When assembled vertically, always be careful to prevent any air from
being trapped in the motor housing.
Please contact Parker.
All fluid lines, either pipe, tubing or hose, must be of adequate size and
strength to assure free flow to and from the motor. An undersized inlet
line will restrict the fluid flow to the motor and prevent proper operation
by creating turbulences and aeration.
If rigid pipe or tubing is used, the workmanship must be accurate in
order to eliminate strain on the motor housing or the fluid connectors.
Sharp bends in lines should be eliminated whenever possible.
All the system piping must be cleaned with solvent or an equivalent
cleaning agent before being connected to the motor.
Do not use galvanized pipe. Galvanized coating may flake off after
continued use.
To be mounted in accordance with SAE J1926/2, ISO 6149/2 and ISO
1179.
These externally drained motors must have a drain line connected to
the center housing drain connection of sufficient size to prevent back
pressure in excess of 3.5 bar (50 PSI), returning directly to the reser-
voir below the surface of the oil, and as far away as possible from the
suction pipe of the pump.
It is preferable to install the center housing with the drain hole upward
to facilitate the purge of the motor.
If the motor is mounted shaft up, the drain line must have a bend above
the motor to purge it and to be sure that the shaft seal is lubricated
(see drawing).
Le circuit hydraulique doit être conçu de façon à ce que lorsque l'on
coupe le moteur, celui-ci reste alimenté en huile, sans risque de cavi-
tation. (prévoir une valve anti-cavitation si necessaire).
Les moteurs M5AS* uni-directionnels sont équipés d'une valve anti-
cavitation interne.
