DRIVE BELT
ON-VEHICLE INSPECTION
1. INSPECT DRIVE BELT'S INSTALLATION CONDITION
Check that the drive belt fits properly in the ribbed grooves.
2. INSPECT DRIVE BELT TENSION
Using a belt tension gauge, check the drive belt tension.
Belt tension gauge:
Nippondenso BTG-20 (95506-00020) or Borroughs
No. BT-33-73F
Drive belt tension:
New belt 160 ± 25 lbf
Used belt 100 ± 20 lbf
HINT:
ºNew beltº refers to a belt which has been used less than
5 minutes on a running engine.
ºUsed beltº refers to a belt which has been used on a run-
ning engine for 5 minutes or more.
After installing the drive belt, check that it fits properly in
the ribbed grooves.
