Tilt hydraulic cylinders out of sync

[ovrszd]

Richard, would putting one of the plates (the most forward one) square up against an immovable object like a concrete wall, with the other sticking out in thin air and then operating in the dump position maybe "untwist" the tube? The dump position would have the most force from the cap end of the free cylinder. Just an idea, and would be easy to try. What do you think Richard?

It would be my first choice if trying to "twist" it back into place without cutting/welding. My only caution would be to refrain from pushing with the tractor. Only push with the hydraulics. Then you won't overload the system and risk damage.

I twisted mine when my bucket came unlatched as 4570 said.

I tried the method James suggested but my hydraulics weren't strong enough to "repair" it.

So I cut/welded. After cutting the tube I aligned it by latching on the bucket. Welded with bucket on to hold it straight and determine the correct width at the top.

Then I extended the lips on my bucket just to make me feel better.

I’ve bent 2 different ones like that but both times the levers came up. I need a hydraulic actuated quick attach.

I am guessing here, but I bet those little timing tubes are just made out of A36 (mild) hot rolled steel. Therefor they don't have much "spring" or return ability. Unlike a real torsion bar like in the old Chryslers or Dodges or even the torsion bars in a old Panzer, Tiger 1 that had torsion bar suspension. those bars would have been made out of a springier steel and tempered properly. These little bars on the tractors get their real strength from the back of the bucket. Not that you couldn't twist one if you did something real um... dumb. So bottom line, you twist one, it will pretty much stay twisted. It ain't gonna spring back by itself.

Keep in mind that you ironically have more dump force than curl force when more curl force would be more useful most of the time. The reason is of course its there are more square inches for the fluid to develop pressure against because there is no rod on the cap side of the cylinder (dump side) with the rod in there on the rod side (curl side) of the double acting cylinder there just isn't the surface area to push against.

Which is why most real loaders don’t hook the cylinder straight to the bucket and use a lever to curl the bucket up on the extension stroke.

Thanks for all the suggestions. I also found a post from 2016 with pictures showing what it looks like where one side of the QA is up against the stops on the front end loader and the other is not. One of the suggestions on that post was to put a metal shim on the side with a gap to change the position of the stop, then curl the bucket in a little at a time, remove the shim, and check the gaps. It took a few tries to figure it out, but I was able to use the hydraulics to remove the "twist / bend" from the tube to the point I can now get the bucket back on the QA plates. Alignment is real close to being the same and nothing is binding when installing either the bucket or forks.

Learned my lesson and will never try to push again without an implement on the front end loader!

Bending it back straight has been covered many times, here is one thread: https://www.tractorbynet.com/forums/mahindra-owning-operating/321315-quick-attach-bent.html


Edit: Too late, you already fixed it :thumbsup:.

Yep. That would be very cool.

Excellent!! Thank you very much for posting the results. Often we have threads started here describing a problem. Several posts are offered for fixing the problem. Then nothing. We greatly appreciate your time in coming back here with the fix. Someone in the future will search and find this thread and be able to fix their problem just like you searched and fixed yours.
