PVT BREAK-IN (CLUTCHES / BELT)
A proper break-in of the clutches and drive belt will ensure a longer life and
better performance. Break in the clutches and belt by operating at slower
speeds during the break-in period as recommended. Pull only light loads. Avoid
aggressive acceleration and high speed operation during the break-in period.
If a belt fails, always clean away all debris when replacing the belt.
DRIVE 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 General Diagnostic information for
possible causes.
