W-6 Hydraliic's,

how do you put the routing system on a hydralic W-6 and have it circulate.
I have the hose's and the pump redone.but where do you put the other hoses so it'll circulate and not blow the seals out like before?

i used a short hose and plugged it into both the rear implement outlets to make a loop.

Assuming it is a live pump on the distributor drive (or front of bolster direct driven). The pump is used on an open center hydraulic circuit. This means the valve must be an open center valve. The pressure from the pump goes to the illet to the valve. The exhaust from the valve goes to the reservoir. The reservoir is attached to the suction side of the pump. This allows the fluid to operate in a circle including the reservoir. When the valve is moved (single acting) the fluid is directed to the cylinder moving the piston. When the valve is returned to center, the oil is held in the cylinder, keeping it extended, and the open center is still flowing oil to the reservoir as before. when the valve is moved to lower, the pump fluid still flows through to the reservoir, and the fluid from the cylinder is now allowed to also return oil to the reservoir, lowering the cylinder.
In a double acting valve, the fluid flows just as above with the valve in the middle. WHen moved to lift position, the iol is directed to the bottom end of the cylinder. At the same time the retract end of the cylinder is allowed to bleed oil into the reservoir.
When the lever is returned to center, the oil in the cylinder is held in the cylinder (both sides of the piston) and fluid travels through the center to the reservoir as above.
When the lever is put in the lower position, the oil is directed to the retract side of the cylinder, and the extend side is blead into the reservoir.
I hope this helps. Jim

The valve should have a pressure relief control set to no more than 1200 PSI with the IH distributor pump. Jim

Hi jim, Yea it does but now I gotta have a picture of how it all goes together after the pump.
have to get a control lever for fender too.
thanks alot jim for getting back to me on this.

Google should get you the routing of the hoses. They go from the distributer, down and under the fuel tank, then back to the left side floor. (IIRC they are the same basic setup as a W-9. I know the res is different so I can't say too much about that)

The diagram shows multiple double acting valves. it is the same if only one valve is used. A single acting valve is also shown it also can be used alone. The key is the connection through all valving back to the reservoir. Jim

So there is no pressure relief valve in the actual hydraulic system?

W-6 did not have a hydraulic system from the factory, so whatever this is, is pieced together.

So no, it won't have a pressure relief valve unless the person who set it up installed it.

It should be pretty simple.

1. From the pump's pressure output, you connect to the IN port on the OPEN CENTER valve.
2. From the valve's OUT port, you connect to a port near the top of the hydraulic reservoir.
3. From the bottom of the hydraulic reservoir, you connect to the pump's suction input.

With an OPEN CENTER valve, this system will just circulate the fluid until someone pulls the lever.

The OPEN CENTER valve you use should have a pressure relief valve built in to prevent blowing out the seals in the pump. However, it needs to be set properly or else it's as good as no relief valve at all. From the factory they come set for modern high-pressure hydraulic systems. Read the manual that comes with the valve to learn how to set the pressure relief.

A separate pressure relief valve can be installed in between the pump's pressure output and the IN port on the valve as well. The outlet from this valve gets connected to the reservoir.

I still insist it is a tandem center system unless it is a float valve...but I don't really care that much...

What I really care about is this....
So where was the pressure relief on a stock SM/SMTA live hydraulic system?

The single-acting valve inside the hydraulic reservoir under the fuel tank has a relief valve.
