6. With a ½ ” bolt, drive the bolt into one of the three ½ -13
UNC threaded holes. This will break the seal between
the housing and the maincase allowing the removal of
the assembly.
NOTE : Special care should be taken when removing
the output assembly. All gearing is stabilized at the
output assembly. Removing output assembly first may
result in difficulties during reducer reassemby. It is
recommended that the input assembly be removed
first, then the gear train, and finally the output assembly
(reference Section 6.5 for additional information).
7. Remove assembly by lifting it straight up away from the
maincase. An eye bolt can be used in the threaded end
of the shaft to lift the assembly; reference Figure 6.3.1.
DO NOT LIFT ENTIRE REDUCER BY THE THREADED
HOLE ON EITHER SHAFT.
NOTE : Place all removed parts on a clean dry surface
to avoid contact with contaminants.
CAUTION : Do not lift input or output shaft assembly by
hand. The assemblies are heavy and lifting by hand can
cause serious injury.

9. With an arbor press or a hydraulic press, press on
the inboard end of the shaft to break free the inboard
bearing cone.
10. At this time, the shaft will be free and can be separated
from the housing. The inboard bearing cone will be
free to remove and discard.
CAUTION : The input and output shafts are heavy.
11. To remove the outboard bearing from the shaft, one
of two procedures can be used. 1.) Support the shaft
by the bearing cone with the inboard end of the shaft
facing up. With an arbor press or hydraulic press,
press down on the inboard end of the shaft; reference
Figure 6.3.2.2. 2.) With a hammer and punch, carefully
strike the bearing cone towards the inboard end of the
shaft; reference Figure 6.3.2.3.
