CHECKING AND CLEANING DRAINS
HDX283A
1. Inspect the “duck-bill” drain beneath the main hous-
ing for debris and for proper sealing.
2. Remove the drain tube and clean out any water, oil,
or debris. Reinstall and secure with the clamp.
Valve/Tappet Clearance

NOTE: The engine must be cold for this procedure.

NOTE: The seat, seat back, seat base, and spark
plug must be removed for this procedure.
1. Remove the spark plug and timing inspection plug;
then remove the tappet covers (for more detailed
information, see Engine/Transmission - Servicing
Top-Side Components).
2. Rotate the crankshaft to the TDC position on the
compression stroke.

NOTE: At this point, the rocker arms and adjuster
screws must not have pressure on them.
CHECKING
Using a feeler gauge, check each valve/tappet clearance.
If clearance is not within specifications, loosen the jam
nut and rotate the tappet adjuster screw until the clear-
ance is within specifications. Tighten each jam nut to 7
ft-lb after completing the adjustment.

ADJUSTING
A. Place the Valve Clearance Adjuster onto the jam nut
securing the tappet adjuster screw; then rotate the
valve adjuster dial clockwise until the end is seated
in the tappet adjuster screw.
B. While holding the valve adjuster dial in place, use
the valve adjuster handle and loosen the jam nut;
then rotate the tappet adjuster screw clockwise until
friction is felt.
C. Align the valve adjuster handle with one of the
marks on the valve adjuster dial.
D. While holding the valve adjuster handle in place,
rotate the valve adjuster dial counterclockwise until
proper valve/tappet clearance is attained.

NOTE: Refer to the specifications in CHECKING
for the proper valve/tappet clearance.
 NOTE: Rotating the valve adjuster dial counter-
clockwise will open the valve/tappet clearance by 0.05
mm (0.002 in.) per mark.
E. While holding the adjuster dial at the proper clear-
ance setting, tighten the jam nut securely with the
valve adjuster handle.
3. Install the spark plug; then install the timing inspec-
tion plug.
4. Place the two tappet covers with O-rings into posi-
tion. Tighten the cap screws to 8 ft-lb.
CAUTION
A torn air filter can cause damage to the vehicle engine. Dirt
and dust may get inside the engine if the element is torn.
Carefully examine the element for tears before and after
cleaning it. Replace the element with a new one if it is torn.
CAUTION
The feeler gauge must be positioned at the same angle
as the valve and valve adjuster for an accurate measure-
ment of clearance. Failure to measure the valve clear-
ance accurately could cause valve component damage.
