I've been through this a number of times with the early Workmaster series. Is this your first issue with this circuit?

A quick look at Amazon shows at least a dozen different units, many of which would suit your needs, all in the $100 to $150 range. Many with #8 and #10 O ring ports. You're running out of excuses.

You've tried the "jumper wire with 12V" and listened/felt for the click? You're testing the right one? The one on the top front of the pump, not the one on the side.

I don't really mean to be nosy, but why are you concerned about solenoids?

It IS an "off the shelf" item. You're simply over complicating it. Get away from Nimco numbers, look for something that fits, and go with it. People do this very thing every day. Personally I prefer components with O ring ports but that's not mandatory for anyone. We're guessing at this point...

That's about all one can do in regards to testing the coils. Anything else would be dictated by circumstances.

Good start. They do look like O ring ports with JIC adapters, but fittings can be deceiving. The second photo shows (probably) a power beyond sleeve and an adapter. Unless that's an elbow with a jam nut an SAE O ring fitting would not have a washer there. Three lines to the tractor indicates...

No

I'm not really sure, but I suspect it's a combination of things related to fuel traveling from the tank to the filter base. I never see it in newer tractors, only once they get some age on them. Is it build up inside the fittings, lines, ETC, something actually in the tank affecting fuel flow? I...

So do what I do in that situation. Snip the hose a few inches from each end. Put a screw, small bolt, or a piece of rod into each of the short ends to plug them off. Go back to work.

Does it have a hose from the top of the filter base going up to a tee in the return line from injectors to tank? if so, pinch that line off and try things again. See what difference that makes.

You're only working with seven GPM so pretty much any of the smaller units (10 GPM) will work for you. As for the "internals" a spool valve is a spool valve. Look for one with load checks, a float spool on one (if you think you need/want that) power beyond sleeve available, and (just my opinion...

It sounds excessive because it is. The Nimco valves found on many modern (and I use the term loosely) compact and utility type tractor loaders are some of the lowest overall quality products out there. There are gobs of replacement units out there that will work as well (or better) for as low as...

If your plumbing is indeed correct, then there must be a port or internal passage somewhere that needs to be plugged or blocked in order for power beyond to function. Any time open center valves are connected in series power beyond is a necessary function for proper operation. While I understand...

Good chance that without power beyond all the pressure is going to sump. Then again, not knowing where the oil comes from to this new valve, even that doesn't add up. The pressure line to the SCV. Where on the tractor does that come from?
