Pop in FEL Curl Cylinder in my BX25D - Bucket uncurls on own weight

analog · Sep 2, 2017

I was using my tractor's FEL today and I heard a loud pop up by the FEL while having the bucket about half way curled against the ground pulling backward. Immediately afterward, I can curl the bucket all the way but it starts uncurling without any weight in it, it will uncurl within probably 30 seconds. Curling it back up occasionally makes another popping sound in the cylinder, so there seems to be something broken in there. I can hold weight with it as long as I keep the bucket curled, although I haven't tested it with any large amount of weight.

Any suggestions? How hard is it to service yourself?

Thanks for any advice in advance.

Sounds like the piston came off of the rod inside the cylinder, if your lucky it's just the nut that came loose, but I'd be the threads are stripped clean.

Repair is not to difficult, but the part(s) may be expensive.

Oh, and welcome to OTT.

I would be more inclined to think it rolled a seal or broke the lands on the piston for the seal, because if the nut cam off the rod it would just flop forward, and it wouldn't be drifting.

Quit using it, because if it did break the lands on the piston it will scar up the cylinder and make it worthless.

That's kind of what I think maybe a seal popped off. I did stop using it and won't use it until I get it repaired.
