DRIVE SYSTEM
Installing the Differential
10
Clean all grease and oil from the axle shafts, pillow block bearings and locking collars.
11
Install the sprocket, brake drum, pillow blocks, and wheels on the new differential.
12
Install the differential assembly on the frame. If there were shims between any of the pillow blocks and
frame members, be sure to install them on the same frame member that they were on originally.
13
Center the differential within the frame and tighten the locking collars and set screws on each pillow
block.
14
Turn the wheels to check for binding. If the wheels are difficult to turn, the differential is not properly
aligned or one of the axles are bent. Install shims between the pillow blocks and the frame members as
required to make the wheels turn freely.
15
Install the brake band, chain, batteries, and cables.
16
Test the machine for proper operation.

CASTER REPLACEMENT
The caster wheel is located on the back of the 260, and on the front of the 32, 38, 320, 380. The bearings in
the swivel portion of the caster seldom fail. The bearings in the caster wheel are usually damaged by debris
wrapping around the axle and damaging the seals, or from lack of lubrication.
To replace the caster wheel:
1
Drain the solution and recovery tanks.
2
Use a jack to lift the caster-end of the machine off of the floor slightly.
3
Remove the axle nut and bolt and remove the caster wheel.
4
Install the new caster wheel and pump grease into the bearings with a grease gun (if applicable).
5
Test run the machine to make sure that the caster turns freely.
