I've been doing some more prelim work to prep my Kadett for the upcoming 'sprint
' installation. I was checking the remaining pieces of the accelerator linkage that's going to stay in the car when I do the switch from the Solex to the twin DFOs and noticed that the main pivot bracket actuated by the accel pedal had a bit more slop in it than I wanted, even though the pivot bar was replaced after failure (post #1
) a few months ago.
Took a closer look at the pivot bracket and saw that the pivot hole was a bit out of round, probably contributing to that earlier failure. Even though well greased, this link would slightly bind at times and cause the accelerator pedal to hang up somewhat . . . not a good thing in view of my change to dual carbs in the near term.
Went to my favorite hardware store and rummaged through the section where they keep all their "odds 'n ends" . . . rifled through the bushings box and found a thinwall bronze bushing of exactly the right length and ID (.25"/6.35mm) required to "bush" the bracket pivot back to proper, round size . . . pivot bar is 6mm OD, remember, for .014" clearance. PERFECT!!
Hurried back home, trued up the bracket on my drill press for align boring the hole for the bushing and "step-drilled" it up to the size required for pressing the bushing. Lubed it up and reinstalled everything . . . smooth as a baby's behind now!
