Question on auxiliary hydraulics.

[Jason S.]

ok...you probably seen me post before about the auxiliary pump set up had been removed from my 175. I've managed to find most of the stuff to put it back in the tractor but here is my question. Most of the pumps I find are the dual section pump where its one section of the pump for the multi power or IPTO and the other for the auxiliaries. Can I use one of those pumps in mine which does not have multi power or IPTO but does have factory auxiliaries? If I can how would you plumb it in? Im asking because my dealer said most yes most of the auxiliary set ups can be swapped in but if all you can find is the dual section set up....then what do you do? Thanks for your help I really appreciate it.

Why don't you remove the rear cover from the pump, and slide the gear set out. Also remove the thrust plate but leave the outer "o" ring in place. Refit the cover and now you have a single element (Hi-output) pump.

Thats kind of where I was confused.I didnt know if you removed the gears if it would still send oil to that part of the pump, which I guess worse case scenario it would just go on thru and back out in to the housing...I have looked and looked at Agcopartsbook.com at the exploded views and for an 8 speed with no multi power or IPTO they show that dual section pump.I didnt know if originally it was blocked off or just flowed thru or what they done.

From looking at an old pump I have here, I would expect the area inside the pump where these gears originally were, would just become part of the oil pickup on the suction side of the "hi-flow" pump. I would blank off the outlet port on the low flow side as well, and keep the rear "o" ring in place, so the suction side remains "sealed", ensuring that there is no possibility of it "pulling" air.
Hope this helps,
Evan.
