Periodic Maintenance Procedures
Be sure to remeasure the clearance after selecting
a shim according to the table. If the clearance is out
of the specified range, use the additional shim.
If there is no valve clearance, use a shim that is a few
sizes smaller, and remeasure the valve clearance.
When installing the shim, face the marked side toward the
valve lifter. At this time, apply engine oil to the shim or
the valve lifter to keep the shim in place during camshaft
Do not put shim stock under the shim. This may
cause the shim to pop out at high rpm, causing ex-
tensive engine damage.
Do not grind the shim. This may cause it to fracture,
causing extensive engine damage.
Apply engine oil to the valve lifter surface and install the
Install the camshaft (see Camshaft Installation in the En-
gine Top End chapter).
Recheck the valve clearance and readjust if necessary.
Install the removed parts (see appropriate chapters).
Exhaust Butterfly Valve Cable Inspection
Remove the left side cover (see Side Cover Removal in
the Frame chapter).
Confirm whether pulley [A] is an angle shown in the figure.
41.7° ±7° [B]
This position is original position of the pulley.
Correct the position electrically after confirming the use
is discontinued and there no damage when differing
from the angle of shown in the figure.
Do not correct the pulley position with the tool,
forcibly. The actuator damage will occur.
If the pulley angle is wrong, adjust the angle as follows.
Turn the ignition switch ON.
Confirm the pulley turns clockwise and then counterclock-
wise, and clockwise again.
The pulley returns to the original position.
Turn the ignition switch OFF.
If the operation of the pulley is different, adjust the exhaust
butterfly valve cables (see Exhaust Butterfly Valve Cable
If the pulley does not return to the original position, adjust
the pulley (see Exhaust Butterfly Valve Actuator Installa-
tion in the Fuel System (DFI) chapter).
