I have an old dozer made by the Windolph Corp in Portland Oregon in the 50s.
Originally this unit had a Wisconsin TF (14 0r 16 HP) with a Crosley 3 speed transmission.
The Transmission had a 3.29 to 1 ratio in 1st, 1.72 to 1 in 2nd and 1 to 1 in 3rd.
The Wisconsin engine and transmission were removed and replaced with a Duetz F2L511 diesel engine and a hydraulic pump and a hydraulic motor.
The problem is that the dozer has a lot of torque and is very slow moving. So I have been reading and asking questions and pondering of what can I do to make this a little closer to speed selection and gear choices of what was there originally.
One thought is to install a hydrostatic transmission. I have done much looking on line, ebay and other places trying to figure out what would be best.
Since the original motor only produced 16 horse power at best, then the thought is that the Hydrostatic would not need to be that beefy.
So how does one determine what size and specs one needs for a hydrostatic transmission? Then where to find one that is somewhat economical. Not a lot of room between motor and rear housing assembly. So the smaller the better or maybe the shorter the better.
Thoughts? What would you do?
