  • 40 chief center stand castings - Frame Lugs

    I broke my center stand castings (on the frame), the other day when I thought I could start my bike and stuff on the stand. Lesson learned, Ive now been advised not to do that as the lugs will inevitably break. I am now looking for some castings information so I can order them and I can have them re-welded. I have scoured all my literature and all the regular sites that I know about and can find no information.. Does anyone know the numbers or information?

    It was so long ago I didn't have a digital camera, NiteOwl,..

    But since the whole frame is speltered into cast iron members, I built the lugs back up from scratch around an aluminum rod, with air-compressor piston rings for filler.

    I believe it is still in service, and hope to see my friend again at D-port this year,...

      I am hoping you were able to find the broken pieces?
      I am wondering if they could be brazed back in placed? Not as strong as a weld but perhaps . . . perhaps enough.
      On my 46 the left side center-stand "tab" was missing but thankfully Geer's sells just a Center Stand tab (Indicates to me a lot of them must have broken off over the years)
      I was able to grind and braze this tab for a decent fit onto my 46 center-stand. Fix has lasted ~ 3 - 4 years now.
      Good luck, let me know what you find.

        YES, I do have both pieces as they had just curled around and dropped the stand to the ground when I tried to use it at home. "Lucky it did not drop while ridding". But the good news is I have them, removed now and they look like someone might have welded them before and did not get penetration, I could be completly mistaken though as it maybe the cast fooling me. I can braze, I am also wondering about Cottens method, I dont have any old compressor rings laying around. . . and I have checked and they are cast. I was originally searching for new castings but that might turn into too much of a job thats not necessary as It looks like I would have to cut the frame etc to put them in, WAYYY more work than I want to do as I ride this everyday.

          Excellent! Somebody up there likes you!
          I live in the northeast and would look at this as a 'winter project'.
          Ride now and enjoy while planning for repair.

          Cotten certainly has a lot more knowledge and experience than I do.

          I did have a bit of luck brazing in some 3/8 steel to repair some "buggered" axle castings on my 741:
          AFTER and BEFORE pictures (I'll get the hang of this tech someday)
          I should have taken pictures BEFORE painting but who knew I'd be posting!

            It's cast iron, Folks...

            That's why I fixed it with cast iron. But also why it broke in the first place.

            If your welder has the skill, silver-soldering Greer's lugs (guessing that they are steel), could conceivably be stronger than the original.

            Feel lucky? Sounds like a plan to me...

              Didn't see lugs on the Greer site, Folks,...

              And most common piston rings are cast iron, NiteOwl, I only used what I found because I had no other use for them, but even used motor rings should do.

              Although I'll blame the cheesy effect of this Model DC repair upon oil contamination, rather than my lack of experience AND patience.

              (It was completely missing above the arrows; I saved and carved threads enough to run, but I can always Helicoil it if the customer wants to invest more into it.)

              Here's a broken cast iron lawn furniture lug that turned out a lot prettier...

              These were Oxy-Acetylene torched. Nobody's ever let me touch a TIG.

              The pro's all insisted upon silicon bronze or nickel rod; Carving those fillers to shape is.... expensive.
