Gresen 2702 loader valve: fix or replace?

[mennometis]

Spools not returning to center and leaking across front ports (left to right and vice versa.) Even when I hold the lever of the test spool centered, activating the other spool in both directions pressurizes the test spool. Happens when testing both front ports. No leakage across the rear ports.

Is it worth fixing?

Tractor is a MF 65.

I don't think you would have much luck repairing it. The spools are machined fit.

Send me a snail mail address and I will send you some Gresen service literature.

I realize Gresen makes quality products, but if the repair costs more than a $300 CAD replacement valve, I'll probably choose the latter.

The internal spools are fitted to the valve body bores, so they are not replaceable. If you can't make it work without bypassing the spool when you hold it in the center, I would say you might as well get a new valve and not waste your time or money on your old valve. JMHO

I put in a new BLB BM20 valve on my Massey 65 and there is no oil getting to the loader valve. It's dry. The 3ph works fine so I know the pump is working. Lots of air up there in the lines, but I would expect some oil to pass through it. I cracked the unused second T (tank) port plug on the loader valve and no oil. I'm thinking the TS300 selector valve on the lift cover has a major internal leak. Any other ideas?

I moved all lines one by one identical to the Gresen 2702, so I am confident in the routing. Top port on TS300 is pressure port correct?

By the way, if anyone is following this, the BLB BM20 spools are opposite direction than the 2702 Gresen. That info might save someone an oil spill from a swap.
Otherwise, the issues I was having was misunderstanding the 3pth controls. Human error and no damage done, thankfully.
