Last year I was lookiing for the same info you are. Here"s what I found for my MF-165 & for my 8N:

For the 8N I went w/ a Vickers"clone" vane pump offered by Attica Hydraulic. It has a 3/4" keyed shaft & puts out around 15gpm & 2000psi @ 2000rpm(if you want the exact model#, let me know & I"ll dig out the paperwork). You don"t have to have that much pump capacity for one of these loaders on the 8N, but I was thinking at the time I could use it on the 165(didn"t turn out that way). I chose this model after going thru all the Ford data I could find & talking w/ one of Attica"s pump engineer/inspectors.

For the 165 I found a used Denison vane pump on ebay. I took the chance because of the price & because vane pumps have replaceable cartridge & seal kits which are a fraction of the new pump cost. This one had a reversible cartridge, so rotation was not a problem. It has worked very well for me. It has a 7/8" splined shaft & is spec"d to put out 20gpm & 2500psi @ 1800rpm(as above I can dig up the model# if you want it).

I believe most industrial equipment today uses gear pumps, but I don"t think they tolerate trash in the oil as well as vane pumps do. They (industrials)have filters on both sides of the pump, I could only make room for a filter on the return side, so whatever comes out of my reservior goes thru the pump before it"s filtered.

My system capacity is about 5 gallons.

Depending on your tractor model & loader model, you"ll need a drilled/tapped crank pulley, hub, proper length drive shaft matched to the hub, & possibly a morflex coupler matched to the pump shaft & the drive shaft.
