[4] CHECKING/ADJUSTING AIR-COMPRESSOR BELT TENSION
[TENSION CHECK]
1. Open the machinery cover (1).
2. Press down on the middle of the belt (A) between the
crank pulley (2) and the compressor pulley (3) with
your thumb (approximately 17.7 N [1.8 kgf]) and
confirm that the deflection is the standard value of 4
mm.
[TENSION ADJUSTMENT]
1. Loosen bolts (4), (7), and (8).
NOTES
Only loosen bolts (4), (7), and (8); do not remove.
Removing them will make it impossible to position the
adjustment bracket (6).
2. Tighten or loosen bolt (5) and press down on the middle
of the belt (A) between the crank pulley (2) and the
compressor pulley (3) with your thumb (approximately
17.7 N [1.8 kgf]). Adjust the adjustment bracket (6)
position to ensure that the deflection (A) is 4 mm.
NOTES
Tightening bolt (5) increases the belt tension. Loosening
the bolt decreases the belt tension.
3. Tighten bolts (4) and (7) to secure the adjustment
bracket (6).
Tightening torque:
27 N∙m [2.8 kgf∙m]
4. Tighten bolt (8) to secure the compressor.
Tightening torque: 53 N∙m [5.4 kgf∙m]
CAUTION
When checking the tension of air-compressor belt, check the following at the same
time:
•
Check pulley, V groove and belt for damage and wear. In particular, make sure that the
belt is not in contact with the bottom of V groove.
•
If the belt has been stretched to leave no allowance for adjustment or it has scratches
and cracks and gives off a slipping/squeaking sound, replace the belt.
•
After replacing the V belt, conduct the adjustment again after running the Machine for
an hour.
