  • axle pin diameter 9n-2n
  • can someone give me the axle pin diameter where the pin goes through the brass bushing in the axle? I need to weld and turn down a worn axle pin.this is for a 9n-2n.thanks,chris

  • The pin you are looking for is around 2" longer then the newer 8n pins that are at a reasonable price. You have the cast mount, thicker, heavier. If you can weld, easy to make. When i replaced mine I found it a bunch cheaper to make one than a new one that would fit. Later I did discover there was a newer model that used the same pin but don't recall what model it was on.

  • Diameter is 1.749/1.750. If it were me I would buy a new one rather than spend the time required to build up and turn down an old one.

  • The drawing for the 9N-3126-B pin says the tube diameter is 1.747/1.748 and that the hole in the axle support is 1.749/1.750 . Does anyone know what the 2N pin number is/was?

  • I stand corrected. I believe the part number for the 2N pin is 2N-3126-E. Should be the same diameter and usable length as 9N-3126-B but with the addition of the 8N style retaining flange on the front.

  • Hmmm.. don't have that one. Wonder if it was later obsoleted and replaced with an eight digit number. Don't have the access I used to have.

  • I guess I didn't tell the whole story. I am working on a warhorse pin.as you know they are quite hard to find.i found a really worn out one.i assumed it is cast steel.but for some reason it just didn't want to weld well.so we turned it down and are going to shrink a sleeve over the pin.what do you think of that idea? chris

  • The OD of the axle pin is not a close tolerance issue. Sleeving it seems like a good solution.

  • oldhokie,thanks for your thoughts on the sleeve idea.i can't take credit for the idea.one of the guys in the shop thought of it when welding seem to fail.now, for the big admission,i am putting a warhorse mag set up on my 1939 tractor.after doing a warhorse,i really like this type of ignition set up.like myself, it's simple!please,purists don't ostracize me for this act of blasphemy.again,i just like simple.no battery,no starter,no wires,no problems! chris

  • Just make sure you don't thin the wall on that pin too much when adding the sleeve - not sure what the wall thickness is to start out.
