Getting discouraged / need help Farmalldan et al

I ordered a greshen valve thru Force America and have spent the last couple of days trying to get it installed. After several trips to town getting hoses made I finally got it hooked up this p.m.. Problem is I still have no p.s.

Previously the p.s. would work only if I pulled both the flow control( 2-way) and Lift-all levers back. Now when I pull out Lift-all rod the engine pulls down and 3/4" pressure hose from pump vibrates. p.s. starts to work then locks.

Here is how I have it plumbed in: 1. pressure side of pump (3/4" hose) teed into P. port on priority valve (pv) and on to Lift- all 2. CF (constant flow) port on pv to 3/8" port on power steering unit. 3. 1/2" port on steering unit to tee in 1" return (bottom) hose from Lift-all. This hose then returns to fitting under flow control, then to hyd. filter and then to pump. 4. EF (excess flow) port on p.v. to flow contoll 5. T (tank) port on p.v. also tees into 1" return ahead of fitting under flow control.

I looked at a friends SMTA and he had used the same valve. Everything was hooked the same except he had mounted the p.v. valve at the side of the Liftall as where as I mounted at the back of the engine under the gas tank. Also he did not have a hyd. filter. I figured while I had everything apart and had to have new hoses made it would be a good time to install one.

Do I have something plumbed wrong, or could it be the filter is causing the problem? As I said in my post heading " I'm beginning to get discouraged. It's not as if I have no mechanical knowledge. My son and I farm 2,100 acres and due what mechanical work we can, but this one has us both stumped.

To top it off, one of the rear axle seals is leaking so I decided to fix that before coming in for supper. Had the wheel almost off the axle when I discovered that it was full of fluid. Sure glad I didn't get it clear off first. Don't know if the cherry picker would have handled it. In the a.m. will call the tire man and have them pumped out.

Mom said there would be days like this. She just didn't tell me there would be so many.

Appreciate all the advice I can get

Let me run this by you to make sure I'm following you.

Run the pressure hose from pump into the pressure port on the priority valve. From Excess flow port take that line to Lift-all. The Flow-control ( 2-way) valve will also feed off of the excess flow line. Think that's what you are saying.

As for friends SMTA, yes it has the Flow control valve. As to how his is plumbed; He disconnected 2-way valve from pressure line and ran straight back to Lift-all. Installed priority valve in a tee right in front of 90* el going into Lift-all. Ran excess flow line back to 2-way. Constant flow line to 3/8" port on steering unit. Hose from 1/2" port on steering unit and hose from "T" port on priority valve were teed into the 1" port exiting Lift- all.

Power ports are plug off, no cylinders. As for Lift-all working. Presently I have no need for it. Main thing I am interested in is to get the power steering working and also have occassional use for the Flow-contol. This tractor is mainly used to run an auger and occassionaly move equipment in and out of sheds. Also, it is my first attempt at restoring a tractor, though at this time I have no intentions of showing it.

Thanks for the reply,

Don't get me wrong, I'm not about to give up. Instead of discouraged I really should have use p-off.

I know the power steering unit works because as I stated I had it working before I put the priority flow control valve in. The only problem was I had to pull both hyd. levers back. Also, I am hooked the same, except now have added the priority valve.

I spent almost 2 years trying to find a bad electrical connection on our 4020 after 3 deere mechanics said they had it fixed. Finally found that ao they shouldn't be as bad.

It's just that some days everything seems to go wrong.
