1989 Morse Command 2 rotary helm with cover plate removed. http://www.c-brats.com/albums/Adeline/Morse_Helm.sized.jpg . I'm not quite clear how to proceed. I know that the 2 machine screws at 7 o'clock retain the anchor plate securing the cable end. But the white nylon "back-up ring"(between housing and rotor) seems to require removal before the cable can come out. Also, it appears the cable is under great tension as it enters the housing. Do I have to remove the entire helm assembly to relieve this tension or can I muscle the cable in/out with the assembly still bolted to the bulkhead?
