Allis Chalmers HD7G Crawler - seal leaking

The torque converter output shaft seal on my HD7G A/C crawler/loader is leaking.
Has anyone ever changed this seal from the bottom?
Any tips?
Thanks

Do you have a good Drott 4 in 1 blade assembly with hydraulic controls for sale? How about an aspirator for the later turbo engine?
I have my manuals now, just need some warm weather to get some work done.
It would be easier to get at the seal that way, but I do not want to remove the engine assembly.

I am sorry I do't have blade and if you had the part number for apirator for turbo engine I could check and when you change the seals make sure the retainer bearing is not worn because he will leak again.

If I find play in the shaft when I disassemble, I'll post asking for instructions.
The service manual I bought on eBay is actually a parts manual.
Thanks
