[Kjetil]

Hi

Anyone know the purpose of the Nuday 5521 tool.
One side is approx. 1 1/2" diameter (19 teeth), the other side is 2" (29 teet.
It also have 1/2" drive in the center of the tool.
Any help welcome.

Looks more like a splined shaft adapter.

Since it has the Nuday number, I would assume it is a tool of some kind

Looks like it is made for turning either of two different splined shafts. The transmission output shafts and pinion gear shafts of the 1955-1964 hundred, '01 and 2000/4000 series 4 cylinder Fords come to mind since they changed from coarse splines to fine splines sometime around the time of the '01 series.

I think that he knows that it's a tool. Here is the first sentence from the original post where he called it a tool:
