The basic pumpconsists oftwo major components: 1. AirMotor, 2. Low­er Pump. The motorisconnected to thelower pumpendby a spacersec­tion. Thisallows for lubrication of the upper packing glandand prevents
motor contamination because of normal wear and eventual leakage
through the material packing gland. The air motor isremovable andis to
be serviced separately. Refer to air motor manual for service and parts.

It is recommendedthat anoiler be installedin theairline as closeas pos­sible to thepump. This increasestheservice lifeofthe pump byreducing
wear of the air motor’s internal parts.

• Periodically flush entire pump systemwith a solvent that is compat-

ible with the material being pumped.

• Pump disassembly should be done on a clean work bench with

clean cloths to keep parts clean.

• If replacement parts are necessary, consult drawing containing

parts for identification, include the part name and number when or­dering.

• Before assembling, lubricate parts where required. When assem-

bling ‘‘O” ringsorparts adjacent to‘‘O” rings, caremust be exercised
to prevent damage to ‘‘O” rings and ‘‘O” ring groove surfaces.

• If pump isto be inoperativefor anunspecified period oftime, discon-

nect air and relieve all pressure.

PUMP DISASSEMBLY

NOTE: All threads are right hand.

1. Clamp pump assembly in a vise on the air motor base assembly.

2. Unscrew 90571 Lock Nut. (See Figure 2)

3. Place a strap wrench around 92483 tube and loosen by turning
counterclockwise. If the wrench slips on the tube, wrap a piece of
400 grit sand paper around tube and under strap wrench.
Note: Pipe wrench will damage the finish of the tube.

4. After the tube hasbeenpulled down toexposethe air motorrod, hold
air motor piston rod and remove the Y145--2 retaining ring and
90746 pin from the air motor piston rod.

5. Remove the air motor assembly from the vise.

6. Vise the lower pump and push (6) piston rod untilflats on(16) rodar
exposed at other end of pump.

7. Unscrew (20) stop nut and remove (19) washer and (18) washer
from (16) rod.

8. Unscrew (17) primer tube from (7) tube and sleeve and remove (9)
washer,(10) retainingring, (11) ‘‘U” cup, (12)body,(13) sleeve,(14)
gasket and (15) valve seat.

9. Hold (6) piston rod and unscrew (16) rod from assembly.

10. Push (6) rod until (8) connector is exposed on other end of (7)tube.

11. Unscrew and remove (8) connector from (6) rod.
