EVERY 10 HOURS OR DAILY
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.
