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.
13. Bend over the lockwasher tabs towards
the locknut and into the slot.
CAUTION
A torque specification for locknuts is not avail-
able. Make sure they are tight!

locknuts on the opposite side of the cam.
15. After tightening locknuts, re-apply
Prussian Blue and check for tip relief etc.
FOLLOWER WHEEL AND/OR
OUTPUT BEARING REPLACEMENT:
FOLLOWER WHEEL REMOVAL:
In most cases, the follower wheel and/or out-
put bearing cannot be removed without
removing the major portion of any support
structure and fixtures. An overhead crane or
similar device must be used to lift the follower
wheel and output bearing. In some cases, the
support structure and fixtures can be lifted
two to three feet above the unit and support-
ed by appropriate scaffolding. The follower
wheel and output bearing can then be
removed with a boom crane or similar device.
CAMCO recommends using professional
machinery riggers for this purpose. The
assistance of a CAMCO trained serviceman
is recommended.
1. Use the motor drive package to position
the input shaft keyway such that the cam is
just entering dwell.
Note: For most Camco E-Series Index Drives
this is ten to fifteen (10˚ - 15˚) degrees clock-
wise or counter-clockwise from the mid-dwell
position.
