DIAGNOSIS AND TESTING
Accessory Drive
lnspection and Verification
1. Verify the customer concern.
2.
Visually inspect for obvious signs of mechanical
damage.
Visual lnspection Chart
I Mechanical I
- Damaged or contaminated accessory drive
belt
- Damaged or contaminated pulley(s)
- lncorrect accessory drive belt
- lncorrect fitment of the accessory drive belt
- Accessory drive belt tensioner
- Accessory drive belt idler pulley
- Generator
- Power steering pump
- Power steering pump leakage
- Air conditioning (AIC) compressor
- 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.
Accessory Drive Belt Concerns
A CAUTI0N:Do not lubricate the accessory
drive belt, accessory drive belt tensioner
or idler
pulley(s) as potential damage to
the accessory drive belt material
construction, accessory drive belt
tensioner damping mechanism, accessory
drive belt tensioner pulley bearing and idler
pulley(s) bearing may occur.
Cracking
Accessory drive belts are made from rubber which
hardens with time and can
develop cracks. As the
belt runs on the back of some of the pulleys, the
cracks are opened up.
Small cracks are not
considered to be a
failure of the belt. Only if the
,crack is deep enough to reach the bottom of the
grooveto expose the cord or any chunks are found
to be missing from the
belt, is the belt condition
considered to be
unacceptable.
1. Check the accessory drive belt for cracks. If the
damage exceeds the
acceptable limit, install a
new accessory drive
belt.

3. Check the accessory drive belt for pilling. The (.
condition of the belt should be compared against
the
illustration.
1. Small scattered pills. Not considered a
concern. No action required.
Pilling 2. Small scattered pills. Not considered a ,
concern. No action required. Pilling is dust that forms in between the ribs of the
belt from rubber that is worn off the belt when it is
new. There may
also be loose particles left on the
belt during the manufacturing process. These are
worn off and form into
small balls of rubber that
then get trapped in the grooves of the
belt. This
condition
will usually clear itself within 4800 km -
8000 km (3000 miles - 5000 miles) of normal
driving.

0212003
Due to the manufacturing process, the belt edge
may appear frayed, but this frayed appearance
does not
necessarily affect the durability or
performance of the
belt. If a concern is raised
during a service or repair over the
level of fraying,
the condition of the
belt should be compared
against the
illustrations.
