DIAGNOSIS AND TESTING (CONTINUED)
E6727 EN 07/2001 2002 Bantam
3. Rotate the tensioner pulley and check for
damage, freedom of rotation or alignment.
Install a new tensioner as necessary.
4. Inspect the area surrounding the tensioner
for lubricant or other contamination. Rectify
any leaks before installing a new tensioner. If
the tensioner is contaminated, do not attempt
to clean it as the damping mechanism inside
may be damaged. Install a new tensioner as
necessary.
5. If the tensioner meets the above criteria
proceed to test the tensioner dynamically. If
the tensioner does not meet the above
criteria install a new tensioner.
Automatic Tensioner - Dynamic Check
The automatic tensioner may be checked
dynamically as follows:
1. With the engine running, observe the
tensioner movement. The tensioner should
move (respond) when the engine is
accelerated rapidly or when the air
conditioning (A/C) clutch cycles. If the
tensioner movement is not constant without
engine acceleration or A/C clutch cycling, a
pulley or shaft is possibly bent, out of round,
or the damping mechanism inside the
tensioner may be damaged. Excessive drive
belt ride out (uneven depth of grooves in the
drive belt) may cause excessive tensioner
movement. Check the condition by installing
a new accessory drive belt.
