8. Replace belt guard.
9. Reconnect spark plug wire.
Adjusting Belt tension
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. Follow procedures 1-6 in Checking belt tension under
Maintenance.
. Scribe a mark at the base of the pump on the deck to be used
as a reference.
3. Loosen four pump mounting nuts.
4. Loosen but do not remove pump stiffener bracket bolt.
5. Remove the belt.
6. Scribe a mark approximately 1/8" (3. mm) from the original
mark.
7. Slide the pump to the new mark and retighten the pump mount-
ing nuts.
WARNING: Risk of moving parts. Use caution when rolling
belt onto flywheel, fingers can get caught between the belt and
flywheel.
8. With the pump secure, roll the belt over the flywheel and the
pulley.
9. Check the belt tension again. See Step 7 in Checking belt
tension under Maintenance.
10. When tension is correct, torque four pump mounting nuts (Torque
to 6–8 ft.- lbs./8.1–10.8 Nm), stiffener bracket bolt (Torque to
10–1 ft.- lbs./13.5–16.3 Nm), and replace belt cover.
11. 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.
. Allow the unit to cool.
3. Disconnect spark plug wire.
4. Drain air tank.
5. Remove outer belt cover.
6. Place a straightedge
(Q) against the outside
of the flywheel (R) and
the engine drive pulley
(S).
7. Measure the distance
between the edge of
the belt (T) and the straightedge at points A1 and A in Figure.
The difference between measurements should be no more than
1/16" (1.6 mm).
8. If the difference is greater than 1/16" (1.6 mm), loosen the
setscrew holding the engine drive pulley to the shaft and adjust
the pulley's position on the shaft until the A1 and A measure-
ments are within 1/16" (1.6 mm) of each other.
9. Tighten the engine drive pulley setscrew. Torque to 145–165 in.-
lbs. (16.4– 18.6 Nm).
10. Visually inspect the engine drive pulley to verify that it is
perpendicular to the drive motor shaft. Points B1 and B of Figure
should appear to be equal. If they are not, loosen the setscrew of
the engine drive pulley and equalize B1 and B, using care not to
disturb the belt alignment performed in Step 8.
