Loader Valve / Curl function diagnosis

Well that thought went down the drain. Is the relief opening when you try the dump?

GPintheMitten · Sep 16, 2015

Yes. I hear a rattling sound immediately when the pressure is applied when trying to dump.

Then I would say the galley has to be blocked somehow.

I pulled both spools. I could see nothing wrong with then to the naked eye. Nothing scored, no junk. I put hem back in and attached the lines. Same bad behavior.

Waiting for my new used control.valve to arrive.

I received the used valve today. It was shipped by Marshall Machinery but I bought it from All States AG Parts. The box had a LOT of dirt in it. The valve body had dirt all over it. It looked like they dug it up out of a swamp. Someone attempted to put plastic caps in the ports but the caps were too large so they were bent in and didn't seal well. I hope the inside isn't too dirty.

In addition, the ports are not exactly in the same position but appear to be close. This was my whole reason buy and genuine Kubota part so that I wouldn't have to redo the hard line banjo fittings. I'm not real happy right now. But I may try and attach it tomorrow.

What would be a good way to attempt to flush the interior out?

No way I would put that thing on my hydraulics to try to save 20% vs the cost of a new exact fitting valve.

I vote send it back.

All States AG Parts sure has class. Over priced used parts and can't even take a air tank and blow it off before pulling off. If this works what are going to do with the old valve?

After some discussion, emails, pictures sent, I'm sending the product back and getting all my money back. All States AG Parts was actually good about it. The problem is that they didn't have the part themselves but they found the part at Marshall Machinery in Honesdale PA. Marshall shipped it directly to me. Marshall guy put it in an oversized box with a bunch of compost or dirt whatever in the bottom of the box. And the yellow plastic covers over the ports did not seal completely. I'm sure during shipping the dirt was thrown all over the valve.

Marshal won't pay for return shipping ($20) but All States Ag Parts will refund everything I paid them. All States Ag did offer to take it back, clean everything in their parts washer, paint it and ship it back to me, but I told him thank you but I want to just return it. So that's what I'm doing.

Next, I'll take my valve into the local Kubota parts dealer and have them match it exactly so all the hardlines will just bolt back up. If they can't guarantee that, Ill take JJ's suggestion and just get a universal valve for $200 to $250 and replumb as necessary.

The saga continues.

JJ or anyone else, I'm considering buying a universal loader valve with joystick from Surplus Center for approx $250 or so depending on which one.

I am looking at this one

2 SPOOL COMPACT 10 GPM JOYSTICK CONTROL VALVE

and at this one

2 SPOOL 10 GPM WALVOIL SDM102 JOYSTICK LOADER VALVE

Would either be better than the other?

The second one above (9-8583) specifically mentions it has load checks. The first one above (9-7401) does not mention load checks. Does it have load checks.

What is involve in cutting my current banjo fittings off, and converting to flared fittings to connect to the working ports that will obviously be in different orientation and position?

I think the actual size of either valve will fit in the same general location but I expect to have to do some steel work to mount it. And I expect to have work to do on the joystick itself. I can do those things but I've never worked with flared hard lines before.

Thanks.

The only difference I see, is the first valve has regen.

Both valves have load checks.

Regen provides a fast dump.

Just find the compression fittings for the line size, cut the line and adapt hoses and fittings to fit.

Pump flow will go to the IN port.

Install a PB adapter and run that line to the 3pt input line.

Tank line goes to tank/return line.

Set the FEL relief to the tractor specs.
