Reassembly Notes
Any time the drive wheel assembly is removed, it is
a good practice to inspect and repack the steering
spindle bearings. This will also require replacing the
seal (24).
1. Using a screwdriver, pry the seal out of the
steering plate. Discard the seal.
2. Remove the thrust bearing cone (25) and clean
the old grease from the cone and also from the
upper bearing (27), which is not removable.
3. Inspect the bearings and cup (26) for wear and
replace if necessary.
4. Repack the bearings with axle grease.
5. Replace the old seal with a new seal.
6. Wipe off accumulated grease and debris from the
steering spindle (28).
7. When tightening the steering spindle nut (8),
torque the nut to 20 ft-lbs.
8. During reassembly, inspect/adjust the steering
chain tension as described on page 91.
