Troubleshooting Checklist (continued)
Possible Problem Recommended Action
7. Poor Overall Life A. Rigid Mounting
Rigid mounting of the rectangular backing plate will cause
binding between the hubs and the shaft/output assembly. The
backing plate is designed to serve as a torque arm and should
not be rigidly mounted. Re-mount the unit to allow for some
axial play between the mounting plate and mounting pin. (See
Section 2)
B. Incorrect Bearing Support
Incorrect bearing support or sideloading of the input hub can
cause excess wear. (See Section 2)
C. Excessive side loading
See incorrect bearing support above. (See Section 2)
