Size 4608 with fan on back side — Seal cage without
seal, one .015" (0,38 mm) shim-gasket and cross tighten
fasteners to torques specified in Table 14, (Ref. #39, 40
and 63). Seal will be added later.
Size 4608 with external backstop — Seal cage without
seal, one .015" (0,38 mm) shim-gasket and cross tighten
fasteners to torque specified in Table 14, (Ref. #39, 40
and 66). Seal will be added later.

SHAFT ASSEMBLIES —
Where bearings and gears were
not removed from the shafts, skip to Step 5. If bearings
and gears were removed from the shafts, reassemble
parts on the shaft per Figures 18 thru 21 as follows:
a) To assemble gear (Ref. #1A4 or 4A4), heat gear in an oven
to 275°F(135°C) and press onto the shaft & firmly against
the shoulder. For Size 4608, be sure to place spacers in the
proper location on shaft assemblies 2A and 4A, before
pressing on the bearings.
b) To assemble bearings, heat bearing cone in an oven to a
maximum of 275°F(135°C), then slide or press them tight
against the shaft shoulder or spacer.
CAUTION:
Allow assembly to cool. Apply a coat of oil to
the cooled bearings and gear teeth to lubricate & avoid
scoring of the working surfaces.
5.
DRIVE ASSEMBLY —
Turn drive housing base on work
bench to allow the shaft assemblies to be lowered into the
housing. Block up the housing so that when low speed shaft
assembly, 4A, is in place, the threaded end of the shaft will
clear the bench surface. Before assembly, inspect housing
and all shaft assemblies to see that all foreign matter has
been removed.
Use eye bolts to assist in lowering high speed shaft and low
speed pinion assemblies (Ref. #1A, 2A and 3A) into the
housing base. Lift the low speed shaft assembly (Ref. #4A) by
slinging thru holes in the gear web. Assemble as follows:
a)
SINGLE REDUCTION —
Lower high speed shaft
assembly, Ref. #3A, Figure 19, into housing and tip away
from other housing bores. While lowering the low speed
shaft assembly, Ref. #4A, Figure 21, into housing tip high
speed shaft into the gear mesh of the low speed gear as
the shaft nears final position.
b)
DOUBLE REDUCTION —
Lower high speed shaft
assembly, Ref. #1A, Figure 18, into housing and tip away
from other bores. Simultaneously lower the intermediate
shaft assembly, Ref. #2A, Figure 20, and the low speed
shaft assembly, Ref. #4A, Figure 21, into the housing. As
shafts approach their final position, tip the high speed
shaft pinion into the high speed gear mesh, Ref. #1A4.
