Chapter 8 PERIODIC INSPECTION AND MAINTENANCE PROCEDURES
Basic engine
Belt and belt tension - Inspect and Adjust
If defects such as cuts or surface separations are found during inspection, replace the belt.
Keep oil and grease away from the belt. They may cause the belt to slip and shorten the service life.
Excessive belt tension can cause rapid wear of the alternator bearing and shorten the service life of the belt.
Adjust the belt tension accurately by following the procedures below.
Belt - Inspect
1. Inspect the belt visually for separation or damage. If any abnormality is found, replace the belt with a new one.
2. Inspect belt tension (deflection).
Push the belt downward at the midway between pulleys. If the deflection is 12 mm [0.47 in.], the tension is correct.
Belt pushing force: Approx. 98 N {10 kgf} [22 lbf]
If the deflection of belt is not within the standard, adjust the belt tension.
Belt tension (Alternator side) - Adjust
1. Remove the belt cover.
2. Loosen all retaining bolts of the alternator and ad-
justing plate.
3. Move the alternator to adjust the belt tension.
4. After adjusting the belt tension, tighten all retaining
bolts of the alternator and adjusting plate.
5. Install the belt cover.
