But thats the thing - it wore through from the inside. I believe this internal shoulder holds a thrust bearing. Thrust bearing went and it went right on through the housing. (first pic is half 1, third pic is half 2 which is in better shape but still some damage on the surface where the bearing seats)
If I start welding then the internal shoulder would have to be re-machined. After getting it cleaned up (a little at least), Im wondering how a new bearing (bushing?) will seat. Maybe ok.... it only needs to sit in there. I have some aircraft epoxy that Im wondering wouldnt seal the crack and hold the bearing in place. (its an aluminum filled epoxy from masterbond, so I need to see how it will expand with temp in comparison to the housing). Have used it on a number of other things with good results.
Although as I type this I think I saw a replacement housing for $45 ish. Better option.
Im looking at a gear, the housing, the bushings, some misc spacers/washers (some are plastic) and it would be in decent shape again.
Worth doing.
Will inventory and source all these components and then move onto the other gear box.
