Do I have a roto crank?

A quick learner from Boulder, CO says:
All indications are that my operator is a Roto, but almost all documentation I find on the internet shows a "hex" stud, or receptical. The stud coming out of my operator is definately splined and measured approximately .32" diameter with a dial caliper. Will this 39-336 fit do you think?

Thank you for posting on the Swisco Discussion Board.

I do believe the 39-336 will work. Roto did make a "hex" stud, but they also made a spline stud. I recommend you compare your dimensions to the 39-336 spline measurements.
