DRIVE BELT AND SPROCKET

GENERAL
Inspect the drive belt and rear sprocket:
●
At the 500 mile (800 km) service interval.
●
At every 5000 mile (8000 km) service interval thereafter.
NOTE
When a drive belt is replaced for any reason other than stone
damage, it is recommended that the transmission and rear
sprockets also be replaced to increase the longevity of the
new drive belt. In the case of stone damage, inspect sprock-
ets for damage and replace as required.
INSPECTION
Rear Sprocket
NOTE
If chrome chips or gouges to rear sprocket are large enough
to be harmful, they will leave a pattern on the belt face.
1. Inspect each tooth of rear sprocket for:
a. Major tooth damage.
b. Large chrome chips with sharp edges.
c. Gouges caused by hard objects.
d. Excessive loss of chrome plating (see Step 2).
2. To check if chrome plating has worn off, drag a scribe or
sharp knife point across the bottom of a groove between
two teeth with medium pressure.
a. If scribe or knife point slides across groove without
digging in or leaving a visible mark, chrome plating
is still good.
b. If scribe or knife points digs in and leaves a visible
mark, it is cutting the bare aluminum. A knife point
will not penetrate the chrome plating.
3. Replace rear sprocket if major tooth damage or loss of
chrome exists.
1-26 2002 Buell S3T: Maintenance
Drive Belt
See Figure 1-27. Inspect drive belt for:
●
Cuts or unusual wear patterns.
●
Outside edge bevelling (8). Some bevelling is common,
but it indicates that sprockets are misaligned.
●
Outside ribbed surface for signs of stone puncture (7). If
cracks/damage exists near edge of belt, replace belt
immediately. Damage to center of belt will require belt
replacement eventually, but when cracks extend to edge
of belt, belt failure is imminent.
●
Inside (toothed portion) of belt for exposed tensile cords
(normally covered by nylon layer and polyethylene layer).
This condition will result in belt failure and indicates worn
transmission sprocket teeth. Replace belt and transmis-
sion sprocket.
●
Signs of puncture or cracking at the base of the belt
teeth. Replace belt if either condition exists.
●
Replace belt if conditions 2, 3, 6 or 7 (on edge of belt)
exist.
NOTE
Condition 1 may develop into 2 or 3 over time. Condition 1 is
not grounds for replacing the belt, but it should be watched
closely before condition 2 develops which will required belt
replacement.
CLEANING
Keep dirt, grease, oil, and debris off the belt and sprockets.
Clean the drive belt with a spray solution of mild soap and
water. Wipe the solution off the belt and dry. Do not immerse
the belt in the soapy water solution.
