Pressure port with "A" cast under it on housing (15) is for clockwise coupling
shaft rotation as viewed from the output end of coupling shaft. Pressure port
with "B" cast under it is for counter clockwise coupling shaft rotation.
CAUTION: If the MAF TorqmotorTM is reassembled with rotor and coupling shaft
internal splines one tooth (45°) or three teeth (135°) out of phase in either
direction, the MAF will not function.
If the MAF TorqmotorTM is reassembled with rotor and coupling shaft internal
splines two teeth (90°) out of phase, in either direction, it is fully functional but,
the direction of rotation of coupling shaft will be reversed to what is designated
for a pressurized port "A" or port "B".
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-
CAUTION: DO NOT MIX OIL TYPES. ANY MIXTURE, OR AN
UNAPPROVED 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 2000F (93.3°C).
