Just to be sure, Blake and I queried Jason at Aircraft Propeller. He offered these tidbits:
INSTALLATION INSTRUCTION
Prepare new mounting gasket. Coat the gasket with a suitable release agent before installation.
a) Check that mounting studs project a minimum of 1.250? (31.75 mm) from face of engine pad.
b) Clean engine pad, studs and mounting hardware before installing the new mounting gasket.
c) Torque the 5/16-18 (Lycoming) mounting nuts to 110-150 in lbs (12-17 Nm) and the 5/16-24 (Continental) nuts to 180-220 in lbs. (21-25 Nm).
d) Reattach the propeller control using new mounting hardware and adjust the linkage per aircraft service information.
CONTROL LEVER POSITION FIELD ADJUSTMENT
-Control Lever Angle. Default is 290 deg. Can I easily change the lever angle around after I figure out what works best?
Yes! Here are the instructions on how to do so:
Control lever position field adjustment
Use this procedure to accommodate unique prop control positions
a) Remove the cover flange retaining screw safety wire.
b) Loosen the six screws cover flange screws and gently turn the
control head to an appropriate position.
c) After establishing the desired control position, tighten and torque
the six screws to 16?1 in. lbs. (1.6-1.8 Nm.)
d) Re-safety the cover flange retention screws with new safety wire.
e) After run-up, check for oil leaks, none are permitted.
HIGH PROPELLER RPM FIELD ADJUSTMENT
a) Remove the safety wire from the high RPM stop screw and rotate
the control lever to the high RPM stop.
b) Loosen the high RPM jam nut and set high propeller RPM by
turning the stop screw. One full turn clockwise will reduce RPM by
approximately 25. One full turn counter-clockwise will increase
RPM by approximately 25. Tighten and re-torque jam nut
between 24.8 and 28.3 in. lbs (2.8-3.2 Nm)
Adjustment instructions apply to both CW and CCW levers.
Typical head and control lever assembly is shown.
Note: Adjust high RPM only. Do not adjust the low RPM stop. Minimum RPM is achieved prior to low stop contact.
-Control Lever Rotation. Do I need Clockwise or Counter-Clockwise?
Depends on where your control cable attaches to the lever. The lever rests against the high RPM/low pitch stop, therefore when trying to determine this, imagine how the lever would rotate as your pull the prop control toward a lower RPM. Whatever the answer is (clockwise or counter-clockwise) is what you would put on the form.
-Pressure to Increase P-520, Yes for Non-Counterweighted prop. What does this mean?
A non-counterweighted prop is a standard, non-aerobatic, non-feathering propeller that uses oil pressure to INCREASE the blade pitch angle.
-Pressure to Increase P-540, Yes for Counterweighted prop. What does this mean?
A counterweighted prop is one that uses oil pressure to DECREASE the blade pitch angle. This is typically found on feathering propellers or aerobatic propellers. Unless you have either of these, you probably don?t need this type of governor.
Either Blake or I can get one of these top notch governors for your aircraft.
