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.
