 Topic: oh,oh. broken bolts in a C
Posted: 25 May 2020 at 12:57pm |

Must have been a little to rough on my C. Could hear the fan hitting the shroud when I hit a bump. Turns out I broke two of the bolts holding the front end on. Two of the four bolts out the front of the block. How tough will they come out? Are they just tightened in there or are they lock tightened with some thread locker? They broke off just inside the block.
Good time to overhaul the front stem which has been a little loose, maybe that had something to do with this?
Any advice is welcome, Thanks in advance. Stephen.

Yea, i would guess the bolts were loose.. Hard to break if all are tight. Couple loose and you overload the others.......... If they have been LOOSE, then you might be able to use a small punch and work them around and screw them out.. If they dont move, set a 1/2inch nut over the broken stud and weld down in the hole so it grabs the stud to the nut... also the heat will break down any rust... then use the nut to screw the broken stud out.

Shouldn't be loctited, but one never knows what the previous mechanic did. Center drill and heat. Let cool and try an easy out. If it has been loctited the heat will break it loose.

Center drill, using LH bit. THere's always the chance, that you can back the bolt out... If not, easy outs, and if that don't work, weld a washer to the busted bolt, then a nut to the washer, etc...

Weld a flat washer then a nut. Gives more area to weld around the outside of the nut

Unless you have a heavy wire feed welder, I'd use a stick welder to get better penetration down into the stud

I think if you two of the four are broken and the front end moved enough for fan to make contact the others are probably loose too. Support the front end before going much further trying to remove, we all tend to get a little single minded when fixing something and can get away from you quickly if too loose.

Well, I got em out, one came out with an extractor, the other extractor broke off. Haven't spent so much time in a hole since my Honeymoon. The block plate made it hard to get close to the bolt. Torch was the savior.
I think this was broke a while, finally loosened the other two when I used it to pull a tree down. The tractor was used for pulling and I think he had weights hanging on the tool bar on the front end, and these little Allis are notorious for doing wheelies. Thanks for the response, wish I would have read about the candle wax before I put the extractor in, once you put that extractor in you are committed, it either comes out or the extractor breaks. Thanks again.

If it breaks down in the hole, as usually seems to happen on me, I started skipping the extractor step because they break so often. I keep drilling as much as I can before hitting threads. Then go at it with little triangle files until I can either get it to spin or start breaking pieces out.
