8.2.7 INSPECTION AND ADJUSTMENT OF AIR CONDITIONING COMPRESSOR
BELT
Be sure to stop the engine before inspection and maintenance. Inspecting and maintaining the running
engine may cause injury by being caught in the cooling fan or fan belts.
Replace the belt with a new one if flaking or breakage is found on the belt by the inspection. Keep
the belt away from oil. The service life may be shortened if it slips on oil.
1. Move the pilot control shut-off lever to the
"LOCKED" position, and then stop the
engine.
2. Use the starter key to open the bonnet and
hold it with the stay.
3. If the belt deflection is 5.4 mm when applying
a force of 16 N•m to the center between
pulleys, it is normal.
4. Loosen double nut (1) of the idle pulley
slightly and turn adjusting bolt (2) to adjust
the belt tension.
5. Tighten double nut (1).
Tightening torque:23
±
2.3 N•m
6. After adjustment, run the engine at low idling
for about 5 minutes before checking the belt
tension again.
