Hydro on 4040/Pow'r Max

[Guest]

I hope I'm not opening a can of worms, but does anyone know who manufactured the hydro unit on the 4040 tractor? I'm not having any trouble with mine at present, but while doing some other work on the tractor, the thought ran through my head that I just may have to rework the unit someday. At present I suspect that it is a Vickers, but not sure. Any ideas, knowledge, tips, advice?

Thanks guys!

It's a Sundstrand Model 15 Inline which was used on 4040, 4041, 9020, 616, 620 and 720 Series Tractors.
That's all I know... :)
