Locating the Power Beyond

coachorr · Apr 11, 2025

I have purchased a 2 spool valve off Ebay for use in my New Holland TT75A for the bucket as I cannot seem to find the problem with my existing valve. There is little power to lift the bucket, however, the curl works fine. I swapped the hoses to see if it would lift the bucket, same thing. I'm thinking perhaps it's a collapsed hose? Any ideas or thoughts would be greatly appreciated. The pump is good as the 3 point hitch works fine.
My new valve has 2 plugs on the top, I'm hoping one is the power beyond but don't know which one. One is close to the pump/intake/pressure port; would that be it? I've attached an image of the valve.

Hard to say from the picture, but I think that is just an alternate inlet port.

As far as the loader goes, if switching the hoses resulted in the loader lift doing the same thing, then the lift cylinders are your problem, not your valve.

I would suspect leaking lift cylinder seals being the problem vs the valve since it didn’t work when you swapped hoses to curl.

On the valve question typically power beyond is at the opposite end from inlet and require a special sleeve fitting or plug be installed for power beyond function to be activate. Do you have any other information on that valve?
