New 8N Owner - New Problem (for me at least)

Hello all! Last week I purchased my 1st 8N, a 1949.

I did a bit of research on 8Ns before the purchase and feel I got a fairly good example for a fair price. Purchase was from son of PO and didn't know much about it or how it was used other than it had been in the family for 20+ years.

I have been lurking and trying to learn more about these tractors from the collective brain trust here. Obvious goal is to safely maintain and operate the old girl.

Fresh fluids and a carb rebuild have it starting and running reliably and I moved on to the 3pt system. PO had an incomplete set of drawbars and there were some bars/brackets attached to the rear axle from an unknown implement.

Attempting to remove these brackets exposed a slight problem; the lower left lift rod attachment pin spins in the casing and I can't get the nut off to attach my lift arms / drawbar.

I searched through the forum trying to find a relevant post to no avail. Any help would be appreciated.

That pin is a taper fit with a castellated nut and cotter pin holding
it tight on the inside. If it spins, it will leak there as well.
Unless there's no oil in the rear end.
It's not a tough or expensive fix normally, but does require pulling
the axle trumpet. Since yours is the left one, you can pull that
trumpet and the pinion gear assembly to reach the right side too.
 

If you're going to fix this I would buy 2 new pins. If they've not been replaced they are usually very worn and fit very loose. As stated if you pull the left trumpet you can remove the ring gear and carrier and access the rt. side too while you're in there. Of course to pull the trumpet you'll be removing the wheels and axle along with the brakes so you'll be checking and resealing all of that too.

o need to remove hub, axle, brakes, etc. Just whole assembly together.

You can pull it like that but it's a new to you tractor that's only 70 years old. What could be old or worn out?
 

Actually I intend to purchase from here in support of the site, I just don't know if I should get the original Manual (reprint) or the I&T version with electrical.

I also intend to get the Operators Manual and the Parts Manual once the decision on which Service manual is made.
 
I have both an original (original) and the I&T. They don't always
agree but both give you different pictures and perspectives.
I don't have the reprint so I can't speak specifically to that one.
The original operators manual has information not readily found
in either of my service manuals, so it is a great addition as well.
The parts manual is available online from [b:688ba30da8]CNH[/b:688ba30da8] Some parts are NLA.
