Are the lift arms on an 8N interchangeable left to right and vice versa

Considering that the arms are in a sense keyed by a difference in the splines, I would say no they are not.
Since you would have to flip one over to get into the correct position, the splines will not fit on the shaft on the other side.
As I said, they are keyed so the will only go on the shafts in one position. No worrying about getting one higher or lower than the other one.

You are right I should have looked at them before I asked the question they have whats called a "blind spline" so they will only go on in one direction
"blind spline" Thanks, I knew how it worked, just couldn't think of the proper name. :wink:
The thing is though, I looked in the "N" parts book and it shows part number 543. It shows "two required". I would think they would have different part numbers, one for each side.
Are the blind splines on the shaft different on each side? I've never removed the lift arms myself but I remember being told on here that they only go on the shaft in the correct orientation.
Unless a man wants to keep his tractor original the later model lift arms are much stronger . I have replaced a few of the light duty broken and twisted 9N/8N arms with used arms I have bought on Ebay , usually $20 - $25 a set if you wait for a deal .
The early arms work left or right , the later arms have a slight angle on the end and are right and left , not that it would really matter if you installed them backwards .
This is not a cheap arm , but it shows what to look for .

Better pics , 3rd pic shows the angle at the end and shows the key way is inline with the direction the arm is pointing .
