10. REMOVING SHAFT FROM OUTPUT
ASSEMBLY.
To remove the output shaft from the cover it will
be necessary to use an arbor press and
push from the back side of the shaft using
caution not to damage the parts.
Fig. 4 Pressing out shaft.
11. REMOVAL OF BEARINGS.
A. Use a wheel puller to remove the cone
portion of bearing from the shaft.
B. Removal of the upper bearing cup from the
output cover will require light tapping on the
backside of the cup with a round aluminum
bar and a hammer working around the
perimeter as you tap to prevent binding.
Continue this procedure until the cup is free
of the cover.
C. Removal of the lower output bearing cup
from the output cover requires prying from
the backside or drilling and tapping of jack
screw holes or the use of a pulley puller.
12. INPUT SHAFT REMOVAL.
NOTE: The output shaft must be removed prior to
input shaft removal
A. Rotate the input shaft and inspect all parts
for damage. Endplay in the output shaft is
not permissaable.
B. Remove all input bearing cartridge
capscrews.
C. Tap on the end of the input shaft to drive the
opposite cartridge from the housing. Then
drive the shaft in the opposite direction for
removal of other cartridges.
NOTE: Keep shims with their respective cartridges
you will be asked to reinstall or replace with the
same shim thickness during assembly.
D. Remove the input shaft/cam assembly
through the large cartridge hole (does not
apply to 662RA see Step E).
E. The 662RA requires removal of the cam
locknuts while still in the housing and
pressing the shaft through the hole
previously occupied by the input cartridge
and removed in Step C. This will
automatically remove the bearing cone from
one end of the input shaft. The use of an
arbor press is recommended but this
procedure can be accomplished by driving
the shaft through with a soft faced hammer.
F. Remove cam through the output opening.
13. REMOVAL OF CAM FROM OUTPUT SHAFT

cones from the input shaft.
