9. Remove the bearing cone from the bearing
carrier. Gently tap out the bearing cups
and remove the bearing spacers.

Inspection
1. Clean bearings and other components
using parts cleaner.
2. Carefully inspect bearings and seals for
signs of excessive wear. The bearings,
shims, and spacers are a matched set and
must be replaced as a unit. Order using
Hale p/n: 250-8140-50-0.
3. Obtain new components from Hale Prod-
ucts as appropriate.
Reassembly and Installation
See Figure 8: "Tail Shaft Assembly."
1. Using retaining ring pliers, install retaining
ring into bearing carrier.
2. Insert, on top of the retaining ring, the outer
bearing spacer, then press in the bearing
cup.
Be careful not to mix bearing components
with those from other bearing sets. Should
the outer spacer be confused with that
from the bearing carrier, the one used for
the tail shaft assembly is noticeably thinner
than the bearing carrier spacer.
3. To the tail shaft, press on the roller bearing
inner race (see Figure 8 above).
4. Slide the matching inner bearing cone and
spacer onto the tail shaft. Both are a tight
fit.
