ASSEMBLY
PRIOR TO REASSEMBLY
Clean and deburr all parts before reassembly.
Follow tightening torque and Loc-tite ™
recommendations as outlined in the General
Service Manual.
1. Use an arbor press to press bearing cups
into input cartridges. Coat outside of cup
and the cartridge bore with anti-sieze
lubricant prior to pressing. Fill cavity of
cartridges with bearing grease
recommended in the “General Service
Manual”.
2. ASSEMBLING INPUT SHAFT.
A. Use arbor to press cam onto shaft. Be sure
key is installed into shaft. Apply anti-seize
lubricant on shaft and cam bore prior to
pressing.
B. Center cam on shaft.
C. Use an arbor to press bearing cones
ontoshaft. Coat shaft and bearing bore with
anti-sieze lubricant prior to pressing.
D. Install the input cartridges. Be sure to install
the same exact shims or equivalent height
as removed during disassembly.
E. Line up match marks.
F. Tighten cartridge mounting screws.
G. If endplay exists remove an equal amount of
shims from each side until there is a small
amount of drag (1 to 2 inch ozs.) from
preloading the bearings. In rare instances it
may be necessary to remachine the
cartridges if all shims have been removed
and endplay still exists.
the housing by the same method as
described in step “A”.
8. INPUT SHAFT/CAM REMOVAL.
NOTE: The output shaft must be removed prior to
input shaft removal.
A. Rotate the input shaft and inspect all parts
for wear or damage. Endplay in the input
shaft is not permissible.
B. Match mark both input cartridges relative to
the housing. These must be reinstalled in
the same side and position since they are
eccentric.
C. Remove all input bearing cartridge
capscrews.
D. Tap on end of input shaft to drive the
opposite cartridge from the housing. Then
drive the shaft in the opposite direction for
removal of the remaining cartridge.
NOTE: Keep the shims with their respective
cartriges. You will be asked to reinstall or replace
the same shim thickness during reassembly.
E. Use a wheel puller to remove one bearing
cone from the input shaft.
