Checking Valve Clearance
IMPORTANT
■
• Valve clearance must be checked and adjusted when engine
is cold.
1. Remove the head cover.
2. Align the 1TC mark of flywheel and the convex of flywheel
housing timing windows so that the first piston (gear case side)
comes to the compression top dead center.
3. Before adjusting the valve clearance of intake valve, adjust the
bridge evenly to the valves stem.
4. Loosen the lock nut (2) and adjust with screw (1).
5. Slightly push the rocker arm (intake side) by your fingers and
screw in the adjusting screw slowly until you feel the screw touch
the top of valve stem, then tighten the lock nut.
6. Loosen the lock nut (4) of adjusting screw (3) (push rod side) and
insert the thickness gauge between the rocker arm and the
bridge head. Set the adjusting screw to the specified value, then
tighten the lock nut.
7. Adjust the clearance between the rocker arm (exhaust side) and
the exhaust valve to the specified value.
NOTE
■
• After adjusting, tighten the lock nut (4) securely.
