pto sleeve stuck

[kenbob]

My old Case rotary cutter has been making me a lot of money lately so trying to show it some love. SInce I have had it. The sleeve that is around the pto shaft is stuck together. The nylon bearing in back is gone. I got the bearing, and hope to get the sleeve unstuck so it extends with the pto, instead of being unsupported at the back and flopping around a bit. I have tried heating the outside sleeve and spraying penetrating oil at both ends of the sleeve. Nothing moving so far. Wondering if there are any tips from the wide collection of great thinkers out there.

I f it were mine I would take my angle grinder with a thin blade and cut it up to the inside tube. Heat the tube and put more penetrating oil in the cut heat it if necessary, use a hammer but dont dent the tube. Maybe make a cut on the other side if necessary. As a last thing, pry the tube apart at the cut, the weld it back together, at the ends only where you can file down the weld on the inside so it can still slip over the other tube. Stan

Thanks, Hoping I don't have to almost have to destroy it to save it, but it might come to that.

Did you get it out of round or have a slight ding or dent in the tube? That might require a bit of surgery to get apart.

If it's just rusted, bang on it with a rubber mallet or similar. Just enough to let it know you're there. The iron in that was stamped out once already, so no need to get excited. Then whatever penetrating oil you prefer or kerosene, etc. If you have a bucket of drain oil handy, pull the shafts & set the tubes in there & let the oil soak. Then, use whatever method you want to pull them apart without distorting the tubes. Couple tow straps, a tractor & a tree might work. Just watch that the tube section doesn't come flying up at you when they pull apart.

Indeed. I pull things like that apart with the forklift, or loader.

I have an old steel PTO shaft cover that got dented. Removed it from the PTO shaft, chained one end to a tree, the other to the tractor drawbar. Result was, it came apart, but the dent in the outer sleeve made a long dent from the original to the end of the inner sleeve. It is now useable after straightening the outer sleeve though.

Thanks for the good tips

If the sleeve is not completely closed up, you may gain some ground pushing the halves closer together to get some movement.

Also a good idea. I have an inch or so

I wouldn't spend to much time on it. Can't you get the new plastic ones from TSC for $50?

I never thought about putting a whole new shaft on it. I just got done replaceing a ujoint. Cost plenty, and the whole new assembly is only 129 bucks from tractor supply! I shudda looked at that first!
