4. Remove bore plug (Item #33), the cam
follower screw (Item #15) and the heavy
washer (Item #9). CAMCO used Red
Perma-Lok‚ to secure these screws If
you encounter difficulty when removing
the screw, apply heat to the screw and
remove while still warm.
CAUTION
Localized heat can distort the part. Do not
overheat any item.
5. Using a large soft faced hammer, drive
the cam follower downward and out
through the follower wheel.
6. Inspect each cam follower stud hole for
roundness and size. The cam follower
stud hole must be a interference fit. The
cam follower holes must be -.0005 to -
.0010 inch for the full length of the hole.
Check the follower holes for roundness.
These holes should be round within .0005
TIR of an inch to permit reuse of the
follower wheel. These holes may be
worn-out due to overloads.
CAUTION
Do not use a follower wheel with oversize fol-
lower holes. The cam followers and cam will
fail prematurely.
CAM FOLLOWER INSTALLATION:
The instructions for replacing cam followers
assume the follower wheel and cam were not
removed. Cam followers will be installed one
at a time through the follower access hole in
the housing. If the follower wheel was
removed, proceed by repeating the first four
steps until all cam followers have been
installed in the follower wheel.
If the cam was removed but not the follower
wheel, proceed by repeating the first four
steps until all but two cam followers have
been replaced. Also see additional instruc-
tions below.
WARNING
Use protective gloves while handling cam fol-
lowers after they have been packed in dry ice.
1. Coat the follower wheel stud hole with
anti-seize lubricant. Using quick sure
movements, place a cam follower that
has been packed in dry ice for at least
three (3) hours into the follower wheel
hole.
1.1. Using a twisting motion of the hand,
push the cam follower upward hard
enough to press the cam follower into
the follower wheel hole. Make sure the
shoulder on the cam follower seats
against the follower wheel. Do not
rush the process; just proceed quickly
and with sure movements.
1.2. If the cam follower cannot be seated
by using a twisting motion of the hand
and pushing upward, use a soft faced
hammer to drive the cam follower into
the follower wheel.
1.3. Alternatively, pull the cam follower
into place using the cam follower
screw, heavy washer and tapped hole
in the cam follower stud.
1.4. In a worst case, place a steel plate
against the bottom of the cam follower
and use a hydraulic jack to push the
cam follower into the follower wheel.
CAUTION
Make sure the shoulder of the cam follower is
seated against the follower wheel and make
sure the follower is installed straight and in
line with the hole. Damage to the cam
follower, follower wheel or cam could occur if
cam follower is improperly aligned during
installation.
