Fast dump and full curl not working correctly

[LD1]

I missed the part about having a diverter! Definitely would be high on the list. :thumbsup:

Ditto....especially if it's tied to the curl circuit.

Didn't Dawn on me because my mx has a Regen only valve so I linked my diverter with the lift/lower

Also try swapping the lift and curl qd's on the valve if the issue follows the loader and not the valve then it is from the qd's forward if the issue follows the valve then it is the valve. The only issue I could think of in the valve is a stuck load check valve. But my vote is definitely is the diverter valve can you easily take it out of the system with 2 unions?

Even a stuck load check would allow flow in one direction. CM is having an issue in both directions.

FIXED IT! YAHOO!

It was a QD for the diverter valve, hidden against the frame rail, behind the second QD for the diverter, and a sleeved run of two hoses returning from the diverter running to the torsion bar mounting for the QDs that run the grapple, plow, sickle bar, etc.

I was removing the 2nd QD, (of the 4 on the spool/valve which controls the joystick), when sitting on my creeper I saw the above mentioned hydraulic line(s) and at first thought the connector I was viewing located on the inboard side of the frame rail was a solid, NOT a QD connection. I began to wonder why there would be a connector at that location.
As I prodded the line I could readily see it seemed the line was solid, but upon further inspection the cable tied to the frame series of lines might not be as solid as they seemed to appear. I creepered under the frame rail and saw the inboard QD had evidence of being hit by a stick or branch, but was still closed. Digging further toward the outboard line, when I grabbed hold of it, it became apparent that the line was NOT connected to its QD! Eureka! There was the problem, and I might have missed it completely if I hadn't wondered why there were possible QDs in the location to begin with.

Turns out when I installed the diverter, a number of years ago, I must have installed the QDs to allow for relatively quick release of the diverter's hydraulic lines in case I decided to remove the loader from the tractor.
What is bizarre, beyond the uncanny way sticks find to disconnect QDs to begin with is it became clear the most inboard QD had been pushed back against the collar of the outer QD and caused the collar to release the more hidden from access QD!!:confused2:
You had to see it to believe it could happen this way?!

I had to make sure this NEVER happens again, so I cut some hose sleeve pieces I had for this type of situation, and I opened both pairs of QDs and sleeved each and cable tied the sleeve protection and the mass of lines on both sides of the frame rail, so hopefully a future stick would not be able to do a repeat performance. I had bundled and pushed all the same lines and QDs previously to prevent exactly this potential problem, and had thought about sleeving over the QDS, but thought that the likelihood of a stick finding its way there was near impossible, and probably would have had to go find the sleeving, which would have delayed wrap up and hidden them from view when looking for them in future to uncouple them. End result, no time saved on that thinking... I thought about placing a hose clamp around the area behind the collar of the female QDs, but wasn't sure I had any that would fit, so I went with plan A.

Everything is buttoned up and when I find time I may post pics I took to show how much of a demon seed this stick actually was!
I went out and plowed for hours until I got called to dinner! Also Yeah!:thumbsup:

Thanks to all for your insistence it was likely the QDs; just not the ones that usually get disconnected at the spool valve! Yikes, at least I can deal with the huge amount of unexpected snow.

Hope this helps someone with similar issues.

Way to go!!! I am glad you got it going again! :dance1:

Thanks again, all posters helped me be more diligent than I might otherwise have been. It speaks to troubleshooting rather than just replacing potentially suspect parts at huge expense, downtime and frustration!

Now on the same note about the exposed and very vulnerable loader spool valve and it's QDs. I may have a simple solution I have yet to implement, but have thought long and hard about. Here it is.
I believe a thin piece of Plexi could be slid in above and a similar piece below the QDs. Then a machine screw could be run through both pieces with a Nylock, or even a wingnut attached to sandwich the QDs enough to keep sticks, and short sapling stumps etc. from being able to reach the QD collars and prevent accidental QD disconnections that frustrate many, including me have experienced with the piss poor location of the valve/QDs.
Please Steal this idea, and use it freely, and if it works, or a modified version works share it here with pics of the design. Just mention me, send royalties to my address and collect the agreed to final deal commission!:thumbsup:
