Checking Belt Tension (Fig. 1)

WARNING: Hot surfaces. Risk of burn. Aftercooler, pump head, and surrounding parts are very hot, do not touch (see the Hot Surfaces identified in Fig. 2). Allow compressor to cool prior to servicing.

1.Ensure engine ON/OFF switch (C) is in the OFF Position.

2.Allow the unit to cool.

3.Disconnect spark plug wire.

4.Drain air tank.

5.Remove eight belt guard screws.

6.Remove outer belt cover.

7.Measure belt tension. Proper tension is achieved when a three

(3) pound weight or equivalent finger pressure applied midway between the motor pulley and compressor flywheel causes a 1/4" (6.35 mm) deflection of the belt., if adjustment is needed see Adjusting Belt Tension under Maintenance.

8.Replace belt guard.

9.Reconnect spark plug wire.

Pulley and Flywheel

Alignment

The air compressor flywheel and engine pulley must be in-line (in the same plane) within 1/16" (1.6 mm) to ensure belt retention within flywheel belt grooves. To check alignment:

1.Ensure engine ON/OFF switch (C) is in the OFF Position.

2.Allow the unit to cool.

3.Disconnect spark plug wire.

4.Drain air tank.

5.Remove outer belt cover.
