H. Loosen the cartridge screws and rotate the
cartridge tops to the most rearward position
attainable within the slots provided in the
cartridges.
3. ASSEMBLING OUTPUT SHAFT
A. Install bearing cones on the output shaft.
Coat the shaft and bore with an anti-sieze
lubricant prior to installation. The bore of
the bearing should be heated prior to
pressing, if a heat gun is available. Tap in
place.
B. Install the bearing cup in the lower output
bore of the housing. Coat bore and cup
with anti-sieze lubricant and tap in place.
C. Position the cam so the dwell rib is facing
the output end of the housing. (Keyways
facing rearward.)
D. Insert the output shaft/follower wheel
assembly into the housing. Be sure the
followers straddle the dwell rib during
insertion.
E. Install the upper output bearing cup in the
housing and the cup with anti-sieze
lubricant and tap into place.
F. Install both lower and upper output cartridges
with the equivalent shim thickness removed
in disassembly.
G. Tighten mounting screws.
H. If endplay exists, remove shims until there is
a small amount of drag from preloading the
bearings. In rare instances it may be
necessary to remachine the cartridges if all
shims are removed and endplay still exists.
4. SETTING THE CAM
CAUTION: This mechanism is designed to operate
with adjacent followers in close ontact along their
entire width with the surface of the cam during the
dwell period. Unless this condition is achieved by
proper installation, the mechanism will not transmit
its rated load, and furthermove, serious damage to
the cam and output shaft will occur.
A. Place the cam in dwell (Keyway facing
rearward).
B. Rotate the tops of both input cartridges
toward the output until the cam followers
touch the cam.
C. Shift the cam axially (using shims between
the housing and cartridge) until two
adjacent followers are in full contact with the
cam rib. (This will also require adjustment
to the eccentric cartridges along with the
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.
