DIAGNOSIS AND TESTING
E6727 EN 07/2001 2002 Bantam
Accessory Drive
Inspection and Verification
1. Verify the customer concern.
2. Visually inspect for obvious signs of
mechanical damage.
Visual Inspection Chart
Mechanical
• Cracked, damaged or contaminated accessory
drive belt
• Belt tension
• Belt tensioner
• Idler pulley(s)
• Pulley(s)
• Loose hardware
3. If an obvious cause for an observed or
reported concern is found, correct the cause
(if possible) before proceeding to the next
step.
CAUTION: Do not lubricate the belt, belt
tensioner or idler pulley(s) as potential
damage to the belt material construction;
belt tensioner damping mechanism, belt
tensioner pulley bearing and idler
pulley(s) bearing may occur.
NOTE:
Up to 15 cracks in a belt rib over a
distance of 100 mm may be considered
acceptable. If the cracks exceed the acceptable
limit or any chunks are found to be missing,
install a new belt.
4. The condition of the belt should be compared
against the illustration and appropriate action
taken.
Small scattered deposits of rubber debris is not a
concern and therefore a new belt should not be
installed.
Longer deposits of rubber debris building up to
50% of the belt rib height is not a concern but
may result in excessive noise. If excessive noise
is apparent, install a new belt.
Heavy deposits of rubber debris building up along
the grooves is a concern and may result in
excessive noise and a belt stability concern. If
heavy deposits or excessive belt noise are
apparent, install a new accessory drive belt.
