Trim system
Venting system
The relief valve assemblies
Reconnect main battery switch and operate the trim
pump (system is self-bleeding). Re-check the oil level
and add if necessary.
If the original factory fitted valves have to be re-
moved, this will alter the factory setting, and new
valves will have to be installed.
NOTE! Replacement valves are set from the factory
and must not be opened.
Test
Once the system has been vented, operate the trim
pump for proper operation. Check pump and hose con-
nections for leaks.
Adjusting the trim instrument
Duoprop
The replacement relief valves have a different design
than the original factory installed valves. See explod-
ed view, pos (A, B, C), on page 155. Use a 7/16"
wrench to remove and install valves.
Singleprop
WARNING! Place wrench on lower part of valve
to avoid altering the setting when tightening.
Installing the trim pump
Mount trim pump and bracket. Remove the protective
plugs from the pump and hoses. Connect the hoses to
their respective connections on the pump. (A, fig.
above) is the high pressure connection and (B, fig.
above) is the low pressure connection.
Connect the wiring harness, the ground (-) and posi-
tive (+) cables.
The trim instrument is always delivered together with
Duoprop drives. It is set to a trim limit of 6° and the
switch is sealed. Refer to the enlarged view for the
Duoprop drive where switch 4 in ON.
Fill the reservoir with recommended oil to the proper
level (between MIN and MAX marks).
NOTE! No other trim limit is permitted for the Duoprop
drive. The seal must not be broken.
However, if the instrument is mounted to a Singleprop
drive, the seal must be broken and the instrument re-
set to 12° trim limit. Refer to the enlarged view for the
Singleprop drive where switch 4 down and switch 2 is
ON.
