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 17 thru 20 as
follows:
a . To assemble gear (Ref . #1A4 or 4A4), heat gear in
an oven to 325°F (163°C) . Install key . Press gear
onto the shaft tightly against the shoulder . For size
5608, be sure to place spacer, Ref . #4A6, Figure 20,
in the proper location on shaft assembly, Ref . #4A,
before pressing on the bearing .
b . To assemble bearings, heat bearing cone in an oven
to a maximum of 275°F (135°C), then slide or press
bearing cone 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.

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, Ref . #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 .
a .
SINGLE REDUCTION
— Lower high-speed shaft
assembly, Ref . #3A, Figure 18, into housing and tip
away from other housing bores . While lowering the
low-speed shaft assembly, Ref . #4A, Figure 20, into
housing tip high-speed shaft into the gear mesh of
the low-speed gear as the shaft nears final position .
Figure 17 — 1A Shaft
b .
DOUBLE REDUCTION
— Lower high-speed shaft
assembly, Ref . #1A, Figure 17, into housing and tip
away from other bores . Simultaneously lower the
intermediate shaft assembly, Ref . #2A, Figure 19,
and the low-speed shaft assembly, Ref . #4A, Figure
20, into the housing . As shafts approach their final
position, tip the high-speed shaft pinion into the high
-speed gear mesh, Ref . #1A4 .
