Figure 3-130. Removing Pinion Bearing Inner Race
NOTES
• For necessary dimensions for constructing a press on tool
for the pinion bearing inner race, see
Figure 3-129 .
• The new inner race must be ground by a competent
machinist to OD dimension range for the finished lapped
ID of the outer race. Refer to
Table 3-29 .
9. See Figure 3-131 . Press new inner race on pinion shaft
as shown. When the tool bottoms against the flywheel,
correct inner race location is automatically established.
The finished inner race must meet the specifications in
Table 3-32 .

Figure 3-131. Inner Race Location
NOTES
• Have machinist grind inner race to center or middle of
required OD range in
Table 3-29 . This will prevent grinding
outer race undersize and gives a more easily achieved
tolerance range.
• If you are unable to perform this operation, Harley-Dav-
idson 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.
10. The following example illustrates how to determine the
required inner race OD.
a. Refer to Table 3-29 . 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. Refer
to
Table 3-32 .
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 bearing
is required.
Lapping Pinion Shaft Bearing Outer Race
1. Secure right and left crankcase halves with three crank-
case stud bolts (top center and bottom left and right). The
sprocket shaft bearing outer races and large spacer must
be installed in left crankcase.
2. See Figure 3-132 . Obtain CRANKCASE MAIN BEARING
LAPPING TOOL (Part No. HD-96710-40D). Assemble
