B: INSPECTION
1. TIMING BELT
1) Check timing belt teeth for breaks, cracks, and wear. If
any fault is found, replace belt.

Slight traces of oil at rod’s oil seal does not indicate a
problem.
2) While holding tensioner with both hands, push the rod
section against floor or wall ensuring the rod section will
react as follows:
(1) When applying a force of 147 N (15 kg, 33 lb), the
rod section should not sink.
(2) When applying a force of 147 to 490 N (15 to 50 kg,
