10. See 

 Pull inner race from pinion shaft using

CAP (Part No. HD-95652-43A), and BEARING SEPARA-
TOR (SNAP-ON TOOLS Stock No. CJ950). Apply heat to
race to aid removal.

11. See 

 Press new inner race on pinion shaft as

shown. The new inner race must be ground by a compe-
tent machinist to OD dimension range given in the 

ION SHAFT BEARING SELECTION TABLE

, for the

finished lapped ID of the outer race. The finished inner
race must meet these specifications. For necessary
dimensions for constructing a press-on tool see 

 When the tool bottoms against the flywheel, correct

inner race location is automatically established.

Roundness: within 0.0002 in. 
Taper: within 0.0002 in. (0.005 mm)
Surface finish: 16 RMS

12. The following example illustrates how to determine the

required inner race OD.

EXAMPLE:

a.  If smallest measured ID of outer race is 1.5651 in.

(39.754 mm) Table 13 indicates an inner race OD
range of 1.2496-1.2504 in. (31.740 - 31.760 mm) is
required.

NOTE

Have machinist grind outer race to center or middle of
required OD range. This will prevent grinding outer race
undersize and gives a more easily achieved tolerance range.

b.  Grind inner race. Measure OD at four places and

check that specifications in Step 11 are met.

c. 

For example purposes, the largest measured OD of
inner race after grinding is 1.2499 in. (31.747 mm)
OD.

d. See 

 With a 1.5651 in. ID outer race and

a 1.2499 in. (31.747 mm) OD inner race, a blue
bearing is required.

NOTE

Always use the smallest outer race ID measurement and the
largest OD inner race measurement when selecting bearings.
