Super A transmission.

Postby Big Mike » Wed Feb 28, 2018 5:29 pm

The PO of my Super A apparently ran it for some time with the PTO shaft seal leaking and as a result, there's very little oil in the transmission. I'm about to replace the seal (as soon as I learn the number). How much oil does the transmission hold and does anyone have an idea how to remove the old seal other than a cold chisel and a hammer? I've found what I'm assuming to be the fill level plug at the bottom left corner of the serial # plate beneath the seat. It is a slotted head plug (use a screwdriver to remove). Am I correct? Thanks in advance.

I did mine so long ago, and had help, that I can't really remember much except that that sucker was a real PITA!!! Here are some photos that I took...maybe they will help:

The slotted plug holds the spring and ball for the PTO shifter. The level plug is on the left side near the front of the transmission case. It is very near the left brake rod.

FYI...If I did this right, this is a link for the Super A Manuals (from Rudi's old website), if you do not already have them. (Thanks to Dennis, I think, for saving them!!)

I did mine from by taking off the gear on the inside and I wouldn't recommend doing it that way unless you have another one for spare parts. And you can't use heat to remove the gear because they're special heat treated and you'll ruin the temper if you do. I think doing it from the outside is the best bet, just don't crack the housing.
One think I've always been impressed with is the Farmall heat treatment for gears, hard as glass but not brittle. The best I've ever seen.
