    Speedo and Tach cables stuck R75/6

    Hi there. I was trying to remove my dash to repair a broken trip reset knob, and I hit a snag. It seems the threaded studs, where my speedo and tach cables attach to the back of the dash, are loose. So, when I try to loosen either cable, the stud just spins. Hence the cables are stuck (for now). Has anyone encountered this before? Any suggestions to hold those studs so I can unscrew the tach and speedo cables? Thanks!

    From memory on my /7, there is a thin jam nut. If you see that, you'll need to get a thin wrench in there to hold it. See this #3 for the speedometer.

    If that doesn't help, you probably need to lubricate lightly in this area with a penetrant.

    I was replacing the cables on my /6 anyway, so I cut the collars with a Dremel and split them with a wedge in the kerf to brake them free of the housing. Kind of an adaptation of how one removes stuck exhaust nuts.

    Closing the loop here, a small needle-nose Vice Grips worked to hold the threaded stud while I unscrewed the cables.

    When YOU are in N.W. Georgia, find your way on Hwy 136 outside of Calhoun, to my mountain top. Camp or RV awhile up on top of the hill and find the peace that I do..........God bless
