Sheared bolts on bore plate?

    My opinion, not that you want it, would be that since you're so close, pull the track frames, put in new bushings and new spacers, grab a buddy to help get the track frames back on(I usually find the offer of some kind of meal with beverages helps),grease the snot out of it, and head back to work without a worry of it breaking again....at least for a while. Grease is your best friend with that setup, I wouldn't be afraid to grease those axles every time you use it.

    92U3406 also mentioned the possibilty that the torsion axles might "spring" a touch when the track frame is pulled right off. That could obviously cause difficulties to get the track frame back on the axles again.

    Depending on which way the weight is biased on those axles, one or more small ratchet straps might be just the job to hold them in place against the forces trying to move them off-centre and make slipping the track frame back on again a doddle.

    Axles with some hours on them are a little easier to manipulate. New ones suck. It definitely takes some muscle to manipulate them. I've had to use soft slings and comealongs to get them aligned to go back on sometimes.

    I've replaced a few of those axles and, for me at least, the track frames slid straight on. YMMV.

    Back to the original post, I suspect that wear isn't what caused the broken bolts. Why do I think that? Because the grease fittings have been broken as well.
    I suspect the retainer was sheared off by a rock or something.

    I tend to agree. I think the bolts are crap--all of them are rusty with significant thread wear. No matter what I was going to replace all the bolts.

    I've been re-reading the post and I'm a little confused when we talk about spacers. My understanding is there is only one spacer--the one on the inside. On the outside there isn't one--just a split bushing and the cover plate. Is that correct?

    I figured it out. No outside spacer.

    Those grade 8 bolts are tough. I can't get a drill bit to make any progress.

    Maybe a short length of thick-walled pipe just small enough in diameter to fit in the hole, then slide a welding electrode down the inside of the pipe and weld the pipe to the bolt. Allow things to cool and hit it with a pipe wrench, you might get lucky that way.

    I got them drilled. One came out with my speed out. The other was a SOB. My speed out actually snapped off inside. Kinda of screwed now. Nige, your idea of welding a pipe might work. I was actually considering welding a whole stud in there and putting a nut on it.

    So long as you don’t blow through the wall of the pipe (that’s why it has to be thick-walled) while welding it should keep from damaging the threads as you screw the whole shooting match out. If you want you can weld a nut on the end of the pipe.
