4. VISUALLY CHECK ALTERNATOR WIRING AND
(a) Visually check the drive belt for cracks, oiliness or
wear. Check that the belt does not touch the bottom
of the pulley groove.
If necessary, replace the drive belt.
(b) Check the drive belt deflection by pressing on the
belt at the points indicated in the figure with 10 kg
(22.0 lb, 98 N) of pressure.
Drive belt deflection:
New belt 7.0 — 9.0 mm (0.278 — 0.354 in.)
Used belt 9.0 — 12.0 mm (0.354 — 0.472 in.)
If the belt deflection is not within specification, adjust it.
( Reference)
Using SST, check the drive belt tension.
SST A 09216-00020
SST B 09216-00030
Drive belt tension:
New belt 55 — 65 kg
Used belt 30 — 45 kg
If necessary, adjust the drive belt tension.
HINT:
• When checking the tension, be sure the gauge is on
the belt protrusion.
• "New belt" refers to a belt which has been used less
than 5 minutes on a running engine.
• "Used belt" refers to a belt which has been used on a
running engine for 5 minutes or more.
• After installing the belt, run the engine for about 5
minutes and recheck the tension.
