 Topic: Broken Bolt from loader mount D-15
Posted: 01 Aug 2019 at 5:14pm |
|
I recently took the trip loader off my D-15. (It looks better without it) but eventually it will have to go back on as Its my only loader. Anyway I had a broken bolt in the side frame which I drilled and removed quite easily. I also have a broken bolt in the rear axle houseing (cast)... it is broken off flush... what is the best way to remove it? Drill it out? or weld another bolt on and see if it will back out? I have been spraying it with blaster everytime I walk by it.....? thanks

Many variables in broken bolt removal, If you can post a few pictures, it will help. Also, what equipment you have and your experience level will play into the final decision...

If possible weld a washer to the bolt if flush. Then I would weld a nut to the washer. I Have been able to remove a few that way.

Some times....some times
I have used a die grinder and dressed down a cut off wheel to about the size of a quarter or so....grind a slot into the end of the broken bolt...then you can put a big screw driver into the slot and SOME TIMES you can back the bolt out
Before you grind the slot...if you can whack it good a time or two it will help also
Or use an impact driver with a screw driver head on it...then you get the whack and turn at the same time
Once it moves you should be able to turn it on out with a regular screw driver
I like screw drivers with square shanks so you can put a crescent wrench on it to help turn....but keep the pressure on it to keep it in the slot
Impact driver if you can get to it to whack it

Richardmo method has been the best for me. A very good way to put heat to the cast to break the rust bond. The heat seems to transfer down the broken bolt better than using a torch, but that is only a guess on my part. But yes in some places almost impossible to access. Good luck, cause luck is much easier than skill.

You won't hurt it with heat.

My theory is that when you weld a nut and/or washer to a broken stud in a cast iron block is, steel when heated tries to expand in all directions but can't expand sideways because of the cast iron, so it expands a little more length ways. Then when it cools, it shrinks from all directions.

You won't hurt the cast by welding a washer on the broken bolt. Clean up the weld and weld a nut on the washer. The nut doesn't even have to be centered well on the old bolt, but doesn't hurt if it is I have blown broken bolts out of cast with a flame wrench before and seen it done many times, just no fun on a blind hole.

got it out. cleaned it up good and welded a nut on it... it kept twisting off, took about 4 nuts to get it a 1/4 in. the last nut we were able to back out the rest of the bolt. Someone BEFORE me had tried to get that bolt out before... there was a broken off easy out inside the broken off bolt. tried a picture but no luck

If an easy out will get one out, it wasn't tight anyway! JMHO, Tracy

the easyout was broken off inside the broken off bolt from an earlier attempt to remove it. I wish I could share a pic. we didnt use an easyout. we welded a nut on it. The nut kept twisting off so each time we welded a new nut on and kept trying. finally got it.

Easy outs work great on a bolt that isn't buried in a blind hole. Sometimes the wrong bolt is put in a blind hole and the threads get locked up in the bottom, where the lead is on a tap. They can be a bugger to get out, and also are more prone to break, if the head isn't holding tight like it's supposed to. Brian, did I see a fuzzy pic on facebook of the broken piece?
