Ford 860 PTO shaft

[Novanut]

I'm trying to replace my worn PTO shaft with a new replacement shaft. I can get it inserted till about 1 inch left and then it stops. Feels like it's touching the PTO coupler because I can feel the splines as they line up and then move out of alignment as I turn the shaft. Both shafts are the same spline tooth and style and they are also both the same length. Any suggestions?
Thanks in advance.

The FORD 860 uses the PTO Shaft NCA-700-B (38), should be 32-11/16 LONG. Prior PTO N-Series Shaft is a tad shorter. Check the seal; sometimes it is installed backwards. Is gear in neutral?

Take the left side cover off (with the engagement lever) and help the coupler line up with the shaft.

After closer inspection, it looks like the splines are cut a little different. The old shaft has square cut splines and the new shaft has splines that are bevel cut /- which is making the bottom of the valleys shallower than the old one. Chalk up another one for the land of the almost right.
