DRIVE BELT
Belt Removal
1. Remove outer clutch cover as described in the “PVT
Disassembly” section.
2. Mark the drive belt direction of rotation so that it can be
installed in the same direction.
NOTE: Belt is normally positioned so that the part
number can be easily read.
3. To remove drive belt, place the transmission in “Park” and
push down on the belt firmly to open the clutch sheaves.
4. Then lift upward on the belt while pulling it out and down
over the driven clutch outer sheave.
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.
Belt Installation
NOTE: Be sure to position belt in the same position
as when removed or so part number is easily read.
1. Loop belt over the drive clutch and over top of the driven
sheave.
2. While pushing down on top of belt, turn the back, or
moveable driven sheave, clockwise.
3. The belt then should be able to be pushed down into and
between the sheaves.
4. Continue rotating the driven clutch and belt clockwise until
the belt is fully installed.
PVT Break-In (Drive Belt / Clutches)
A proper break-in of the clutches and drive belt will ensure a
longer life and better performance. Break in the clutches and
drive belt by operating at slower speeds during the 10 hour
break-in period as recommended (see Chapter 3 “Engine
Break-In Period” for break-in example). Pull only light loads.
Avoid aggressive acceleration and high speed operation during
the break-in period.
