Pressurize the TorqmotorTM with 100 p.s.i. (6.9 BAR) dry nitrogen and submerge in solvent to check for external
Check TorqmotorTM for rotation. Torque required to rotate coupling shaft should not be more than 50 ft. lbs . (68 N m)
Pressure port with "A" cast under it on housing 1181 is for counter-clockwise coupling shaft rotation as viewed from
the output end of coupling shaft. Pressure port with "B" cast under it is for clockwise coupling shaft rotation.
Use test stand if available, to check operation of the TorqmotorTM.
Keep the hydraulic system filled with one of the following:
10W40 SE or SF manufacturers suggested oil.
Hydraulic fluid as recommended by equipment manufacturer, but the viscosity should not drop below 50 SSU or
contain less than .125% zinc anti-wear additives.
Do not mix oil types. Any mixture, or an unproved oil, could deteriorate the seals. Maintain the
proper fluid level in the reservoir. When changing fluid, completely drain old oil from the system.
It is suggested also that you flush the system with clean oil.
Recommended filtration 20-50 micron.
Maximum operating temperature 200°F (93.3°C).
