1 2 3 4 5 6
P - A B C - X / Y
P - 9 1 0 - 010 / A
  1. P = Propeller Governor
  2. A = Internal Jihostroj´s marking, reserved digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
  3. B = Basic design arrangement:
    1 = I, CW = pressure to increase pitch, CW rotation facing governor base, CCW rotation facing engine pad
    2 = I, CCW = pressure to increase pitch, CCW rotation facing governor base, CW rotation facing engine pad
    3 = D, CW = pressure to decrease pitch, CW rotation facing governor base, CCW rotation facing engine pad
    4 = D, CCW = pressure to decrease pitch, CCW rotation facing governor base, CW rotation facing engine pad
  4. C = Special design arrangement:
    0 = Standard
    1 = Feathering
    3 = Electronic control
    4 = Connection to accumulator
  5. X = Application number defining settings of governor – relief valve pressure, max. RPM, control arm travel and position etc.
  6. Y = Control head model:
    A = Axial, adjustable type head - short
    B = Axial, adjustable type head - long
    AL = Axial, adjustable type head - short , reverse arrangement

NOTE:

For JIHOSTROJ unknown reason, MT PROPELLER has started to designate it´s propeller governors in a similar way as JSV did before already. They are using similar coding as P-850-X, P-860-X, P-870-X, P-880-X, P-9()()-(), etc.

Please note that MT governors have different design and are manufactured by MT!

Please consult the governor nameplate for governor origin!
