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. 167) and remove
the sprag and spring. Then remove the spring clip
and reaction plug (Fig. 168). 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. 169).
Also be sure the spring is correctly positioned as
shown (Fig. 169). The sprag may not retract if the
spring is improperly installed.
