ASSEMBLY
1. PRIOR TO ASSEMBLY
A. Clean and deburr all parts before reas-
sembling.
B. Follow tightening torque and loctitie
recommendations as outlined in the
"General Service Manual".
2. INPUT SHAFT/CAM REASSEMBLY
A. Install key (23) on input shaft (4).
B. Apply anti-seize lubricant to both input
shaft (4) and the bore of cam (3).
C. Preposition the cam on the shaft so that
the keyway in the cam lines up with key
(23).
D. Use an arbor press to press the shaft
into the cam.
E. Install spacer (27) on shaft (4).
F. Apply anti-seize lubricant to both input
shaft (4) and the bores of bearing cones
(14).
G. Use an arbor to press bearing cones
(14) onto input shaft (4).
NOTE: CAMCO recommends heating
the bearing cone with a heat gun, if
available, prior to installation onto the
shaft.
3. OUTPUT SHAFT/FOLLOWER WHEEL
REASSEMBLY
A. Apply anti-seize lubricant to both fol-
lower wheel (2) and the bore of bearing
(7).
B. Install bearing (7) onto follower wheel (2)
until seated.
C. Install screws (21) with washers (22)
using loctite thread locking liquid as
recommended in the ‘’General Service
Manual‘’.
CAUTION: Be sure to press the follower in
straight as damage to the
follower and wheel could occur
if improperly aligned during
installation.
D. Align the notch on the stud of follower
(19) with the tapped hole for setscrew
(26). Press in the follower using an
arbor press.
NOTE: 1/2 inch diameter followers must
be pressed in until the face of the fol-
lower is 0.522 inch above the face of
follower wheel (2).
E. Install set screw (26) using loctite thread
locking liquid as recommended in the
‘’General Service Manual‘’.
F. Install remaining followers (19) in the
same manner.
4. INSTALLING NEW BEARING CUPS
A. Coat the outside of bearing cups (15)
and the bores of cartridges (5) with an
anti-seize lubricant.
B. Use an arbor to press the bearing cups
into the cartridges.
5. SETTING INPUT SHAFT/CAM BEARING
PRELOAD
A. Position housing (1) on a work bench
with the bore for plug (32) facing down
and the bore for follower wheel (2)
toward you.
B. Install one cartridge (5) in the same side
and position as disassembled (See
matchmark instructions of Output Shaft/
Follower Wheel Removal). Be sure to
install the same exact shims or equiva-
lent thickness as was removed during
disassembly.
C. Install and tighten screws (16).
D. Insert the input shaft/cam (4) into hous-
ing (1) so that orientation of shaft is the
same as before disassembly.
E. Install remaining cartridge (5) in the
same position as disassembled (See
matchmark instructions of Output Shaft/
Follower Wheel Removal). Be sure to
install the same shims or equivalent
thickness as was removed during disas-
sembly.
