Hi :
Vans no longer sells the Hartzell Narrow Deck Governor.
O-540 S-1-32 for Narrow Deck Engines . Does anyone know the Hartzel part number and where the best place to get one would be?
Thanks.
So If I understand correctly, the S-1-26 will fit the ND and has the right ration, but it is limited to 2575 rpm. There must be a way to raise the RPM to 2700. Anyone knows how to do this.

I am new to CS props, but is was my understanding they could drive a range of blade movement and it was an issue of clocking the arm and adjusting the stop screw to get the max RPM you want at the expense of the minimum RPM level. The different ratios should just change the size of the adjustment range (max vs min RPM adjusted).
I can't see them making a gov that couldn't turn 2700, though they might set the screw for 2575 at the factory.
Can someone more experienced school me on this?

This comes from the Jihostroj web site -
Maximum governor drive RPM is defined by propeller maximum RPM and gear ratio between the propeller shaft and governor drive. This value is then assured with a particular speeder spring which influences in certain margin governor’s dynamic behavior as well. In operation is permitted to adjust maximum RPM in certain margin according to procedure stated in OPERATION AND INSTALATION MANUAL. More important changes in maximum RPM can´t be done without retrofit of speeder spring.

The adjustment margins must be quite small
