ON–VEHICLE INSPECTION
1. INSPECT DRIVE BELT INSTALLATION CONDITION
Check that the drive belt fits properily in the ribbed grooves.
2. INSPECT DRIVE BELT DEFLECTION
Using a belt tension gauge, apply load of 98 N (10 kgf, 22 lbf)
and measure drive belt deflection.
Drive belt deflection:
New belt: 11 – 13 mm (0.47 – 0.51 in.)
Used belt: 15 – 18 mm (0.59 – 0.71 in.)
HINT:

”New belt” refers to a belt which has been used less than
5 minutes on the running engine.

”Used belt” refer to a belt which has been on a running en-
gine for 5 minutes or more.

After installing the drive belt, check that it fits properly in
the ribbed grooves.
3. INSPECT DRIVE BELT TENSION
Using a belt tension gauge, check the drive belt tension.
Drive belt tension:
New belt: 520 – 755 N (53 – 77 kgf)
Used belt: 196 – 392 N (20 – 40 kgf)
