CUMMINS N14 - INSTALLATION

Installation
Install new belts on the pulley. When a drive pulley uses
two or more belts, replace the belts as a complete set.
NOTE: To prevent damage, do not roll a belt over the pulley
or pry it on with a tool.
Turn the adjusting screw to increase the belt tension.
NOTE: Belt tension can increase when the fan hub mount-
ing capscrews are tightened. Do not adjust the belt tension
to full value with the adjusting screw.
Tighten the capscrews until the fan hub is in correct
alignment with the fan hub bracket.
NOTE: Do not tighten the capscrews to full torque value.
Measure the belt tension.
Refer to the Belt Tension Chart to select the correct
gauge and tension values for the belt width.
A belt is considered used if it has been in operation for
at least 10 minutes.
