Sparky2 said: (quoted from post at 12:26:50 11/10/12) Thanks, yes I like the live hydraulics on the 300.

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.
