I'm helping out a retired neighbor who recently bought a mid 70's Ford 3000. It's had a loader installed on it by cutting the pressure line on the right side coming from the pump and tying in the loader control valve. The problem is the loader is extremely slow. After starting it up, it takes 1-2 minutes before the loader will move at all. I tore into the rear and checked the filters. They were in good shape. Next, I rebuilt the pump including all new o-rings and seals. I found that the pump drive shaft had some wear on it where the seal rides behind the bearing so I offset the new seal about 1/8" to make sure it has a smooth surface. Still seems to have the same problem, though. I don't have a lot of hydraulic test equipment, but when priming the pump, I loosened the fitting going to the loader control valve and I seem to have good flow. Based on the fact that it takes so long to start working after starting up, I'm thinking I have a problem in the suction line, possibly sucking air someplace. I'm at a loss where it would be, though, since I've replaced all the seals around the pump and don't see any evidence of leaks in the line.
Has anyone ever solved a problem like this? Any ideas would be greatly appreciated.
