GENERAL DESCRIPTION
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.
WARNING
UAL INCLUDED FOR ADDITIONAL OPERATING AND
SAFETY PRECAUTIONS AND OTHER IMPORTANT INFORMATION.
WARNING
equipment failure resulting in severe injury or property damage. Do not exceed the maximum material
pressure of any component in the system.
WARNING

component rupture.
WARNING
cause re. The unit is rated for operation up to 130° F
(54° C). Be sure return lines are sized larger than supply lines and similarly pressure rated.
WARNING
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 compatible 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,

INSTALLATION
Use only flexible tubing for inlet and outlet porting to hydraulic source to prevent wear of components.
Be sure return lines are sized larger than supply lines and
similarly pressure rated.
Inspect the system hoses frequently for wear or damage and,
if necessary, replace them immediately. Never plug hose
leaks with your nger, tape or any similar devices.
Do not use PTFE tape on the inlet and outlet port
y
fittings. Loctite® 571 pipe thread sealant or equivalent is the recommended sealant.
Tighten the inlet and outlet fittings to 50 - 70 ft lbs
y
(67.8 - 94.9 Nm).
SERVICE
NOTE: The 67314-B hydraulic motor will contain about one
pint of hydraulic uid. Drain this uid before attempting any
disassembly.
NOTE: Do not disassemble this motor except in a clean area.
Any dust or dirt contamination of this assembly will shorten
the service life of this motor and other system components.
NOTE: All power supply pumps should have a ten micron
lter on the return line and a 100 mesh lter on the inlet. Failure to maintain lters will shorten service life of this motor
and other system components.
TROUBLE SHOOTING
If the pump will not cycle or will not deliver material.
Be certain to check for non-pump problems, including
y
kinked, restrictive or plugged inlet / outlet hose or dispensing device. Depressurize the pump system and clean
out any obstructions in the inlet / outlet material lines.
Check all seals, including track gaskets.
y
Check direction of “U” cup lips.
y
Motor is running beyond recommended temperature operating conditions.
Hydraulic oil cooling system is not working.
y
Piston seals are worn, replace seals.
y
Leakage from weep hole in retainer.
Detection of rod seal wear, when the amount this ex-
y
ceeds is 5 cc / day, replace wiper and rod seal.
Preventive maintenance issue, consult the factory for rec-
y
ommendations.
Motor stalls at fully retracted or extended position.
Insufficient pressure to motor (65 p.s.i. / 4.5 bar mini-
y
mum).
Springs need to be replaced.
y
Valve is damaged, service hydraulic motor.

DISASSEMBLY
REASSEMBLY
All threads are right hand. Refer to gure 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) “O” ring.
2.
Remove (8) trip plug and remove (5) ball, (38) spring follower, (6) spring and (7) “O” ring.
3.
Move piston rod to the fully retracted position and pull
(4a) spool out of (4b) sleeve through the top.
.
4
Using the ats on (18) trip rod to hold, remove and discard (3a) nut. DO NOT RE-USE. The trip rod wrench ats
are only accessible through the port holes that retain the
(8) trip plug. This will require a narrow width open-end
wrench.
NOTE: Be very careful when removing the spool from
the valve. The nish 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) “O” rings and (33) back-up rings.
10. Remove (22) piston rod assembly and (23) cylinder from
(9) cylinder head and remove (10) “O” ring.

(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 separately.)
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.
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 ats on the (14) piston screw and unthread.
17. Remove (21) “O” ring from (22) piston rod.
18. Remove the (18, 19, 20, 45) trip rod assembly.
19. Using the ats on the (18) rod, remove and discard the
two (3b) nuts. DO NOT RE-USE.
Thoroughly clean and lubricate all seals. Replace all soft
parts with new ones included in the repair kit.

piston on it.
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 anges are facing each other. NOTE: (3b) nut to be
hand tight. While holding (18) trip rod on ats, assemble
(3b) nut to (18) trip rod and tighten to 90 - 110 in. lbs
(10.2 - 12.4 Nm).
6.

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 alternately and apply 44 - 56 ft lbs (59.7 - 75.9 Nm). NOTE:
