2N Axle Pivot Pin

KirkWest14 · Jan 17, 2018

Engine is done but it's too cold to install it outside. Working on parts I can do in the garage. I ordered the pivot pin I thought was open to accommodate the hydraulic pump shaft. Turns out it was too short. Reading the archive posts it seems I should have ordered the 2N3126E. That doesn't look like it will let the shaft pass through and it doesn't tell me the leangth. Any help would be appreciated. I've attached a pic of my old pin.

[b:2c91d24870][i:2c91d24870]Depending on the yr. of yer 2N. Mine is a 44 2N, and this is the one I ordered, and used.
4 inches long ....OEM style....and accepts my 3/4 inch frt mount Hydrol. pump shaft.

Ordered this from YT PARTS;

Don't forget, to order the pin bushing!!

Mine is also a 44 2N. The old one is about 1/4" longer and went through the axle mount. The one I ordered will make it to the
back hole but just barley. Seems like with a FEL I'd want it to go all the way through. Yes, I did order the bushing too. That's
when I found out my axle was hogged out. I'll have to take it to the machine shop and either have it welded up and re-bored or a
larger hole and make a bushing.

You need the pin that is 4.25" long. Bore and sleeve the axle support is far and away the easiest.

Yes. That's my question. Where can I get the correct 4 1/4" Pivot pin with the bore that will accommodate a pump shaft?

Dose these axel pins have a grease zerk so they can be greased? I looked for one on my 8N, but couldn't find one.

"Dose these axel pins have a grease zerk so they can be greased?"

They do not. If they did, it would probably be on the wrong side anyways.

Sorry... I made a mistake on the 4" length for the axel pin!!! I said it was 4".....that is supposed to read... 4 1/4"!!!!

The listing I gave you IS, the one you need, and unless your shaft for the pump is greater than my 3/4" in circ.....your shaft will fit through the pin face, with room to spare !!!!
That 2N 3126E is the one that I ordered and use on my 44 2N!!!!!

YT has both pins in stock....in the YT parts listings!!!
This is the one you need!!!

Front Axle Pin - For model 2N up to serial number 167489. (Part No: 2N3126E) $65.69

The part number for the pin is 9N-3126E. None of the pins come with an opening large enough for the pump shaft - the center hole has to be enlarged to roughly 1". Have the machine shop do that for you when the repair your axle support. Here is how I repair the supports.[list:6d79cba2ec][*:6d79cba2ec] Bore the support out oversize enough to restore it to round[*:6d79cba2ec]Install a steel sleeve turned to a .001 press fit in the support. I make the sleeve with a flange on one end and counterbore the front of the support for the flange. That way the sleeve is held captive by the flange on the axle pin. [*:6d79cba2ec]Then bore the sleeve to 1.750/1.751.[/list:u:6d79cba2ec]TOH

Whoops - the part number is 2N-3126E aand your problem is the axle is egged out.

Same repair process for the axle except no flange on the sleeve and size the ID to be a light press fit on the bushing.

KirkWest14, other listings for 2N3126E say it is 4.5 inches long.
That may be overall length, minus the tab might make it 4.25.
I can't post a link to them here, but Google the part number.
If the hole is too small, it may be only the hole in the tab.
That's the way mine was anyways.
I'd make a call to the YT parts department and ask.

The 4.5" is the overall length. The length of the pin portion is 4-1/4". The hole in the flange is sized to act as a support for the hand crank - 5/8" or possibly 11/16" IIRC - and will have to be enlarged for the pump shaft. When you enlarge the hole make it well over 3/4" or you will wind up with the pump shaft rubbing on the flange which will eat into the shaft.

That matches my experience with my pin/loader shaft Dan.

Gary, that is not the pin for my 44 2 N bought new in May of 44. It has the flange for the bolt.

To the best of my knowledge the chronology on the axle pins is:

[*:b889ed2427]2N production started using a 9N axle support with the radiator support modified for the doglegs (brackets for dog leg through bolts). The pin (9N-3126)was the same as used on the 9N - 4-1/4" OAL, had no flange (100% cylindrical), and was retained with a special vertical set screw on the top front of the axle support[*:b889ed2427]Follow-on wartime variants were made with a much longer pin that extended 4" or so forward of the axle support to aid in hand cranking[*:b889ed2427]Production then switched to a pin (4-1/4" under head, 4.5" OAL) with a tear-drop shaped flange welded on the front end (e.g. 2N-3126E), a cutout for the flange was added to the radiator support, and a drilled and tapped hole added to the face of the support for a 1/2-20 retaining bolt[*:b889ed2427]Final 2N production switched to a new two piece stamped and welded axle support as used on the later 8N and a shorter (4" under head , 4.25" OAL) axle pin with flange retained as on the 8N[/list:b889ed2427]I have seen all of those combinations - whether they are all OEM or not is a matter for debate and there may be others.

I have welded one axle and bored it out I don't think I will tackle that again I will hunt got a good axle... I was into it 4/5 hr. plus the cost of tooling I charged the guy $100 just to re-coup some tooling cost but I had a learning experience... A retired machinist came over and held my hand while I did it

...

Hobo,NC · Jan 18, 2018

I would tackle some of the worn axle supports I have laying around BUT my mini mill don't have the travel for it

... Maybe one day I will get the real deal...

That my friend along with great unhappiness with maintaining setup position when adjusting head height on a round column mill (what idiot thought that was a good idea) is what sent me looking for something larger. I'll keep my eye open for a good deal in your neck of the woods.

PS> You have 3 phase power and lots of room for a machine in the Rosser Automotive B&B? ;-)

KirkWest14 · Jan 18, 2018

Thanks for all the help guys. Now I know what needs to be done.

Hobo,NC · Jan 18, 2018

3 phase power runs thur my property but I am not on that line

About all I get from it is a discount on my property tax..

I can make room I always find away to clear a spot for something new...
