H PTO sizes

oldnnew · May 27, 2010

Hello all,

I have a 1940 H that has the newer style PTO installed. It was originally equipped with the smaller diameter PTO, but was removed many years ago due to the shaft breaking. A few years ago I decided to re-seal the trans and replace a few bearings. While I was in the trans. I installed a newer counter shaft that would accept the "splined" style PTO. I have recently found the old PTO housing and would like to bring the tractor back to original by installing the old PTO with a new shaft. Since I have installed the newer splined style counter shaft, is there a splined style "old" style PTO unit out there somewhere? I seem to remember seeing a listing in the nnalert tractor parts catalog listing 3 styles of PTO for the H. I hope this wasn't too confusing to read, and if anyone could lend any advise, it would be appreciated! Thanks.

Yes there is an old style splined PTO with the small PTO shaft. I did that on my 1940 H that had been changed to the new style years ago when the old one broke. I might have a slined shaft but I would have to look first.

Alvin, if you have a splined shaft I would definately be interested. Let me know.
Thanks!

I have splined PTO shaft I would be willing to sell, It is the small diameter on the out side with and adapter for the standard size on it. I would sell it for $45.00 plus shipping or you pick it up.

Just to confirm, I can simply remove the newer style PTO assembly that I installed years ago with the splined countershaft, and just slide in the old style smaller PTO assembly? There are no issues with the countershaft in the trans matching up with the old style splined shaft? Does this shaft that you have, have the mounting flange? If not, that's ok since I still have the original one from my '40 H.

Where are you located?
