Are automotive spline different than ANSI splines?

Are automotive spline different than ANSI splines?

Are automotive spline different than ANSI splines?

(OP)
I require info on this subject as I am going to cut a 32 tooth male spline to match the mate which is a output shaft on a GM turbo 400 transmission.
I was told by other sources that the automotive splines are dis-simular to the standard. Anyone?

RE: Are automotive spline different than ANSI splines?


sageman:
It depends. They can be standard (ANSI inch, ANSI metric, DIN, ISO) or - very often - designed specifically for the application. And both mating splines - internal and external are allways designed at the same time. Try to find the spline cutting data for the output shaft, then your spline can be relatively easy calculated. In the worst case you can measure the critical data on the known spline (major, minor dia; pressure angle, tooth thickness(size over/between pins)) and design the mating spline.

Sageman, I also havent the foggiest if GM used SAE splines, but this place will! http://www.moserengineering.com/moser_interior/technicalassist.htm
Call and ask Greg, he has forgotten more about Automotive splines than most of us will ever know.

P.S. I do know at least in the aftermarket various configurations are used, I.E. Mark Williams 35 spline axles use different splines than Strange, etc...

Thanks all!
I did make some measurements on the male and found them close (measuring worn shaft)to the ANSI (inch) 32 tooth 24/48 30 P.A. spline and then Andy @ Moser confirmed the findings as well.
Good forum, keep it up!

RE: Are automotive spline different than ANSI splines?

Does anyone know where in the UK I can buy spline measurement pins??
