I have a Dearborn PTO Extension Kit that I am wanting to repurpose to drive a Transmix cement mixer. I have the Mixer's drive cylinder mounted to the PTO extension on the 1 3/8" shaft then I discovered that the drive end of the extension kit that connects to the tractor is an 1 1/8" PTO Shaft. My Plans are to mount the mixer on my 8N that has an 1 3/8" PTO Shaft. What are my options? Does anyone have a Dearborn PTO Extension kit that is 1 3/8 on both ends? Can I install an 1 1/8" PTO shaft in my 8N? (Not my preference).

Your 8N came from the factory with a 1-1/8" PTO so a previous owner has upgraded your tractor, and you could go back to that.

eBay has a variety of 1-3/8" x 1-3/8" PTO extensions.

Is there a difference between the 1 1/8 PTO shaft for an 8N versus a 9N or 2N? Many of the shafts on ebay indicate that they came from a 9N or 2N.

We have a 1949 edition of the Ford Tractor dealer parts book here in our Manuals library that you can download if you like.

The dealer parts book shows one for 2N's and 8N's ('43-52) and a different one for 9N's.

I have 3 but will need to check PTO sizes.

Expect ahat all are 1 1/8" to 1 3/8", as are most.

Thank You

Two of my PTO extensions are 1 1/8" to 1 3/8". The other is 1 1/8" both ends.

Thanks for Checking Dean. I need 1 3/8" on both sides to accomplish what I need. Sounds like I will be converting my tractor back to the 1 1/8" size PTO Shaft.
