I have a 1-ton Cushman Truckster (the dump truck model) that's equipped with an underdrive unit attached to the differential. I'm going to remove this unit before selling the truck chassis, and I'm thinking of flipping it end-for-end and making an overdrive for my BW35 automatic transmission.

The Cushman uses a Studebaker 3-speed manual transmission, and the whole drive train is overbuilt to stand up to industrial abuse.

I'd have to adapt the underdrive brackets to fit the Spicer 27 differential, and the driveshaft would need to be shortened, but this might make an interesting project.

NO, I don't know what the underdrive gear ratio is. Probably in the neighborhood of 2:1. I'll have to jack up the truck and turn the driveshaft and count the revolutions to figure out if this would even come close to working. A 1:2 overdrive would obviously be out of the question, even with my 4.11:1 rear end. That would change the rear ratio to 2.055:1, and I just don't have the power to go that high.

Thoughts?

Steve
