What would cause this? Can it be fixed?

Tenn.FarmBoy, What ever the fault/problem is I/we sincerly hope for a positive/acceptable response from your dealer tomorrow. All 2,435,577 members and onlookers hear on TBN are monitoring his response!
Good Luck


Frank, now how did you know I will be talking to my dealer tomorrow?

You really know how to put the pressure on--2,435,577!!!!!

Of course, that may have just been your incredibly diplomatic way of telling me to quit whining!!!

Oh well, life goes on. What makes me nervous is not being able to identify what went wrong. When you back your truck into the tree, you instantly know, "I better remember that tree the next time. I need to pay more attention." This machine should be a tool that can be used to work--within reason and its capacities of course. It will be a tedious relationship if things continue the way they have been the first few days .

I'm wondering if the circuit to one of the curl cyliders is backwards. What do they do if you cycle them now? Does one retract while the other pushes out?

Hope its not that way. Otherwise, I'd say the attach failed on one side. Look at the scrape marks: something slipped.

Anyways, the way to untwist the QA frame is to deliberately reverse the curl cylinders and cycle the valve until they bend the torsion tube back into alignment.

Looking at the pic it looks like the right cylinder looking at the front of the tractor is not all of the way retracted. Did you try to fully extend the cylinders to the full dump position . Then retract them all of the way in and see what you have then. Thats if the cylinder isnt bent.

I did. It is impossible to fully extend them to the full dump position, and it is also impossible to retract them all of the way. The one on the left (looking at the front of the machine) will retract all of the way, but the other one stops with about 2 inches or so of cylinder arm showing. The twist in the cross bar is putting it in a bind and keeping it from fully retracting or extending IMHO.

Hey, Frank. I am just harassing you. I took your comments in the spirit they were given. As the old saying is, No need to cry over spilled milk. Thanks for the support.

Funny enough, my dealer is one that doesn't seem to know anything about TBN.

A possible scenario is that the nut came off the rod inside one of the curl cylinders, or the rod fractured where it necks down to capture the piston. I've seen that happen before, but it is rare indeed. The more likely cause is a QA handle not all the way engaged and the sudden drop was actually the grapple partially falling? Doesn't quite make sense though....

Steve,

The O-ring previously referred to was in the spool vavle for the third function. The cylinders have had no issues that I am aware of. As I stated prior, I don't believe a loss of hydraulic fluid was involved this time. Other than a very slight drip where one of the hoses screws into the third function valve, I couldn't find any evidence of fluid loss this time.

Farmboy,
Does the FEL still work properly? An 'o'ring may still have blew out in a lift cylinder but there would be no oil showing or lost as it's bypassing internally. Just a thought, hope your back up and running soon though.

Well, they came and hauled it away this afternoon. Based on my conversation with the service manager, it appears that all will be covered under warranty. My greatest concern is finding out WHY it happened so that we can address the cause and and avoid an encore performance. Unfortunately, we may never know the answer to that.
