E. Use a wheel puller to remove the bearing
cones from the input shaft.
F.
Remove the cam locknuts with a spanner
wrench. Be sure to bend the washer locking
tangs away from the nut prior to removal, if
applicable.
G. Use an arbor press to remove the cam from
the input shaft. Use caution not to damage
the parts. If an arbor press is not available
you may drive the shaft out by tapping on
the end of the shaft with a soft face.

Remove the input bearing cups from the
cartridges with a pulley puller, by prying or
by drilling and tapping for jack screws.
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 to press the bearing cups into the
cartridges. Coat the outside of the cup and the
bore of the cartridge with an anti-seize 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 the cam onto the shaft.
Be sure key is installed into the shaft first.
Apply anti-sieze lubricant to shaft and bore
prior to pressing. If a heat gun is available it
is recommended that the bore of the cam be
heated prior to pressing.
B. Use a spanner wrench to install the cam
locknuts. Adjust nuts to center cam on
shaft.
Fig.7. Centering cam on shaft
C. Use an arbor to press bearing cones onto
shaft. Coat shaft and bearing bore with anti-
sieze lubricant prior to pressing. If a heat
gun is available it is recommended that the
bore of the bearing be heated prior to
pressing.
D. Install the input cartridges. Be sure to install
the same exact shims or equivalent height
as was removed in disassembly Step 9C.
E. Tighten cartridge mounting screws.
F.
If endplay exists remove an equal amount of
shims from each side until there is a small
amount of drag from preloading the
bearings. In rare instances it may be
necessary to re-machine the cartridges if all
shims have been removed and endplay still
exists.
3. ASSEMBLING OUTPUT SHAFT.
A. Install the large bearing cones on the output
shaft. Coat the bore of the cone with an anti-
sieze lubricant prior to installation. Tap in
place with a hammer and aluminum bar.
Place the bar against the inner face and tap
with hammer. Alternate from side to side to
avoid binding until the bearing is fully seated
on the output/follower wheel.
