NOTE: When reinstalling the belt with the drive clutch
and driven clutch already removed follow these steps:
Install the driven clutch.
S
Install the belt onto the driven clutch.
S
Loop the drive clutch through the
S
belt.
Install the drive clutch onto the
S
crankshaft.
4. Measure belt width and replace if worn.
Generally, belts should be replaced if clutches
can no longer be adjusted to provide proper belt
deflection.
The top edges have been trimmed on
S
some drive belts. It will be necessary
to project the side profiles and
measure from corner to corner.
Place a straight edge on each side of
S
the drive belt.
Place another straight edge on top of
S
belt.
Measure the distance where the side
S
straight edges intersect the top, as
shown in the illustration.
Projected Belt
Width
Belt Width:
New 1.174 - 1.188" (2.98-3.02 cm)
Wear Limit 1.125" (2.86 cm)
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 continuously in one spot.
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.
8. Replace belt if worn past the service limit. Belts
with thin spots, burn marks, etc., should be
replaced to eliminate noise, vibration, or erratic
PVT operation. See Troubleshooting Chart at the
CLUTCH
