9N pto seal repair question
I have found several "how to's" on the newer 8N pto seal replacement. but the diagrams of the 9N seal arrangement look much different than the 8n.
Is the 9n pto seal removal/repair/replace significantly different from the 8n?
The diagrams seem to show a ring of packing and not a "seal" in the 9n.
Help!

Only if the original 9N PTO was replaced or upgraded. The early machines had a "funky" seal assembly. Check out this web page for information:

My suggestion if you still have the old PTO style shaft is to replace the whole thing. It will come with an 1-3/8" PTO and a normal lip-style seal. If your trying to keep the outside of the tractor looking original, I hear that you can switch out the new steel bearing retainer with your old cast iron one. Not sure if any modifications are needed though.

Thanks for the info, learn something new every day..
Seems like it applies to the '39 to'43..OP take note..
Altho I leave my ORC on all the time, I would consider upgrading to the 1-3/8 also..

When you go to do this... you're liable to loose a whole bunch of your hydraulic/transmission/differential oil.
Unless...
You can park the tractor with the front wheels in a ditch (or some other means of lowering the front end) causing all of that oil to pool in the front of the casting and change your PTO shaft out like that.
Of course... if you get it at too steep of an angle... you'll find out if the front seal in your transmission is leaking, too... :hide:
