Hurth Switch?

Hi I'm new to this and have a question.
I have a "Universal M25 with Hurth HBW50 (2:1) trans.rt I want to put a Hurth HBW503r ( 3:1)but the "spline" is an inch shorter than the HBW50
Any one know if there is an adaptor or a Fix for this?

Re: Hurth Switch?

Why do you want to change the tranny ratio? Not sure that's a good idea.

Re: Hurth Switch?

Good reason for the change... ZF bought Hurth long ago. Have you looked at the specs for the next larger one? zf10. It is a little longer box.
