Cracks on the rib side of a belt are considered acceptable. If the
belt has chunks missing from the ribs, it should be replaced.

Check the drive belt deflection by pressing on the belt at
the points indicated in the illustration with 98 N (10 kgf, 22
lbf) of pressure.
Drive belt deflection:
New belt 5 -- 7 mm (0.20 -- 0.28 in.)
Used belt 7 -- 8 mm (0.28 -- 0.31 in)
If necessary, adjust the drive belt deflection.

Belt tension gauge:
Denso BTG--20 (95506--00020)
Borroughs No. BT--33--73F
Drive belt tension:
New belt 520 -- 750 N (53 -- 77 kgf)
Used belt 295 -- 392 N (30 -- 40 kgf)
If the belt tension is not as specified, adjust it.
