Checking the Condition of the Belt
Service Interval: Every 250 hours
1. Remove the right-side panel; refer to
Side Panels (page
45).
2. Inspect the belt for cuts, cracks, loose cords, grease, oil,
twisting, or signs of abnormal wear.
Note: Replace the belt if it is excessively worn or
damaged; refer to

Removing the Belt
1. Remove the right side panel; refer to
Side Panels (page
45).
2. Loosen the tension on the belt by rotating the belt
tensioner clockwise
Important: The belt tensioner is spring loaded
and must pivot away from the drive belt. Pivoting
the belt tensioner in the wrong direction could
damage it. Also, do not use excessive force in
the opposite direction of windup or after you
have wound up the tensioner to the positive stop;
otherwise, the tensioner arm may break.

Cleaning and Inspecting the Belt and
the Pulleys
1. Inspect the belt for excessive wear and damage.
Replace the belt under any of the following conditions:
•
The belt is frayed, punctured, or some of its
material is missing.
•
There is embedded debris in the grooves or on the
backside of the belt.
•
The ribs are uneven or excessively worn.
•
The backside of the belt is glazed from high heat.
•
There are exposed belt cords.
Note: You can reuse a belt with transverse cracks
(across the belt) are acceptable, but replace a belt with
longitudinal cracks (in the direction of the ribs) that
intersect with transverse cracks.
2. Clean the idler and the drive pulleys, and inspect them
for wear or cracks.
Note: Replace any pulleys that are damaged,
deformed, or excessively worn.
Installing the Belt
1. Route the belt onto the pulleys, but do not install the
belt over the belt tensioner
2. Rotate the belt tensioner clockwise and install the belt
by slipping the belt over the belt tensioner.
3. Slowly release the belt tensioner to apply tension to
the drive belt.
4. Ensure that the belt is aligned with the belt tensioner
and in the grooves of the pulleys.
