I'm in the process of putting a new 2 spool valve for the loader on my M. The problem I'm having is I took the old valves and hoses off and I'm not sure how to run the new hoses. The tractor has a pump ahead of the distributor. Do I just run the hoses from the 2 fittings on that pump or do I have to connect to the belly pump somehow? I don't remember just how the old one was hooked up, been awhile since I took everything off and probably a case of old age memory. Thanks for any advice I can get.

Unless some other real genius comes along I am not
sure we are going to be able to help you without
seeing some pictures of what you have to work with.
Do you have what you took off a picture of that would
also be helpful. The problem is there are so many
variations to how these systems were added to the
tractor. The most important thing is to know if you
have a max pressure relief in the system and that it is
set for about 1250 psi otherwise you can damage the
drive gear for the cam. Let us know how you are
posting and what capability you have to get some
photos up on here. We can work through the steps of
posting pictures.

The answer to your question is no. If you hook the two lines from the pump directly to the valve, where is the oil going to come from?
You need a reservoir for oil. Most likely the old setup used the belly pump as a reservoir.
Typically, you would connect the bottom drain of the belly pump to the suction line on the distributor pump. From the pressure line on the distributor pump to the IN on the valve body. From the OUT on the valve body to the fill tube on top of the belly pump.
That's the simplest way to do it. Make sure your valve body has a relief valve in it and it is set to 1500PSI, or you may regret this whole project when your cam gear gets stripped.
Depending on your loader the 6 quart capacity of the belly pump may not be a large enough reservoir. 3-5 gallons would be much better to keep the system from running dry and for cooling of the oil.
