What's the diff ?

Thanks for the info. Wondered if you welded up the bore so you could re-bore it and use the same size bearings.

Got some more pics and a couple vids today.

First pic is showing top front frame bore being welded. That's a 10" diameter bore , 8" thiick !

Meanwhile, welder is repairing cracks and cutting out and replacing a cracked fishplate.
Machinist managed to get a 8ft bar in between rear frame bores but a very tricky process. Had to pre install 2 bearing blocks then feed shaft through bottom bore then up through top. Add the 2 end blocks and get things all lined up.
Due to tight space under cab the 8 ft bar is not long enough so after everything was set up he managed to have enough space to remove the long bar and then do each set of bores with a short bar.

If I wasn't a mechanic, I'd love to do this machining work.













This pic he's just setting up the welder which anchors to the rod seen.

He takes a cut, then welds, then cuts again to finished size.

Cool stuff Mario. I need a boring machine to clean up the boom pivots on my mini excavator. I think that one might be a bit too large though.
