OPERATION 3

Check the Fan Belt Tension

The QSM11 and N14 engines use a spring-loaded idler, 1, (N14 illustrated) to keep a constant tension on the fan belt. No adjustment is required. If the belt is not tight, check the pivot of the spring-loaded idler for binding. If it is free, the belt is probably worn out and requires replacement.

If the belt requires replacement, install a square end of a 95mm (3/8) breaker bar into the slot of the idler and release the spring tension by pushing down on the wrench. Slip the old belt off the engine pulleys and install a new belt. Release the wrench and allow the spring-loaded idler to apply belt tension.

NOTE: Refer to your Cummins Engine Manual for more information regarding belt replacement, wear guidelines, and pulley alignment.

NOTE: Fan drive belts are supplied by Buhler Versatile. Contact your Buhler Versatile dealer if a new fan belt is required.
