HD-95637-46A) with BEARING RACE REMOVER/
INSTALLER (Part No. HD-34902B) and END CAP (Part
No. HD-34902-7). Apply heat to race to aid removal.

8. See Figure 3-147. Press new inner race on pinion shaft
as shown. When the tool bottoms against the flywheel,
correct inner race location is automatically established.
The new inner race must be ground by a competent
machinist to OD dimension range for the finished lapped
ID of the outer race. See

ing outer race undersize and gives a more easily
achieved tolerance range.
If you are unable to perform this operation, Harley-David-
son Motor Company provides a flywheel refurbishing
program as outlined in Tech Tip #38.
Always use the smallest outer race ID measurement and
the largest OD inner race measurement when selecting
bearings.
9. The following example illustrates how to determine the
required inner race OD.
a. See Table 3-31. For example purposes, suppose the
smallest outer race ID measurement is 1.5651 in.
(39.754 mm). This requires an inner race OD range
of 1.2496-1.2504 in. (31.740-31.760 mm).
b. Grind inner race. Measure OD at four places. Check
that specifications in Step 8 are met.
c. For example purposes, suppose the largest inner
race OD measurement after grinding is 1.2499 in.
(31.747 mm) OD.
d. With a 1.5651 in. (39.754 mm) ID outer race and a
1.2499 in. (31.747 mm) OD inner race, a blue bear-
ing is required.
This will prevent grind-
