BELT INSPECTION

1. Inspect belt for hour glassing (extreme circular wear
in at least one spot and on both sides of the belt).
Hour glassing occurs when the drive train does not
move and the drive clutch engages the belt.
2. Inspect belt for loose cords, missing cogs, cracks,
abrasions, thin spots, or excessive wear. Compare
belt measurements with a new drive belt. Replace if
necessary.
3. Belts with thin spots, burn marks, etc., should be
replaced to eliminate noise, vibration, or erratic PVT
operation. See the Troubleshooting Chart at the end
of this chapter for possible causes.
