Removal
FIG. 98: Before Removing or Installing any drive belts.
Lower the header to the ground.
Remove the starter key.
Engage the parking brake.
Disconnect the battery at battery switch.
Raise or remove shields or guards and locate the guards
away from the drive so that the guards do not cause
problems with working on the drive.
Loosen tensioner until the belt is slack and can be
removed without prying. Never pry off a belt, as the
sheave can be damaged. Prying off belts also adds risk of
injury.
Inspect the old belt for any not normal wear. Excessive or
not normal wear can indicate problems with the drive or
past maintenance procedures. Refer to the Belt Problem
and Wear Guide.
Inspect the sheaves for not normal or excessive wear,
damage, distortion, and pitting. If surfaces show pitting or
excessive wear, the sheave must be replaced.
Check the sheaves for deposits of dirt and dust in the
bottom of the grooves. Clean sheaves with a damp cloth.
Do not sand or scrape the grooves to remove debris.
Installation
Check the sheave alignment. For long belt life the
sheaves must be aligned properly.
FIG. 99: Order a new belt by the part number, not by
measuring the old belt.
Time must be taken to make sure the selection of the
proper size belts for the different sheaves is correct.
