Caster Fork Assembly and Bearing Service
Removal
1. Park the machine on a level surface and disengage the PTO. Stop the engine, wait for all moving parts to stop
and remove the key. Engage the parking brake.
2. Raise and support the unit so that the front wheels are off the ground.
3. Remove the caster cap.
4. Support the underside of the caster wheel and remove the fastener screw securing the caster bearing
assembly (A) (Figure 2).
5. Remove the caster fork (B) from the front axle. Inspect the caster fork shaft for wear or damage (Figure 2).
6. Remove the upper and lower bearings from the axle and inspect the inside of the axle bearing area for damage
and excessive wear.
Installation
1. Clean the surface inside the axle bearing area.
2. Install a new lower bearing from the bottom side into the axle, making sure it is fully seated. Press evenly on
the inner and outer race to seat the bearing.
3. Install spring washer on the top side of the axle, followed by a new upper bearing, ensuring that the bearing
is properly seated (the upper bearing should be oating in the housing and does not need to be pressed in
place).
NOTE: The bearings are sealed and do not require grease/lubrication.
4. Install the at washer on top of the bearing.
5. Install the fastener screw and tighten to the caster shaft. The spring washers will provide the appropriate
preload to the bearings.
6. Lower the unit and verify proper function.
