QS-5003 Installation onto Drum Mounted
Agitator (Refer to Figure 2)
1. adapter (47) has two thread sizes:
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
attach 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) se-
curely 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 loosening
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 as-
sembly 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 support-
ing 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 setscrews (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
contaminants could distort new oil
seal during installation.
5. Inspect gear and shaft assembly
(86) for wear grooves, burrs, or con-
tamination 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
installing. 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 setscrews (91) to
60 inch-pounds (6.8 n-m), minimum.
Refill gear box per gear box lubrica-
tion instructions.
approx. 1/8" Gap

bottom of fill line)
