Gap Clutch housing to Trans housing

[reedgmi]

Now that the weather has started to warm up, I've been working on cleaning off a few decades of oily grime & dirt from my new-to-me 1010C before doing a full round of oil changes and some other small things. Unfortunately ...... I discovered this small gap between the clutch housing & the trans housing. A bit less than 1/8". Maybe it has been like this for 20 years, I don't know .... but hard to ignore it now.

I understand there are 4 large nuts securing the clutch housing to studs in the trans housing? Which are likely loose.....
Is my worst fear right, that the only way to access those is by removing the final drive? Or, any slim chance of hope that they can be tightened from above, from the top access plate?

Final drive needs to be removed, don't use the crawler til you fix that, big dollars if you don't.

Upon closer inspection ..... tightening up some nuts is the least of my concerns. The clutch housing is cracked.
Probably because the 3 bolts to the frame rail are completely missing.

So .... housing must be replaced. Are these relatively easy to find? At this point, I'm thinking it's still worthwhile getting this baby running again. I hope.

They are around, I might have one, either way, you can't run it the way it is other than risking catastrophic failure.

Agreed, just gotta get into it, see what I find. Once I get the track off ....

Can those cracks be welded and repaired?

I have been wondering the same. Need to get it disassembled first and see the full extent of the damage.

The housings are cast iron, so they don't weld easily, and unless you are skilled at cast welding, usually expensive.

Yeah, I would not attempt it myself, but I know it can be done with correct preheating / cool down procedure & good filler rod choice. Since I'm close to Detroit, there are options close by to work with. Would boil down to cost of repair vs. cost of used part+shipping.
