trying to add a Behlen 201 dist flange pump and 201 torque motor to my M . Last fall bought this Behlen unit and now trying to add it to my Farmall M with a wide front and it has a loader. I added a resivoir tank and did not use a priority / relief valve as I mounted a test gauge to the input of the torque motor and monitored it and I read that this Behlen power assits pump has its own relief in the pump. . When I started it up it seemed like it was not getting enough pressure so tried to run it back and forth but was skipping like its low on fluid or volume . Even at 1/2 throttle it was still not getting more than 750 on the gauge .At neutral position it , it just goes straight thru the gear box and when I start turnimg the wheel right or left the most I can get is 750 . So I read that it takes at least 1,000 lbs to make this unit work. So I removed the model 201 pump that mounts on distributor flange . This pump has top mounted ports. The inlet/ supply is a 1/2 inch and the pressure out is 3/8 inch . So I looked it over and when I look in the pressure port it looks likie it is almost blocked with what must be the relief but it covers almost the whole port? Dont know how in the world the flow gets thru there but maybe the spring and ball is old and weak and letting it recycle spme and not letting the gear box get enough flow? Has anyone ever had a 201 pump apart? There is a welch plug on the side of the housing to remove the relief valve. and when it goes thru the pressure port and takes up 90% of the port and then extends thru to the supply port for the dump. I can't see how they can restrict 90% of the pressure port and expect to get and flow? Yea more pressue but wheres the volume to run the gear box?..So maybe the spring is weak and dumping some back in and thats why I have only 750 lbs.

I took one pump apart this afternoon, It's a gear pump and yes that is a relief valve that you are looking at in the ports. On the pressure port there is room under the relief valve for pressure oil to flow. When I had the pump apart I took the pieces to the parts washer for a good cleaning. I was able to get a fair amount of fluid around the relief valve. This pump is designed to produce about 3 gpm when running a rated engine speed.

I have a couple of those Behlen pumps. One feels funny when I turn it by hand, I'm thinking that I going to take it apart to see what it looks like inside. I'll post some pictures when I do. I'm hoping to have a look tomorrow. Charlie U

Thanks for the information and photo charlie. My picture is from the top down and yours if from the end cap off so I have not seen that hole in the relief .When I look at yours it appears to have a hole thru the relief ? or is that just a reflection ?...In .Mine I can't see a hole in from the top down. Also did you say that you think your relief spring is weak causing leakage?
