    bracket repair

    I was going to replace my block because the ear that the ps/alt bracket mounts to was broken off. after some measurements, my block is totally in great shape other than this stupid ear, which causes one of the other bolts to break off.

    I was thinking about bolting it up this time with large washers for the other 2 bolts, and using some sort of bonding material wherever I can get contact.

    or maybe trying that castaloy stuff. any ideas?

    I wouldn't feel safe unless it was welded, but I haven't used any sort of metal putty for anything structual like that. If it was me, I would pick up a 69.95 wal-mart special welder and weld it.

      as far as welding cast iron goes, I think some sort of epoxy would be better. plus the braket is cast aluminum.

        good luck putting a weld that holds on with a 69.95 welder. call a mobile guy to do it.

          Has welding cast changed? I know you used to have to bake it in the oven, weld, then cool slowly, and that usually doesn't even work. is there somthing new I am not familiar with?

            no, i was just saying that even if you tried a 70$ welder wouldn't give you a strong weld. I believe you can weld cast with a MIG no? im not really sure on all the metal properties, but i know i got my cast shifter plate welder, and its held up fine. that was alluminum tho... so im not really sure. if you can weld it, you will want somone with experience.

              That's different, that's heliarc welding... cast iron is a pain in the ass.

              I've read about drilling and tapping holes for steel studs in cast iron pieces, then using them to weld the material back together. Not too sure though, as I've only welded steel.

                Well, I think I am just going to try some jb weld putty, then drill and tap. I should be able to improve the strength of the repair if I make it right... so I'll let you know what happens when that is done. worst case scenario, It fails, and I have to swap just the block. let's hope this works...
