DRIVE BELT
REMOV
AL/INSPECTION
1. Remove outer PVT cover as described in PVT
Disassembly.
2. Mark drive belt direction of rotation so that it can
be installed in the same direction. NOTE:
Normally positioned so part numbers are easily
read.
3. To remove drive belt, apply brake, pull upward
and rearward on belt to open driven clutch
sheaves, pull out and down on belt to slip over the
driven clutch outer sheave.
Projected Belt
Width
Belt Width:
New 1.174 - 1.188²
(2.98-3.02 cm)
Wear Limit 1.125² (2.86 cm)
4. Measure belt width and replace if worn severely.
Generally, belt should be replaced if clutches can no
longer be adjusted to provide proper belt deflection.
G The top edges have been trimmed on
some drive belts. It will be necessary
to project the side profiles and
measure from corner to corner.
G Place a straight edge on each side of
the drive belt.
G Place another straight edge on top of
belt.
G Measure the distance where the side
straight edges intersect the top, as
shown in the illustration below .
5. Inspect belt for loose cords, missing cogs, cracks,
abrasions, thin spots, or excessive wear.
Replace if necessary.
6. 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.
Center
Distance
Clutch Center Distance -
10² +.1 / -.05 (254 +2.5 / -1.3mm)
Belt Nominal Length - 40.875²± 3/16
(103.8 cm ± .48 cm)
7. Measure belt length with a tape measure around
the outer circumference of the belt. Belts which
measure longer than nominal length may require
driven shimming or engine adjustment for a
longer center distance to obtain proper belt
deflection. Belts which measure shorter than
nominal length may require driven shimming or a
shorter center distance. Remember, proper belt
deflection is the desired goal -- not a specific
center distance.
