TM 9-2320-356-BD
Section III. BELTS
3-8. GENERAL
V-Belts provide direct drive and can be substituted or replaced if the basic
factors about each belt are considered.
Substitute belts must be the correct
length to maintain tension and wide enough to prevent bottoming in the pulley V.
Inspect width and length of the belt.
Smaller, narrower belts may be substituted
or V-belts may be taken from another vehicle if there are twin belt drives.
Direct
vehicle-to-vehicle removal and installation is a simple method of replacing missing
belts.
3-9.

restore system functions.
Frequent adjustment may be required for substitute
V-belts.
