Unknown drive shaft

Postby AU52N » Thu Feb 21, 2019 1:03 am

In one of our purchases we obtained a bunch of H length drive shaft but along with them were a few others and I have able to ID most.  One in particular I can not.  It is 23.25 inches long from end to end, the crank end has 6 splines and the pinion end has 8 splines.  The main shaft is 0.561" diameter.  The area where a ball bearing and seal would be is 0.5965" and below that were a roller bearing would ride it is 0.6895".  I also found a pinion gear that fits.  Any thoughts on what the shaft is used for.  Pictures attached to help.
