speed is too low. This should be done
in a clean, dust-free environment.
NOTE:
This procedure requires partial disassembly of the
engine. If you are unsure if you are quali
fi
ed to perform this
operation, take the product to a quali
fi
ed service centre.
■
Stop the engine.
■
Remove the screw from the top engine cover. Remove
engine cover and set aside.
■
Using a wrench-T20, remove the screw from the
rocker arm cover. Remove the cover and set aside.
■
Position camshaft by pulling the starter grip and rope
just until the deep hole in the camshaft gear is located
at the 6 o'clock position as shown.
■
Place the feeler gauge under each rocker arm and
measure the gap. The gap should be between 0.1 mm
and 0.15 mm for both rocker arms.
NOTE:
Use a standard automotive feeler gauge. The 0.1
mm feeler gauge should slide between the rocker arm
and valve stem with a slight amount of resistance but
without binding. The 0.15 mm feeler gauge should not
slide between rocker arms and the cam lobes- it should
be held tight.
■
If the valve clearance is not between 0.1 mm and 0.15
mm, the clearance should be adjusted as follows:
●
While holding the wrench on the flats of the
adjusting nut with one hand, firmly loosen the
retaining nut with a second wrench as shown.
Take care not to loosen the stud.
●
Rotate the adjusting nut until it touches the feeler
gauge. Once the gap setting is correct, hold
the wrench on the flats of the adjusting nut and
retighten the retaining nut securely.
■
Adjust the second rocker arm, if necessary.
■
Replace the rocker arm cover and screw; tighten
securely.
■
Replace the top engine cover and screw; tighten
securely.
WARNING
Ensure all engine cover and all engine parts are
completely and properly reassembled before starting
engine. Failure to correctly reassemble engine could
result in serious injury or property damage.
