B. Install the bearing retainer capscrews and
washers. Use torque and Loc-Tite
recommendations from the “General
Service Manual”.
C. Install new followers with an arbor press.
CAUTION: Be sure to press the followers in straight
as damage to the follower and wheel could occur if
improperly aligned during installation. Be sure that
the notches are aligned with the setscrew holes.
Fig. 8 Pressing in new followers
D. Install the setscrews with double-notch
followers, the cone point setscrews lock into
the “V” notch. The cup point setscrews lock
against the flat single-notch followers, use
an oval point setscrew. Be sure to use Loc-
tite thread locking liquid as recommended in
the “General Service Manual”.
E. Coat the inside of the bearing retainer ring
and the outside of the main output bearing
with anti-sieze lubricant. Place the bearing
retainer ring over the output from the
topside of the output/follower wheel and tap,
alternating from side to side until the
retainer is fully seated on the bearing.
F. Replace the shims removed in disassembly
step 4C.
G. Place cam in dwell position, keyway pointing
rearward.
H. Insert output/follower wheel into housing
with dowel holes in housing in line with
retainer.
I. Loosely install the bearing retainer
capscrews.
J. Install only one of the dowel pins through the
retainer ring into the housing.
4. SETTING THE CAM.
CAUTION: This mechanism is designed to operate
with adjacent followers in close contact along their
entire width, unless this condition is achieved by
proper installation, the mechanism will not transmit
its rated load,and serious damage to the cam and
output shaft will occur.
A. Place the unit on end or its side so both the
output side and the bottom opening are
accessible.
B. Place the cam in dwell, keyway facing
rearward.
C. While pivoting on the one dowel pin, rotate
the output towards the input shaft as much
as the clearance holes for the mounting
capscrews will allow.
D. Shift the cam axially until two adjacent
followers are in full contact with the cam rib.
This will also require adjustment of the
output retaining ring along with axial
adjustment of the cam.
1) If there is a gap at the root of the
follower the cam should be shifted
toward the follower.
2) If there is a gap at the tip of the follower
the cam should be shifted away from the
follower.
