1. Remove two or three cam followers. See
section titled "Cam Follower Removal" in
this Service Manual for detailed instruc-
tions on cam follower removal.
2. While referring to the sketch titled
"E-Series Input Shaft And Cam
Removal", proceed as follows.
3. Bend lockwasher (Item #20) tabs over
and away from locknut.
4. Loosen the locknuts (Item #19) that
secure the cam to the input shaft (Item
#3). CAMCO uses Green Perma-Lok‚ to
secure the locknuts. If you encounter dif-
ficulty, apply heat to the locknut and
remove while still warm.
CAUTION
Localized heat can distort the part. Do not
overheat any item..
4.1. Use a Spanner Wrench that has been
locked (jammed) against the top or
bottom of the housing to hold the
locknut while turning the input shaft.
Use the motor drive package to rotate
the input shaft and break loose the
locknuts.
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.
4.2. Break loose the locknuts, don’t com-
pletely loosen or remove them from the
threaded portion of the input shaft.
4.3. In some cases it might be necessary
to split the locknut before it will break
loose. Use a cold chisel or other suit-
able tool for this purpose.
5. Depending on whether the follower wheel
was removed, proceed as follows.
5.1. Follower wheel was not removed.
5.1.1. Use the motor drive package to
rotate the input shaft and rotate the
follower wheel through motion until a
position is reached where one of the
previously removed cam followers
starts to enter the cam.
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
mandatory. Use extreme caution when oper-
ating the motor during repairs.
5.1.2. Rotate the follower wheel until the
position of one removed cam follower
is directly above the tapped "lifting
hole" in the cam. See sketch titled
"E-Series Input Shaft and Cam
Removal" in this Service Manual.
5.1.3. Install threaded rod into the "lift-
ing hole" in the cam and let the
threaded rod extend beyond the top
surface of the follower wheel. Put a
hex nut on the threaded rod and run
it down until the nut is tight against
the cam. The length of the extension
should be sufficient to lower the cam
into the bottom of the housing.
5.1.4. Place a piece of plate (approxi-
mately 1/2" x 6" x 6") with a hole
through the center over the threaded
rod. This plate will act like a large
washer for supporting the cam during
removal of the input shaft. See
sketch titled "E-Series Input Shaft
and Cam Removal" in this Service
Manual.
