MH tranny/differential model 20 (or 81-82-22) ???

Crazy Horse · Aug 14, 2017

I see the spec sheet for the Massey Harris models 81/82/20 and 22 show 16 US quarts of gear lube oil for the differential and another 8 quarts for the transmission. In a manual I have, it says that the tranny and differential are separated by a "wall" but I don't know if the two sections are actually sealed off from one another or just sort of "separated" but maybe continuous for oil use. I think both have their own fill plug on top (the tractor isn't here right now so I can't check that for sure) but I now the tranny has an oil level check plug on the left side and the differential has an oil level check plug on the rear.

So then, why am I asking? Because underneath, I can only see one drain plug. Are the two chambers totally separate and sealed off from one another inside the tranny/differential assembly?

If I remember right in my 205 industrial they were shared. Been a long time since I had it apart.

I recall seeing a seal on the parts list of my Mustang 23, it has two oil levels too.

Thanks for the replies boys ..... I am going out tomorrow and will see what is what with fill holes, level check holes, and drain plugs. Trying to do it from memory is tough. I'm just trying to figure out exactly how this whole set up works, I really don't have any problems or issues.
