Drive Belt System - Buell 2007 FIREBOLT Service Manual

HOME
DRIVE BELT
GENERAL
The drive belt tension on a new belt will loosen after approxi-
mately 1000 miles (1600 km). The drive belt tension is auto-
matically determined by the idler pulley. Axle alignment is not
adjustable.
INSPECTION
Rear Sprocket
NOTE
If 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 coating chips (larger than 0.25 in.) (6.35 mm)
missing/removed.
c. Gouges caused by hard objects.
2. Replace rear sprocket if major tooth damage or loss of
coating in an area 0.25 in. (6.35 mm) or larger occurs.
1-28 2007 Buell Firebolt: Maintenance
Drive Belt
See Table 1-8. Inspect drive belt for:
Cuts or unusual wear patterns on both sides of belt.
Outside edge bevelling. Some bevelling is common, but it
indicates that sprockets are misaligned.
Outside surface for signs of stone puncture. If cracks/
damage exists near edge of belt, replace belt immedi-
ately. Damage to center of belt will require belt replace-
ment 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 facing fabric). This condition will
result in belt failure and indicates worn transmission
sprocket teeth. Replace belt and transmission sprocket.
Signs of puncture or cracking at the base of the belt
teeth. Replace belt if either condition exists.
Idler Pulley
Inspect idler pulley for signs of uneven wear. Excessive lat-
eral side play of 0.020 in. (0.5 mm) or roughness indicates
worn bearings. Replace idler pulley as an assembly. See
DRIVE BELT SYSTEM.

CLEANING

spray solution as required. Dry thoroughly. Do not immerse
belt in solution. Do not direct pressurized water on belt.
