Farmall M hydraulic advice

AndrewAnderson · Apr 22, 2017

I bought a Farmall M today at auction for 1100$. One owner. Decent rubber. Straight tin runs excellent. Has a single rear remote. I want to have a double acting cylinder on it. I have a valve that I could plumb my pressure line into and have dual double acting remotes. My question is this: where would I run my return line from the valve I have back to the transmission? Is this possible?

The return is best plumbed into the drain of the belly pump. It is done with a T facing so the hose goes
in sideways, and the plug is still facing down. This keeps the oil from splashing at the fill pipe (the
only other place it can be plumbed. The transmission is filled with 90 wt gear oil. The Liftall belly
pump is hydraulic oil, or 20wt non detergent in winter, 30 in summer. Hytran Hydraulic oil is fine. Jim

Thanks Jim! Seems simple enough!

The return line should go to the belly pump fill pipe. Belly pump is not part of the transmission.

I agree with "Rusty." Get a "Christmas Tree" and hook it to a T on the fill pipe. I have not had any issues plumbing it this way.

The other way (fill pipe) works, but return volume of fluid can make a mess through the vent in the cap,
and makes it harder to add hyd. oil when needed. The dip stick is also defeated when the return is
plumbed into the top. Jim
