    @rollin coal , if you have any decent size flat washers, take 1, weld it on as close as you can to the flywheel housing, let it cool. Weld another, let it cool. Weld 1 more on. Let it cool then id weld the nut on and try to back it out.

    The heating and cooling can be really good at loosenin up a broken bolt. I have done that many times on broken exhaust manifold studs.

    Good luck on that one man.

    Got it this time. Welded the nut on there good then heated everything up as red as I could get it with my propane torch. It backed right out... whew!! That has been on the back of my mind for 5 years now bothering me now it's fixed.

    So that's what that tool is for! I've had one of those in my box for 15 years. Always wondered what it's real purpose was.

    I hate to say, call CAT and price one make sure you're sitting down, lol. But you know what I don't really care. It's a good tool that works great for that job and whenever I need to change a starter it'll be a quick easy job. Pic of the broken bolt. 39MT sounds funny compared to the old 42MT but it works and doesn't go click, click, click...

    I just removed a Denso R5 gear reduction starter I bought brand new a few years ago for $380, I missed the power of my old 42MT. So I had the 42 rebuilt at the local electric shop for $280 and installed it. MAN!! did I forget how heavy that thing was to manipulate into position.

    For all you guys that prefer the 42MT's I have a small tip for easier installation. Stud the top hole and when you lift the starter into position it will stay in place and leave your hands free to get the bottom two bolts in.

    That's a great idea. That 39MT being 20 lbs lighter was not that bad installing. I was easily able to hold it up there and start the bolts. It's a few inches shorter than the 42 and doesn't have that snout protruding over the gear.

    There's nothing wrong with my 42MT other than the solinoid was bad. I read some comments in here by @swaan about bypassing it? But I'm not really sure how to do that. I thought I'd just get a new solinoid and put back on it then keep it on a shelf. It gave me several years of good service.

    You can get a new solenoid for 60 bucks. Id put a new one on it and keep it at the ready.

    Yeah I already priced them. That's the plan.
