Riverside auxiliary transmission

Post by Jim-B » Wed Aug 20, 2025 6:34 pm

Hi all, I have this Riverside three speed transmission with a reverse. It looks to be the same as a Muncie ? Anyway I am missing the
Cupping with a square hole that goes in the back to couple the drive shaft. Would anyone happen to know how long that cupping is?
I would like to make a new one. Thanks for any help. Jim

Hi Jim,
If it is that same as a Muncie it would be 2 5/8" long. I make the Muncie ones out of a Spicer 7/8" square PTO slip yoke. The number escapes me
but is in a older post on Muncie couplings.
Craig.

Craig, thanks for the reply. I have the yoke you mentioned. I just needed the length. Thanks again. Jim
