3-9. V-Belt, Missing or Broken. Some vehicle subsystems are driven by V-belts. Most liquid cooling system coolant
pumps and fans for moving air over or through a radiator require V-belts. Power generation is also belt driven. Worn or
frayed V-belts can slip or break causing the system to fail. V-belts can be replaced or substituted to restore system
Degraded output. Frequent adjustment may be required for substitute V-belts.
1 soldier/.25-1.0 hours.
Adjustable link V-belts
Rope (item 12, appx c)
Wire (item 33 or 34, appx c)
Rope or wire can also be used but thin wire must be braided to ensure the needed friction is
Assembly the rope or wire as close as possible to the original length of the correct belt.
Adjust with the tensioner assembly.
Separable-link belts can be used, if available.
Assemble the belting as close as possible to the original length of the correct belt and adjust with a
vehicle belt tensioner.
Install the belt as shown (figure 3-1). This prevents undue strain on the belt links. Belt data is
