Inspecting and Replacing the Drive Belt
Read the “Maintenance and Repair Safety” section prior to
performing any work on the system (beginning on page 47).
Wear appropriate Personal Protective Equipment and follow all
industry standard safety practices.
Check the drive belt for evidence of glazing, cracks, missing or damaged ribs or
damage to the belt edges and surface. If the drive belt is damaged, install a new
drive belt.
Inspect both pulleys and the idler for damage. If any of the components show
cracks, chipping, impact damage or any other indications of physical damage,
replace the component.
If the damage indicates possible misalignment, check the pulley alignment. If
the pulleys are not properly aligned, check all fasteners to ensure that they are
properly torqued and that there are no loose or worn components.
