8. Remove the cotter pin (B) from the castle
nut (C), and remove the castle nut (30mm
socket).
9. Remove the spacer (D) and the inner
bearing cone (E).
The steering chain needs to be freed from the
steering shaft sprocket. This can be completed
in one of two methods depending on which
affords the easier access. You can either remove
the masterlink from the chain (step 10), or
remove the steering sprocket from the shaft
(step 11). Regardless which method you use,
you will probably ๎nd that reassembly is best
using the masterlink.
10. If accessible, remove one of the two
masterlinks (K) holding the steering chain
to the steering disk, and free the chain
from the smaller steering sprocket.
11. Alternatively, from under the machine just
behind the front bumper, loosen the two
setscrews from the smaller steering sprocket
(F).
a. Slightly raise the machine just enough to
take the weight off the front wheel and allow
the lower cone bearing to misalign with its
outer race (move slightly side to side).
b. With slack on the steering chain, you
should be able to remove the small steering
sprocket from the steering shaft. Take care
to not lose the woodruff key in the steering
shaft.
12. While supporting the drive wheel, raise the machine until the steering spindle is free from the hub, and
remove the wheel motor from the machine.
13. If you remove the phase wires from the motor, make sure to label them for correct replacement.
14. Using a seal puller, remove the lower seal (G) and discard the seal.
15. Remove the lower cone bearing (H).
16. Clean the old grease out of the steering hub, and inspect the two bearing cups (J) that are pressed into
the hub. If the cups need to be replaced, remove them with a bearing puller.
