Differential Axle Bearing (Countershaft Housing)
Removal
1. Park mower on a level surface. Make sure engine
is OFF. Remove high tension lead from the spark plug.
2. Lower handle to allow a clearance for the removal
of the bearing and flangettes from the differential axle
(see Handle in the Adjustments section of Chapter 6 –
Wheels and Accessories).
Note: The locking collar securing the left differential
axle to the countershaft housing is a eccentric flange
type.
3. Loosen the set screw on the locking collar. Unlock
collar by striking it with a punch in the clockwise direction
(Fig. 38).
4. Remove bearing housing on the side plate for the
left differential axle (see Differential Axle Pulley and
Bearing Removal).
5. Slide locking collar off the differential axle.
6. Remove jam nuts (13), lock washers (12), and cable
clip (15) from the studs of screw plate (5) (Fig. 33).
IMPORTANT: Before removing the flangettes and
bearing from the differential housing, support the
axle in its original position to prevent possible dam-
age to the remaining differential axle bearing.
7. Slide flangettes (6 and 8) and bearing (9) of the dif-
ferential axle (Fig. 33).
