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.
NOTE: The engine or pump will be mounted in the slotted holes on
the deck, determine this before continuing.
2. Scribe a mark at the base of the pump or engine (whichever
is mounted in the slotted holes) on the deck to be used as a
reference.
3. Loosen four pump or engine (whichever is mounted in the slot-
ted holes) mounting nuts .
4. FOR K PUMP UNITS ONLY
Loosen but do not remove pump stiffener bracket bolt.
5. Remove the belt.
6. Scribe a mark approximately 1/8" (3.2 mm) from the original
mark.
7. Slide the pump or engine to the new mark and retighten the
pump or engine mounting 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 or engine 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 or engine mounting
nuts (pump torque to 6–8 ft.- lbs./8.1–10.8 Nm, engine torque
to 8– 10 ft.-lbs. (10.8–13.6 Nm), stiffener bracket bolt (Torque to
10–12 ft.- lbs./13.5–16.3 Nm), and replace belt cover.
11. Reconnect spark plug wire.
Pulley and Fly wheel 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.
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 A2 in Figure.
The difference between mea sure ments 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 A2 mea sure-
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).
