I called Northern Tool. They do not have a pump
listing by application....i.e. 1951 Farmall M. They
told me to call back with bolt pattern, GPM flow,
open or closed and something else I cannot remember.
Do you know how I can obtain this type
info,,,,thanks again and standing by
You will probably want a pump in the 1.8 to 2.2 cubic inch per revolution to get the flow you need (2.0x 1500 / 231 = 13 gpm), assuming your M turns about 15-1600 rpm.... but I don't know for sure what an M is at full throttle. Using a loader, you will no doubt operate at less throttle much of the time, so going toward the bigger size will help. I am assuming your loader has it's own valves? If it does, it is most likely to be open center, meaning the flow will just by-pass with no load on the pump when the valves are centered.
As for the bolt pattern, you will need to measure that on the front pump mount you mentioned you have. I have the common dimensions somewhere in my information, but it's been so long I have no idea where it is. In Cessna/Eaton pumps (where I worked for 38 years) a larger B series or smaller L series will fit the bill, but I forget the mounting size... been retired 10 years the end of this month and really didn't deal with that part of the job for about another 12 years, so 22 years, I've slept a lot since then.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let�s make one more addition to our series on hydraulics. I�ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
