Toro 4100-D service manual Differential Gear Removal

Differential Gear

The following procedures assume the rear axle assem- bly has been removed from the machine (see Rear Axle Assembly Removal in this section).

Differential Gear Removal

1.Remove bevel gear case/axle case assemblies (see Bevel Gear Case/Axle Case Assembly in this section of this manual).

IMPORTANT: Do not interchange right and left dif- ferential shafts assemblies.

2.Mark and pull the differential shaft assemblies from the axle support.

3.Remove input shaft/pinion gear assembly, shims and O-ring from the axle support (Fig. 34).

4.Remove the axle support case screws. Separate the axle support halves and remove the O-ring.

5.Remove the differential gear assembly, bearings and adjusting shims from the axle case.

6.Drive the spring pin from the differential case with a punch and hammer. Discard the spring pin (Fig. 35).

NOTE: Mark and arrange all components so they can be reassembled in their original position.

7.Remove the differential pinion shaft, pinion gears and pinion washers. Remove the differential side gears and side gear shims. Remove the ring gear only if it will be replaced (Fig. 36).

NOTE: Replacement ring gears are only available in matched ring and pinion sets.
