◆ NOTE:
Tightening torque 10 Nm (90 in.lb). The allen screws
(12) and (13) are secured with LOCTITE 221.
Fit the governor (14) and the new gasket (15). Take care that the gear-
tooth system engages.
Depending on governor type different screws and nuts are needed. See

Fit the pressure oil line (18) to the governor flange and the oil pump
housing and secure with a clamp. The screw plugs (19) and (20)
normally remain closed. A pressure gauge for governor pressure
inspection can be connected at position (19) if necessary. The maxi-
mum governor pressure is between 21.5 bar (312 p.s.i) and 24.5 bar
(355 p.s.i), depending on governor type. The governor starts regulating
at 3400 to 4150 rpm.
Malfunction of the propeller governing may be caused by the following:
— incorrect adjustment of governor actuation
— malfunction of propeller governor
— insufficient oil pressure, oil pressure fluctuations
— propeller pitch control.
