UPDATE:
Spoke with my local support (who's delayed till tomorrow) and he's said to simply leave the bucket on the machine for now as Tugger2 instructed.
Today, I'll get the side cutter off by splitting the nuts and will continue cleaning the area up.

Thank you all,
E

What have found with heating is removes any entrained or absorbed moisture, that generates steam pocket inclusions and a bit of Hydrogen from the arc process which adds to embrittlement.

Oh, yeah right.
Thank you,
E

UPDATE:
That worked out very well.
Thin cutting disc straight across the nut & bolt face. Hammer and they popped out. Cutting edge is off.
Thanks again,
E

Can using the teeth on my bucket to break up concrete with the bucket curled all the way back cause damage to the pins or other parts?

Hi Cowboyrob,
You'd most likely want to start a new thread based on this question but the quick answer is...
Surely.
Besides the pressure on the front edge (teeth) the pins, support plate welds and bushings are going to take a real beating, especially if you're hammering the bucket down to break the concrete up. The torsional loads on the pin supports are really high when the teeth are used as leverage and cracks may occur at the pin plate welds. Ask me how I know...

Bottom line, for the most part, the bucket is meant for 'bucketing' not hammering, like a hydraulic hammer is.

Seems like you do it similar to most of the rest of us ;) if you're breaking up slabs that you can lift a corner of just lift em' and shove something under the corner then come down on the center of it with the heel of the bucket... saves you teeth this way :)

Had a good long welding session on Sunday and buried a bunch of 7018. No support plates at the moment but should hold up just till I finish a few more tasks, then pull the bucket off for the winter, get it powerwashed and inside and go for a much more intensive repair.

Thank you all very much once again,
E

Why not fix it right the first time? I would have beveled if from the outside, pushed it together and welded the inside first. You could put a couple extra passes to add extra meat on the inside. Then grind from the outside into the root of the weld from the inside to insure 100% penetration. Taking the bucket off and putting it on its side would make it easier to weld the outside up. If you have any slag pockets or lack of fusion could be a potential source for new cracks. Preheat around 300-400 deg's. is sufficient.

Simply didn't have the time and needed to finish the remainder of the project this week. The machine will be sitting idle for the winter soon enough with plenty of time to it better.

Will be a better repair and inspection once you have it back home. Just ignore nothing as to an indication that could be cracking anywhere.
