Wheel Drive Belt and Wheel Hub

Replacement - Gear Drive

The following inspections should be made when disas-

sembling the drive system, particularly if the reason for

service is the inability to adjust belt tension or “loss of

drive”. Be sure to inspect all components; there may be

more than one item needing replacement.

Inspect for the following:

• Pulley ﬂ anges bent or damaged. They can pinch or

cut the belt.

• Idler arm bent - this will push the belt to one side and

can induce belt jumping in reverse.

• Idler pulley bearing worn out, resulting in

inconsistent tension on the belt. Can cause slippage

or jumping.

• A belt contacting the bottom of the pulley “V”

indicates worn belt or pulleys. The belt will slip no

matter how tight you adjust it.

• Belt glazed, shiny or burnt on the sides of the “V”

indicates slipping. Belt must be replaced and the

cause identiﬁ ed and corrected.

• The sides of each pulley sheave should be straight

and ﬂ at. If the sides of the “V” have “opened up”

or appear to bulge the pulley is worn and must be

replaced.

If the belt is riding too deep in one or both pulley grooves

the center ﬂ ange will begin to cut the belt into 2 single

belts. This indicates a badly worn belt or pulley. The

parts must be replaced.

19. Check the parking brake. Refer to “Checking the

Parking Brake” on page 3-14.
