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: 250-8140-53-0.
3. Obtain new components from Hale Products as appropriate.
Reassembly and Installation
See Figure 9-7, “Tail Shaft Assembly,” on page 162
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.
Note: 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 9-7: above).
4. Slide the matching inner bearing cone and spacer onto the tail shaft. Both are a
tight fit.
5. Insert tail shaft into gearbox housing, aligning inner race of roller bearing with
outer race on the mating input shaft. Also see Figure 9-8: “Shaft End Gap”.
