CLEANING AND INSPECTION
GOVERNOR AND PARK GEAR
Thoroughly clean all the governor parts in a suit-
able cleaning solution but do not use any type of
caustic cleaning agents.
The governor weight components (Fig. 218) and the
governor valve (Fig. 219), must slide freely in their
bores when clean and dry. Minor surface scratches
and burrs can be smoothed with crocus cloth.
The aluminum governor valve and outer weight
have a hard coating on them. Check condition of this
coating carefully. Do not reuse either part if the coat-
ing is damaged.
Inspect the governor weight spring for distortion.
Replace the spring, if distorted, collapsed, or broken.
Clean the filter in solvent and dry it with compressed
air. Replace the filter, if damaged. Inspect the park
gear for chipped or worn gear teeth or damaged ring
grooves. Replace the gear, if damaged.
Check the teeth on the park gear for wear or dam-
age. Replace the gear if necessary. Inspect the metal
seal rings on the park gear hub. Replace the rings
only if severely worn, or broken.
EXTENSION HOUSING AND PARK LOCK
Clean the housing and park lock components in
solvent and dry them with compressed air.

Examine the park lock components in the housing.
If replacement is necessary, remove the shaft with
parallel jaw snap ring pliers (Fig. 220) and remove
the sprag and spring. Then remove the spring clip
and reaction plug (Fig. 221). Compress the reac-
tion plug spring clip only enough to remove
and install it. Do not distort the clip during
removal or installation.
Be sure a replacement sprag is installed so the
sprag locking lug will face the park gear (Fig. 222).
Also be sure the spring is correctly positioned as
shown (Fig. 222). The sprag may not retract if the
spring is improperly installed.

Serviceable valve body components are:
• park lock rod and E-clip
• switch valve and spring
• pressure adjusting screw bracket
• throttle valve lever
