Update on Questions about front end loader on 660 ford

Here is my old post;
(I'm have a problem with the bucket loader on my 1958 Ford model 660. It lacks power and leaks down at a fast rate. The system does not leak on to the ground anywhere. I bought the tractor about 2 years ago and the hydraulics worked well then, other then it did leak down some. I really have not used it that much to wear things out. So I'm pretty sure the control valve is causing it to leak down, but I'm not sure if the lack of power is the pump not putting out enough pressure or the valve leaking it all out. Is there a way to test this? How hard and or expensive is it to rebuilt pumps and or control valves or is it cheaper to replace them?)

I just wanted to update this thread. First Thanx, to all that replied with your comments and help it finding the answer to this problem

I ended up just buying a new set of spool valves for the loader and it fixed all the problems. no more creep down and power like it has never had before. Cost me about 150 bucks off E-bay for the valve and I had to spend another $80 on getting some new lines made and adapters to make some of my old hoses fit the new valve. But it was well worth to have a tractor that works like it should again.

Herte is a picture of it with the loader working like it should.
