Section III
Drive Reassembly
Refer To Parts Drawing Figures 14 & 15.
1.
GENERAL
a) Clean all parts to be reassembled and coat all taper roller
bearing cups and pinion teeth with oil. DO NOT
lubricate gear teeth prior to assembly on shaft.
b) Heat all tapered roller bearing cones in an oven to
275°F(135°C).
CAUTION:
Do not apply flame directly to bearings or rest
bearings directly on a heated surface.
c) Slide or press all bearing cones tight against the shoulder
or spacer.
CAUTION:
Do not apply force to the bearing outer race.
Apply force against the inner race only.
2.
ASSEMBLY OF ROLLER BEARING CUPS —
Where
bearings will be reused and where bearing cups were not
removed from the housing, skip to Step 3. It is
recommended that bearings be replaced when ever drive is
disassembled after being in service.
Install bearing cups only in housing base at this time. Coat
bearing cups and housing bores with an SAE 20(or heavier)
oil and drive or press cup squarely into the housing bores
until positioned as shown in Figure 16 and 17. Use a flat
plate and a brass bar to avoid damaging the bearing cups.
NOTE, that the exact positioning of the bearings in the
bores will be achieved during the bearing adjustment
procedure in Step 6.
CAUTION:
Take care not to allow cups to cock during their
installation as this could result in permanent damage to
housing.
If cups become cocked in the bores, tap the high side lightly to
re-position.
3.
ASSEMBLE SEAL CAGES TO HOUSING OUTPUT SIDE
(BASE) AS FOLLOWS:
a) Turn housing on work bench to its side being careful that
the bearing cups do not fall out of the bores. Assemble
low speed seal cage without seal and one .015" (0,38
mm) shim-gasket, Ref. #11 or 12 and 24 for Sizes 4407
- 4507 & Ref. #22 or 27 and 23 for Size 4608. Cross
tighten fasteners, Ref. #34 for Sizes 4407- 4507 & Ref.
#24 for Size 4608, to torque specified in Table 14.
Check to be sure that cages and covers are registered on
the bearing cups to avoid hanging up of the cups.
b) Assemble intermediate end cover and one .015" (0,38 mm)
shim-gasket, Ref. #15 and 25 for Sizes 4407 - 4507 & Ref.
#29 and 30 for Size 4608. Cross tighten fasteners, Ref.
#35 for Sizes 4407- 4507 and Ref. #31 for Size 4608, to
torque specified in Table 14.
c) Assemble high speed pinion shaft cover or seal cage
without seal as follows:
Size 4407 - 4507 without backstop — Shaft cover, one
.015" (0,38 mm) shim-gasket and cross tighten fasteners
to torque specified in Table 14. (Ref. #17, 27 and 37 for
Type J05 & Ref. #18, 28 and 37 for Type J14 & J25).
Size 4407- 4507 with backstop — Backstop cage, shaft
cover, shim-gaskets and finger tighten the fasteners, Ref.
#19, 20, 29, 30 and 38. The backstop will be installed
following assembly of shaft assemblies into drive housing.
Size 4608 without backstop — Shaft cover, one .015"
(0,38 mm) shim-gasket and cross tighten fasteners to
torque specified in Table 14, (Ref. #39, 40 and 65).
