Disassembly

1.

Follow the 

Pressure Relief Procedure

page 10.

2.

Disconnect the hoses from the lower and plug the 
ends to prevent fluid contamination.

3.

Models with Sealed 4-Ball Lowers:

 Remove the 

2-piece shield (9) by inserting a screwdriver straight 
into the slot, and using it as a lever to release the 
tab. Repeat for all tabs. 

Do not

 use the screwdriver 

to pry the shields apart. See F

IG

. 3.

4.

Loosen the coupling nut (10) and remove the collars 
(11). Remove the coupling nut (10) from the piston 
rod (R). Unscrew the lock nuts (5) from the tie rods 
(4). Separate the motor (1) and lower (2). 

5.

To repair the air motor or lower, see the separate 
manuals listed under 

Related Manuals

 on page 2.

Reassembly

1.

If the coupling adapter (8) and tie rods (4) have not 
been disassembled from the adapter plate (3), skip 
to step 2.

If the coupling adapter (8) and tie rods (4) have 
been disassembled from the adapter plate (3), fol-
low these steps:

a.

Screw the tie rods (4) into the adapter plate (3) 

and torque to 50-55 ft-lb (68-75 N•m). See F

IG

5. 

b.

Fill the cavity in the bottom of the motor shaft 

with grease. Lubricate the threads of the cou-

pling adapter (8). Screw the adapter (8) into the 

motor shaft until the pin holes align and install 

the pin (6).

c.

Continue to step 2.

2.

Assemble the coupling nut (10) over the piston rod 
(R).

3.

Orient the lower (2) to the motor (1). Position the 
lower (2) on the tie rods (4). 

4.

If you are reusing lock nuts (5) and the nylon of the 
lock nut is worn or cut, add blue thread locker to the 
tie rod threads.

This equipment stays pressurized until pressure is 
manually relieved. To help prevent serious injury from 
splashing fluid and moving parts, follow the Pressure 
Relief Procedure when you stop spraying and before 
cleaning, checking, or servicing the equipment.
