Drive Belt: Testing and Inspection

DRIVE BELTS


Checking






- Inspection should be done only when engine is cold or over 30 minutes after the engine is stopped.

1 : Generator
2 : Water pump
3 : Crankshaft pulley
4 : A/C compressor (with A/C models)
: Idler pulley (without A/C models)
5 : Idler pulley
6 : Drive belt

- Visually check belts for wear, damage, and cracks on inside and edges.
- Turn crankshaft pulley two time clockwise, and make sure tension on all pulleys is equal before doing the test.
- When measuring deflection, apply 98 N (10 kg, 22 lb) at the marked point.
- Measure the belt tension and frequency with acoustic tension gauge at the marked point.

CAUTION:
- When the tension and frequency are measured, the acoustic tension gauge should be used.
- When checking immediately after installation, first adjust it to the specified value. Then, after turning crankshaft two turns or more, re-adjust to the specified value to avoid variation in deflection between pulleys.
