I was asked to post info on an aux-trans setup I built and installed. I did several, all the same. All around 30 years ago before I had a digital camera. So photos not great. The crawler I did for my self I am still using as a trail-machine in the Michigan UP. 30 years and it's worked flawlessly (as far as the trans goes). Hard to imagine using it without the aux trans. I was involved with several people also trying to do it with various differences. For me, I wanted a stock Ford Model A trans to work with no mods to it. The original optional aux that Oliver offered, made by Trasco, modified the Ford Model A trans with a special input shaft and retained the original Oliver clutch-disk. I did not. Mine uses a stock Ford Model A trans and a repro Ford Model A disk that is cheap and the same diameter as the Oliver-Cletrac disk. I did add sealed input and output bearings since the original Ford design has no oil-sealing. Here are some photos ands specs. Also a few photos of the original setup from Oliver.
