Component Tests
Manual Belt Tensioner and Idler Pulley(s)
The manual belt tensioner and idler pulley(s) may
be checked as follows:
1. Detach the accessory drive belt in the area of
the belt tensioner or idler pulley(s).
2. Rotate the belt tensioner pulley or idler
pulley(s) and check for damage, freedom of
rotation or alignment. Install a new belt
tensioner or idler pulley(s) as necessary.
3. Inspect the area surrounding the belt
tensioner or idler pulley(s) for lubricant or
other contamination. Rectify any leaks before
installing a new belt tensioner or idler
pulley(s). If the belt tensioner pulley or idler
pulley(s) is contaminated, do not attempt to
clean it as the bearing inside may be
damaged. Install a new belt tensioner or idler
pulley(s) as necessary.
Automatic Tensioner - Static Check
The automatic tensioner may be checked
statically as follows:
1. Detach the drive belt in the area of the
tensioner.
2. Using the correct tool, move the tensioner
from its relaxed position through its full stroke
and back to the relaxed position to make
sure there is no stick, grab or bind, and to
make sure there is tension on the tensioner
spring.
