Flush the Air Motor

If the motor is sluggish or inefficient, flush it with 
non-flammable solvent in a well-ventilated area.

1. Follow the 

Pressure Relief Procedure

. See 

page 19.

2. Add several teaspoons of solvent, or spray the sol-

vent directly into the motor.

3. Rotate the shaft by hand in both directions for a few 

minutes.

4. Reconnect the air line and slowly apply pressure 

until there is no trace of solvent in the exhaust air.

5. Lubricate the motor with a squirt of lightweight oil in 

the chamber.

Pneumatic Agitator Assembly 
Service

Air Motor

1. To remove the air motor for service, use a 3/16 hex 

to remove the three setscrews (7) on the bung 
adapter (5).

2. Lower the adapter (5) on the shaft (2) so coupler (3) 

is accessible.

3. Use a 1/8 hex to remove the top two setscrews (4) 

on the coupler (3).

4. Lift the air motor (1) straight up off the coupler (3).

If the air motor (1) requires more than installation of 
a service kit, it is usually quickest and easiest to 
send it to the Graco distributor for repair or replace-
ment.

If the air motor blades need replacing or foreign 
material is present in the motor chamber, an experi-
enced mechanic may remove the end plate oppo-
site the drive shaft end. Do not pry with a 
screwdriver. It will dent the surface of the plate and 
body, causing leaks. Use a puller tool, which will 
remove the end plate while maintaining the position 
of the shaft.

Shaft and Agitator Blades

1. Remove the shaft (2) from the tank. Clean with a 

compatible solvent and inspect the shaft (2) and 
blades (13, 14) for wear or damage.

2. If parts need replacing, follow 

Air Motor

 procedure 

to remove the air motor.

3. Use the 1/8 hex to remove the other two 

setscrews (4) on the coupler.

4. Slide the shaft off (2).

5. If needed, use a 3 mm (1/8 in.) hex to remove the 

setscrew (4) on the hub assembly (13 or 14). Slide 
the hub/blade assembly off of the shaft.

6. To install a new hub/blade assembly, slide it onto 

the shaft. The setscrew must always remain on the 
top, with the blades hanging down, so the blades 
will pass into and out of the bung hole.

NOTE: Air Motor Repair Kits are available. Order 
repair kit 224954.

Reassembly

1. Slide the shaft (2) into the coupler (3). Use a 1/8 hex 

to tighten the setscrews (4). Torque to 80 in-lb 
(9 N•m).

2. Raise the bung adapter (5) on the shaft (2) to recon-

nect to the air motor. Use a 3/16 hex to tighten the 
three setscrews (7) on the bung adapter. Torque to 
80 in-lb (9 N•m).

NOTICE

Not lubricating the air motor will cause air motor fail-
ure.

NOTICE

Damage to the level sensors may occur when an 
agitator is removed. To avoid damage to level sen-
sors, remove the agitator assembly while keeping 
the agitator blades away from the level sensor 
assemblies.
