  • Re: PTO
  • It seems like Iíve seen the part with the spring seal deal. Good luck with your repair.

  • Do you mean the 9N-733-B housing? The parts books show one, the "B" suffix meaning there was a 2nd revision to the original. Are you certain you have a 1939 9N and going by the serial number? Where did you buy your parts from? Many here use one of a handful of reliable Ford Tractor Parts suppliers like Just8Ns -see LINK.

  • Re: PTO
  • Tim, the PTO shaft on fig-7 is the one that is in my 9N. You can see the spring and all the other stuff I was talking about on the shaft and the different kind of housing. The PTO shaft and housing below that, is the one that I thought I was going to pull out of my 9N. The PTO shaft with the spring and housing, what is it suppose to do?

  • Yes, that is the early shaft. You may not be able to get parts for it, I don't know. Call Derek Barkley at JUST8Ns and ask him. You may need to buy the whole new 1-3/8" style.

  • Re: PTO
  • Tim, the PTO housing that I pulled out of my 9N has a friction disk on the backside of it. I looked at your link. I have that housing that I ordered off of eBay. It does not look the same so I was wondering do I need to upgrade my PTO shaft and housing? All the ones Iíve looked at on the Internet do not have this friction disk on the back of it. There is a C clip, a metal housing, a spring rubber seal with retainer for the spring and a brass disk. The housing looks like it has some sort of smooth surface, like a fly wheel.

  • Re: PTO
  • I don't know, no brass 'friction disk' is used nor listed in the parts manuals -see LINK below. It is from 1946 but shows both the early 1939 PTO assembly and the later one. Tell us what you have and which part you are referring to. The original PTO splined end was 1-1/8" and later the AG engineers made it 1-3/8" which is the industry standard still today. The parts sold today will fit either shaft. Also go to our MANUALS forum and look under PARTS, open a MPC and look at the exploded views and part descriptions. The bearing housings, shafts, and most other related parts are probably made by a few suppliers. You don't need to buy off ebay -usually don't know what you might get. JUST8Ns, Dennis Carpenter, or STEINER are a few of the handful or reliable parts suppliers. there are 2 snap rings, a bearing, seal, bushing, and a paper gasket in the PTO rear bearing housing. Pictures would also be helpful. Look at Page 22 in the January, 1946 MPC - see LINK...
