Changing V-belt

To change the V-belt drive on your air compressor:

1.Remove the belt guard from the air compressor shown in Figure 11. The guard is attached to the compressor frame by the two mounting bolts shown in Figure 11.

Figure 11. Belt Guard and

mounting bolts.

2.Loosen the four nuts (one side shown in Figure 12) that secure the motor to the compressor frame so the motor can slide towards crankcase, relieving the tension on the V-belt.

Figure 12. Mounting bolt locations.

3.Remove the V-belt from the motor pul- ley and fly pulley.

4.Install the new V-belt.

5.Reposition the motor in its original place so the belt is tensioned, and secure the four mounting bolts loos- ened in step 2.

6.A properly tensioned V-belt will have about a 1Ú2 inch deflection as shown in

Figure 13. Replace the belt guard.

7.Replace belt gaurd.

Make sure the V-belt is properly ten- sioned. If the V-belt is too tight, the motor could overheat and cause machine damage or fire. If the V-belt is too loose, the belt will slip on the pulley and cause belt damage and compressor inefficiency.
