GEARCASE BEARING AND SEAL
REPLACEMENT
NOTE
If the gearcase is assembled, perform the “Gearcase
Disassembly and Inspection” procedure.
1. Remove the nut and lock washer from the pinion
shaft (if necessary, hold the coupler in a vise to
remove the nut).
2. Remove the coupler from the pinion shaft by using
two pry bars in the areas shown. If the coupler is
difficult to remove, use a universal bolt-grip puller to
prevent any damage.
3. Remove the seal above the pinion shaft using a seal
puller or other suitable method (see Figure 8-27).
4. Remove the retaining ring and lift the pinion shaft
and bearing from the main gearcase (see Figure 8-
27).
NOTE
If the pinion shaft will not lift out of the gearcase,
reinstall the coupler and finger tighten the retaining nut.
Use two pry bars to lift the pinion shaft assembly out.
5. Support the pinion shaft and press the bearing off the
shaft (see Figure 8-27).
6. Thoroughly clean the pinion shaft.
WARNING
Wear appropriate safety equipment while installing
bearings to reduce the risk of injury.
7. Support the pinion shaft and carefully press the new
bearing on the shaft and install a new O-ring (see
Figure 8-27).
NOTE
Carefully inspect the pinion shaft gear before replacing
the bearing. If the gear teeth are damaged, the shaft
must be replaced as an assembly.
