Test SOS .

[James Trovillion]

I bought tractor split at transmission, engine. Is there a way to test the trans without putting the tractor back together. I never saw it run, 881 Gold Demonstrator, with Ford replacement trans.

I think I remember hearing that someone out there built them self a S-O-S test bench setup for doing just what you're asking. I'm not sure if it was John Smith or someone else. Hopefully someone will chime in that has a better memory than I, or maybe even the person that built it wil give you enough details that you could build your own.

All you would need is to rig something up to spin the input shaft, and then move the gear selector valve through its range and see if the output shaft turns at different speeds in the various gears. You would have to fill it with fluid first and figure out how to provide enough power to the input shaft to run the internal pump and still provide enough power that it would make all of he gears spin through to the output shaft and somehow monitor the speed of the output shaft.

Tony Jacobs is a SOS expert . I know I've seen him on here before . If you could somehow locate his contact info , maybe he could steer you or help somehow . God bless, Ken
