Farmall A PTO seal replacement

Fluid was leaking around the PTO shaft on my Farmall A. It sounded like an easy fix. I got the old seal out and then another "seal" I think, as it had a spring of some sort in it. I also was trying to get another metal piece out that was on the very outside of the round cast part of the PTO. I completely mangled that piece and then it hit me that I probably was not suppose to take this piece out. I would appreciated any help and advise on what this piece is, on whether it was suppose to come out, how do I get it out and what do you call it so I can get a replacement part. Thanks for your help. [/img]
 
The current seals are much thinner than the ones in the 40's/50's. Sounds like there is a 2nd one. All of them have springs, just dig it out. Some think two slow the leaks, maybe or maybe not. If you get the other out you should see the bearing--hope you aren't digging that out.
 
Ignore what I said, I did not read the mangled outside piece correctly. --I have to look at mine to explain it.
 
I had to disassemble my Super C PTO to get
the old seal out. The original ones are
some much larger and layered, so to speak.
Drilling, prying and pulling only got pieces
loose. I couldn't get the seal shell to
budge till I pulled the shaft/bearing from
the housing and drove it out backwards.

That's the outer shell of the old seal that is stuck in the pto casting. I had to take mine all apart to clean it out. Those old Chicago
Rawhide seals are built really tough.

Good Luck

Thanks that is exactly what happened. What I could get out came out in pieces. Looks like I will be taking it totally apart.
 

Thanks for the information. I am glad to hear it was part of the original seal and not something I wasn't supposed to take out.
 

Had to take the PTO and casting off the tractor. Ended up taking the PTO shaft out and then with a lot of persuasion, blood and tears it finally came out. I appreciate the advise. Thanks Dave BN, Chris NW Ind and CNKS.
