1-1/2" NPS (M) on one end and
2" NPS (M) on the other end. Choose the
proper thread size and place adapter
over agitator shaft of drum and screw
down securely.
2. Select proper driver shaft (46) and at-
tach it to drive coupling assembly (48)
with driver pin (45) and cotter pins (44).
Place this assembly on shaft of drum
agitator.
3. Slip air motor support (39) down over
drive coupling assembly (48) and
adapter (47).
4. Tighten air motor support (39) securely
with screw assembly (43).
5. Install gear box (38) on air motor sup-
port (39), being sure to engage shaft
of drive coupling assembly (48).
6. Tighten cap screw and hex nut (40
and 42).
7. Connect air supply line to air adjusting
valve (52).
OPERATION
Before operating air motor, lubricate as
covered in next section. Open valve to
main air line; then slowly open air adjust-
ing valve until agitator turns. To extend air
motor life, adjust air pressure setting to run
motor at about one revolution per second.
The agitator should be run continuously
while using the tank.
PREVENTIVE MAINTENANCE
Air Motor Lubrication
Failure to properly lubricate the air
motor will result in premature mo-
tor failure and will void warranty.
Lubricate air motor daily by adding 4
or 5 drops of SAE 10 weight oil into
air inlet fitting. For convenience, an
automatic oiler may be connected
to the air inlet.
Periodically - Remove air adjusting valve
and air strainer and flush motor with a
clean suitable solvent. Remove trapped
particles from screen in air inlet and clean
air strainer felt.
Air Motor Gear Box Lubrication
Every 2 Days - Remove oil fill plug and
check oil level. Proper oil level is indicated
on outside of gear box housing. If oil level
is low, add 140-weight SAE Gear Oil or a
high quality worm gear lubricant. Replace
pipe plug and tighten to 20 foot-pounds
(27 N-m) of torque.
Note
Gear box oil is most easily drained
just after motor operation, while oil
is still warm.
Note
Do not overfill. Overfilling may cause
oil to leak out of vent cap on top of
gear box.
After first 250 hours of operation, remove
gear box and drain gear oil. Refill gear box
with 140-Weight SAE Gear Oil or a high
quality worm gear lubricant. Replace pipe
plug and tighten to 20 foot-pounds (27
N-m) of torque.
6 Months or 2500 Operating Hours - Re-
place gear oil according to instructions
above. Replace gear oil more often if
environment causes oil to become con-
taminated during use.
REPLACEMENT OF PARTS
Removal of Air Motor and Gear Box
(Refer to Figure 3 - typical assembly.)
1. Follow pressure relief procedure
(Ref. Pg. 1) before removing or loosen-
ing any components.
2. Turn off valve to main air supply
and disconnect air adjusting valve (65)
at nipple (64).
3. Loosen upper cap screw (61) and
remove air motor and gear box
assembly from support (60).
Air Motor (Refer to Figure 4)
Holes must be drilled for new dowel pins
(72) after assembling front plate (77) on
new body (76) for alignment of parts.
Do not pry front plate (77) or end plate
(71) from air motor body (76) with a screw
driver; this will dent the surface of the
body and plates causing leaks. A puller
tool should be used to remove the plate
from the motor body while maintaining
the position of the shaft.
Always install new gaskets (73) when
reassembling air motor.
Assemble the end plates to the body
using an arbor press with a pusher acting
on both races of the bearing while rigidly
supporting the opposite (drive) end of
the shaft.
Gear Box (Refer fo Figure 5)
1. Remove oil fill plug (88) or cover plate
(84) and drain gear box lubricant.
2. Remove set screws (91) and remove
gear box from air motor.
3. Disassembly gear box per exploded
view, Figure 5. Discard gaskets (87 and
92). Do not remove oil seal (90) unless
leakage or seal damage is indicated.
4. If oil seal (90) was removed, inspect
seal seating bore in housing (89).
Remove any burrs or contaminants
from seal seating bore. Burrs or con-
taminants could distort new oil seal
during installation.
5. Inspect gear and shaft assembly (86) for
wear grooves, burrs, or contamination
of seal seating area. If seal seating area
is damaged, shaft must be repaired or
replaced.
6. Inspect all other parts for wear spots,
chipping, or other damage. Replace
damaged or worn parts.
7. If oil seal (90) is being replaced, inspect
new seal for damage before install-
ing. Use arbor press to install seal.
Press fixture diameter must be close
fit with gear box bore diameter to
avoid damage to seal. Install with inner
casing and sealing lip toward bottom
of bore. Drive seal squarely into bore
to avoid warping. Check that seal
is fully seated all around at bottom
of bore.
8. Reassemble gear box per exploded
view. Install new gaskets (87 and 92).
Just prior to assembling gear box with
air motor, apply a small dab of thread
locking compound (81) to threads of
setscrews (91). Connect motor and
gear box and torque set screws (91) to
60 inch-pounds (6.8 N-m), minimum.
Refill gear box per gear box lubrication
instructions.
