Here are a few threads for you to take a look at. Hope they give you some ideas about what is involved.

Great info. That's a huge help.

I'm going through the parts diagrams trying to make a list of all the gaskets and seals I need.

you could drop an iron rear in there and never worry about it again. like what i did.

I agree! Did the same with my 1872.

Would these iron rear ends bolt right up to my 2072 or would they require modifications? What model cubs have iron rears that would fit? If I stumble across one, I may consider it. I've been looking a lot, but these types of things are harder to find in my area (Louisville, KY) than I thought.

I've found a new axle carrier as well as a rear differential housing on the net and just waiting for them to arrive in the mail the next few days. Hopefully, the housing will not have any issues with the threaded holes. I plan on using Sam Macs rear end rebuild thread as a guide. I only want to do this once!

Just my 2 cents but if all you need to do is replace an axle tube and maybe put an insert in that bolt hole I'm not sure I'd do a case swap. In order to put a cast iron rear in it you need to find one out of a 982 or transplant all of your internal parts into an iron case. No matter what you do down load the service manual from the tech section so you know what your dealing with.

I've been referencing the service manual and it recommends tightening everything to 360 inch pounds first and checking again for leaks. When I used a torque wrench set at 25 foot lbs, I couldn't get a few bolts on either carrier to tighten. I think a previous owner may tried to fix the leaks by overtightening. I may be dealing with multiple stripped holes. I'll post what I find when I into it and see what advice you guys have.

Also, I can't find a gasket in the parts diagram that goes between the hydraulic transmission and the adapter housing. I would think there has to be one.

Yep they make it hard to find that gasket The cork gasket is item number 2 if you look it up on the Cub parts site under drive line, go figure.

GASKET Part Number: 721-3004

Got to agree with this fix.Fully intend to do this to my 2072 and have the cast iron rear already in standby even though mine is still in good shape.Have read where it adds 50 lbs to the rear as a bonus.Must be the reason mtd went back to iron cases again.

the iron rear has some good weight to it. i was able to pull the aluminum rear out and carry it 75' to my work bench. when i finished the swap i tried to lift the iron up.... not. i was left with a fully assembled rear on my work bench saying, "how the heck am i going to get this thing out of here". it wound up weighing 170lbs.
