The tank has been filled up with a clean fluid in proper conditions.
We recommend to flush the system with an external pump prior to the
start-up.
It is important to bleed the air off the circuit and the motor itself.
Manually, fill the motor housing with fluid, and connect the motor to the
circuit.
Start rotation in a jogging manner until a prime is picked up, and in-
crease the speed from 500 to 1000 rpm.
Check that there is no leakage or air suction neither at the ports (inlet,
outlet, drain), nor at the shaft end.
If the motor does not prime properly in the first minute, or pressure can
not be obtained, it should be shut down and condition corrected.
The motor should be started at low pressure and low speed until the
fluid warms up, before running it at high pressure or speed.
The first valve on the circuit should be open to tank.
We recommend the use of air bleed off valves.
Warning : this has to be done in low pressure mode as it could create
a dangerous fluid leak. Make sure that the pressure cannot rise (open
center valve to tank, pressure relief valve unloaded ...).
When oil free of air appears, tighten the connectors to the correct tor-
que.
The motor should prime within a few seconds. If not, please consult the
troubleshooting guide (pages 32 & 33).
If the motor is noisy, please troubleshoot the system.
• The mating female spline should be free to float and find its own cen-
ter. If both members are rigidly supported, they must be aligned within
0,15 TIR (0.006" TIR) or less to reduce fretting. The angular alignment
of two splines axes must be less than ± 0,05 per 25,4 radius (± 0.002"
per 1" radius).
• The coupling spline must be lubricated with a lithium molydisulfide
grease, disulfide of molybdenum or a similar lubricant.
• The coupling must be hardened to a hardness between 29 and 45
HRC.
• The female spline must be made to conform to the Class 1 fit as des-
cribed in SAE-J498b (1971). This is described as a Flat Root Side Fit.
Parker supplies the M5AS* series keyed shaft motors with high strength
heat-treated keys. Therefore, when installing or replacing these motors,
the heat-treated keys must be used in order to ensure maximum life
in the application. If the key is replaced, it must be a heat-treated key
between 27 and 34 R.C. hardness. The corners of the keys must be
chamfered by 0,76 mm to 1,02 mm (0.03 to 0.04) at 45° to clear the
radii in the key way.
The alignment of keyed shafts must be within tolerances given for spli-
ned shafts here above.
The torque for a steel coupling and a nut, of at least grade 8.8 quality
is 80 Nm (59 ft.lbs)
It is compulsory to install a castle nut + cotter pin when right hand ro-
tation and bi-rotational.
The max. permissible load values are given in the sales catalogue.
