I have had the cabin heat valve for almost 2 years, and it has been placed on the firewall for at least a year. I've also had the push pull control for it. The hole in the firewall has been drilled for it. So why is it not done? Great question...
The actuator for the valve is on the firewall side and moves horizontally. So I need to do a 90 degree transition on the cable. I have had some rough mounts for this ready for quite a while, but never finished it.
So here is the contraption... bell crank arm to do the transition, that is mounted top and bottom off the firewall frame for the pumps, filters, coils etc. It just simply transitions it 90 degrees. Just has to go around all the rest of the crap.
The arm has an AN-4 bolt through the center. The rod between the bell crank and cabin heat box is just a 1/16" piece of stainless from the control cable. Not fancy.
Finished product... need a shorter bolt, and I ran out of AN4 castle nuts.
The cockpit control is a McFarlane locking unit, custom engraved. Works like butter.
Excuse the mess. Construction Zone...
