Front ram air heat exchanger control cable

[raykenyon]

Hello Herb--

I have a new replacement cable---the old cable is completely removed--yes, the cable controls the ram air valve in front of heat exchanger that passes turbo air into the janitrol unit.

It is the "routing" of the cable from the heat control levers at the bottom of the copilot instrument panel--through the front bulkhead and through the engine compartment to the ram air "butterfly" valve---that I can find no info on.

I am confident Cessna had a specific (safe) way they installed this cable and I want to put the new cable in correctly.

Thanks for your reply.----Ray

Ok, if we are talking about the cable on the valve off the Janitrol Heat Exchanger, it runs down 1st attaching to an arm off the exchanger, then back to the battery, then up to a point on the firewall midway between the vacuum pump and inner (lower) starter contactor (should look like a quarter with a hole in the middle). Then thru the bottom of the avionics bay and into cabin behind the center console then parallels the defrost cable to the lever. FYI, mine is a 73.

Hey Brent-

didn't get down to the hanger today--plant problems--tomorrow I hope--cable goes back to the battery box--under the battery box?--and makes a 90 degree along the front bulkhead?
