Camco 2050E, 950E, 1550E, 1150E service manual CAM Follower Installation

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.
