8.1. Installation tools should have an out-
side diameter .010 inch smaller than
the bore size. The bore should be
.005 larger than the shaft size, and the
face of the tool should be relieved so
that pressure is applied only near the
outside diameter of the seal.
8.2. During installation press the seal
flush to the cartridge face to avoid
cocking the seal in the bore. This also
positions the seal correctly on the
shaft.
9. When an installation tool cannot be man-
ufactured, install the seal by tapping uni-
formly around the seal with a soft ham-
mer. Avoid cocking the seal and make
sure the face of the seal is square to the
bore.
CAM FOLLOWER REPLACEMENT:
CAM FOLLOWER REMOVAL:
Instructions for replacing cam followers
assume the cam and follower wheel will not
be removed. If the follower wheel will be
removed, proceed to the section titled
"Follower Wheel and/or Output Bearing
Replacement" in this Service Manual.
Likewise, if the cam will be removed, proceed
to the section titled "Cam and/or Input Shaft
Replacement" in this Service Manual.
Otherwise, proceed with the following steps.
If the machine builder has provided access to
the cam follower screws, the tooling does not
have to be removed. Otherwise the support
structure and fixtures can be removed as nec-
essary, or the support structure and fixtures
can be lifted two to three feet above the unit
and supported by appropriate scaffolding.
CAMCO recommends using professional
machinery riggers for this purpose. The
assistance of a CAMCO trained serviceman
is recommended.
At least three (3) hours before installing new
cam followers, pack all new cam followers in
a large Styrofoam container (Igloo‚ 50 or 60
gallon Ice Chest) three-quarters filled with dry
ice.
1. Remove socket head cap screws
(Item # 32) and remove side access
cover (Item #10)
2. Once this cover is removed you may
view inside to locate the follower access
cover (Item #9). Remove the socket head
cap screws (Item #25) and remove this
cover.

3. Use the motor and drive package to
rotate the input shaft and follower wheel
until a follower is positioned directly
above and centered on the removal
opening.
WARNING
CAMCO’s Heavy Duty "E" Series Index Drives
cannot be "hand cranked" when completely
assembled, i.e. with follower wheel installed.
During some portions of repair, the motor
drive package is used to rotate the input shaft
and follower wheel. Some means for running
the motor at extremely low speeds is manda-
tory. Use extreme caution when operating the
motor during repairs.
