in an oven Insert key, Ref #2A4, in shaft keyway
Assemble gear onto shaft, with the chamfer toward
pinion, using a press to ensure a tight fit Allow
gear to cool before proceeding
b Assemble spacer, Ref #2A6, onto intermediate
shaft (except sizes 5307 and 5315) Seat bearings
or cones, Ref #2A1 & 2A2, on shaft Seat all

BEARING ADJUSTMENT
a
SIZES 5107 THRU 5315 —
Bearing adjustment is
made by adjusting thickness of metal shims, Ref
#24, behind bearing cups in input housing, Ref
#10
NOTE: The thickest shim should be located
adjacent to the bearing cup The thinnest shims
should be located in the center of the shim pack
(1) Support input housing, such that when high-
speed shaft assembly, Ref #1A or 3A, is
lowered into place there is clearance for shaft
extension end Install bearing cups in input
housing without any metal shims Tap dowel
pins into input housing with solid pin nearest
high-speed shaft bore
(2) Lower low-speed shaft assembly, Ref #4A,
into input housing, Ref #10, with threaded
end facing up (DO NOT install Ref #1A [or 3A]
or 2A shaft assemblies at this time)
(3) Assemble output housing, Ref #11, to input
housing Install housing flange fasteners, Ref
#25, with heads of cap screws against input
housing Cross tighten fasteners to torque
specified in Table 14 )
(4) Measure low-speed shaft axial float with a
dial indicator, in accordance with method
described on the following page
