Damaged Hinge Pin on Stabilizer Leg - Kubota M59 TLB

[SidecarFlip]

I have to be careful with my valves, sometimes they don't go fully into the neutral position and the jack will drift down. I discovered that doing some loader work and something felt weird. I was dragging the jack in the lowered position.

Previous owner might have had the same problem, may have even driven into something with the jack down (my guess) or hooked the jack with the bucket.

Both are very likely. I remember back when I owned a Kubota backhoe my stabilizer legs also dropped. In fact I had to use tarp straps to keep them up...and it's quite possible to hook a pad with the bucket when digging.

Whizbang... from your pics .... it looks like the cylinder -end/boss is damaged by stretching and is likely weakened significantly. While in the extension mode that likely won’t cause too much future trouble, ... now is the time to replace it, IMO. You will not be able to restore it’s strength by beating it back down...in-fact, that action will further weaken it.
Sorry to say it, but if you undertake this repair, now is the time to do it right, and that means reshaping the ears, re-bushing, and replacing the cylinder.

Beating on ANY deformed steel part is NOT the way to repair it. Real simple Cold forming anything more than once will alter the crystaline structure and weaken it further.

You may be able to get the cylinder ear replaced at a cylinder repair shop. I am not sure if that is possible or cheaper but you may want to check

Guys, I didn't say do it cold. He's going to have heat there. And just to get it up and running. Ordering parts for the cylinder or a cylinder is going to take time. Especially a forged base eye.
You should run a straight edge on the cylinder rod to see if it was bent in the accident.
I hope that is grease or dirt on the front lower stabilizer frame and not a crack in the steel.

Update: Working towards getting a new cylinder tube/housing or good used cylinder on hand before I tear into this. I also ordered some material to have to potentially make a longer pin if necessary. I already have a new OEM pin and will have stock on hand if I have to make one.
