INSTALLATION
Use only flexible tubing for inlet and outlet porting to hy-
draulic 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
fittings. Loctite® 571 pipe thread sealant or equiva-
lent is the recommended sealant.
Tighten the inlet and outlet fittings to 50 - 70 ft lbs
(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. Fail-
ure 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

pensing device. Depressurize the pump system and clean
out any obstructions in the inlet / outlet material lines.
Check all seals, including track gaskets.
Check direction of “U” cup lips.
Motor is running beyond recommended temperature op-
erating conditions.
Hydraulic oil cooling system is not working.
Piston seals are worn, replace seals.
Leakage from weep hole in retainer.
Detection of rod seal wear, when the amount this ex-
ceeds is 5 cc / day, replace wiper and rod seal.
Preventive maintenance issue, consult the factory for rec-
ommendations.
Motor stalls at fully retracted or extended position.
Insufficient pressure to motor (65 p.s.i. / 4.5 bar mini-
mum).
Springs need to be replaced.
