SECTION 4
REPAIRS TO GEARCASE AND PLANETARY
NOTE: Grease is not shown in these pictures.
A. Examine the bearings in the attachment hub area
and top of the gearcase.
These bearings are cast into the gearcase-motor
housing.
If they are worn badly, the entire housing must be
replaced.
However, shafts turn slowly in these bearings and
the bearings have a long life.
B. Examine the attachment hub bevel gear.
If it shows wear in the teeth, it should be replaced.
If the gear is replaced, coat the shaft of the bevel
gear with a light grease.
Push it into the attachment hub bearing from the
inside of the gearcase (Fig. 51). It does not have a
washer, so push it in as far as it will go.

the attachment hub bearing from inside the gearcase.
C. With a phillips head screwdriver, remove the
three #10-24x7/16” phillips filister head screws and
lock washer assemblies and lift up on the worm
gear bracket bearing and pin assembly to remove
(Fig. 52).

D. Remove the center bevel gear and vertical center
shaft.
Push the vertical center shaft upward, exposing the
pin (Fig. 53), and remove the pin.
Fig. 53 Remove pin after pushing vertical center shaft up.
Pull out the vertical center shaft with your fingers
and remove the shaft from the the bottom of the gear
case bottom cover (Fig. 54).
Check the shaft for bearing wear.
Dark gray or indented surfaces indicate shaft
should be replaced.
Lift gears from case for inspection (Fig. 55).
