GENERAL DESCRIPTION  
vent over-pressurization of the system and possible  
component rupture.  
WARNING  
The 4.125 square inch hydraulic motor is a general purpose  
power unit and is used on many ARO industrial 2-ball, 4-ball  
and chop-check pumps. It utilizes tie rod type construction  
for serviceability and connects to the various lower pump  
ends by tie rods.  
Due to frictional losses in the system, a greater horsepower  
is required to run the motor. Power supplies generating less  
than shown as required in the Performance Specifications  
above will work with the motor but at a reduced pressure or  
cycle rate.  
Excessive hydraulic oil temperature can  
cause fire. The unit is rated for operation up to 130° F  
(54° C). Be sure return lines are sized larger than sup-  
ply lines and similarly pressure rated.  
WARNING  
Never service or disassemble the unit or  
unit components without relieving hydraulic system  
pressure ꢀrst. The high pressures involved could  
cause serious injury.  
NOTE: If this pump was purchased separately (not part  
of a system), consult your sales representative for com-  
patible dispensing accessories which will best match the  
application. All accessories must be able to withstand the  
maximum pressure developed by the pump.  
A replacement warning label is available upon request,  
pn \ 94576.

DISASSEMBLY  
REASSEMBLY  
All threads are right hand. Refer to figure 2, page 3. These  
procedures are for the installation of repair kit parts.  
Disconnect power supply and relieve all system pressure  
prior to servicing. Carefully remove the parts, inspect parts  
for damage, nicks or excessive wear and determine if any  
parts will need replacement.  
1. Remove (1) top plug and remove (2) “Oring.  
2. Remove (8) trip plug and remove (5) ball, (38) spring fol-  
lower, (6) spring and (7) “Oring.  
Thoroughly clean and lubricate all seals. Replace all soft  
parts with new ones included in the repair kit.  
1. Install (28) rod seal and (10) “Oring into (26) motor base.  
2. Install (30) wiper into (31) seal retainer and slip in (29)  
bushing.  
3. Slide (25, 22) piston rod assembly into (26) motor base  
and retainer assembly from step #2 above.  
4. Insert (21) “O” ring onto (22) piston rod and place (15)  
piston on it.  
3. Move piston rod to the fully retracted position and pull  
(4a) spool out of (4b) sleeve through the top.  
4. Using the flats on (18) trip rod to hold, remove and dis-  
card (3a) nut. DO NOT RE-USE. The trip rod wrench flats  
are only accessible through the port holes that retain the  
(8) trip plug. This will require a narrow width open-end  
wrench.  
5. Assemble (45) retaining ring, (19) trip washer, (20) trip  
spring and (19) trip washer to (18) trip rod, securing with  
one (3b) nut. NOTE: Orient the two (3b) nuts such that  
the flanges are facing each other. NOTE: (3b) nut to be  
hand tight. While holding (18) trip rod on flats, assemble  
(3b) nut to (18) trip rod and tighten to 90 - 110 in. lbs  
(10.2 - 12.4 Nm).  
6. Place (18, 19, 20, 45, 3b) shifter assembly into (22) piston  
rod and thread (14) piston screw into (22) piston rod.  
7. Torque (14) piston screw to 100 - 120 ft lbs (135.6 - 162.7  
Nm) with (25) piston rod adapter in a heavy vise.  
8. Put (17) seal and (16) wear ring on (15) piston.  
9. Push (22) piston rod to fully extended position and place  
(23) cylinder over the piston assembly.  
NOTE: Be very careful when removing the spool from  
the valve. The finish of this part is critical for proper  
motor performance. Any nicks, scratches or dirt may  
damage the set.  
5. Remove (43) cap screws.  
6. Slide (31) seal retainer, (29) bushing and (30) wiper off  
(22) piston rod and (25) piston rod adapter.  
7. Remove (37) tie rod nus and (35) washers.  
8. Clamp (9) cylinder head and remove (26) motor base by  
tapping with a soft hammer, then remove (10) “O” ring  
and (28) polypack rod seal.  
9. Remove (34) hydraulic tube from (9) cylinder head and  
remove (32) “Orings and (33) back-up rings.  
10. Remove (22) piston rod assembly and (23) cylinder from  
(9) cylinder head and remove (10) “Oring.  
10. Seat the (23) cylinder onto the motor base. NOTE: Petro-  
leum jelly is recommended for ease of assembly on allO”  
rings and inside the cylinder.  
11. Replace the three (13) “Orings on (4b) valve sleeve.  
12. Push (4b) valve sleeve / spool set straight into (9) cylin-  
der head.  
13. Place (11) sleeve washer behind (4b) valve sleeve and  
retain this with (12) retaining ring.  
11. Separate (22, 17, 21, 16, 15, 14) piston rod assembly from  
(23) cylinder.  
12. Remove (17) seal and (16) wear ring from (15) piston.  
13. If further disassembly is required, such as removal of (22)  
piston rod, (4) valve spool assembly, or (45, 20, 19, 18)  
shifter assembly, see next section. (Order “O” rings sepa-  
rately.)  
14. Put two (33) back-up rings and two (32) “O” rings onto  
(34) hydraulic tube with back-up rings on the hydraulic  
tube first.  
15. Push tube assembly (34, 33, 32) into (26) motor base.  
16. Place (10) “O” ring on (9) cylinder head, lower (9) cylinder  
head onto the (23) cylinder and (34) hydraulic tube with  
the (18) trip rod through the center of the valve.  
17. Feed (36) bolts through (26) motor base and apply (35)  
washers and (37) nuts to the bolts. Tighten fasteners al-  
ternately and apply 44 - 56 ft lbs (59.7 - 75.9 Nm). NOTE:  
Must alternately rundown fasteners to prevent cutting  
the (10) “Orings.  
Removal of (4) sleeve and spool assembly.  
14. Remove (12) retaining ring and (11) sleeve washer from  
(9) cylinder head. Push the (4b) sleeve carefully down  
through the (9) cylinder head using a soft faced tool.  
NOTE: The finish of the upper face of the sleeve is  
critical for intended operation. Any nicks or scratches  
may damage the entire (4) set.  
18. Assemble (31) seal retainer, retaining with six (43) cap  
screws.  
19. Move piston to the retracted position.  
Removal of (22) piston rod.  
15. Place the (22, 21, 17, 16, 15, 14) piston rod assembly in  
a vertical position with the (25) piston rod adapter in a  
heavy vise.  
NOTE: Never clamp on the (22) piston rod.  
16. Grip the flats on the (14) piston screw and unthread.  
17. Remove (21) “Oring from (22) piston rod.  
18. Remove the (18, 19, 20, 45) trip rod assembly.  
19. Using the flats on the (18) rod, remove and discard the  
two (3b) nuts. DO NOT RE-USE.  
20. Pull (18) trip rod through the head and place the (4a)  
spool on the trip rod. Using the (3a) nut and the trip rod  
flats, tighten the (3a) nut to 90 - 110 in. lbs (10.2 - 12.4  
Nm).  
21. Carefully push the spool / trip rod into the sleeve, creat-  
ing the (4) valve.  
22. Place (2) “O” ring on (1) top plug and tighten in (9) cylin-  
der head.  
23. Place (7) “O” ring on (8) trip plug. Place (5) ball in (9) cyl-  
inder head and (6) spring and (38) spring follower in (8)  
trip plug.  
24. Thread the (8) trip plug into the (9) cylinder head.
