Does anyone know of a supplier of used parts for Kubota excavators? I have managed to destroy one of the cylinders on a KX71.

Destroyed as in NOT possible to rebuild? Like it got bent? If that is the case, would/could you replace it with the same length and ID/OD? I have no idea what/where to find a cylinder, and I would be scared to see what Kubota sells ONE for.....$$$$$$ Which one is it, boom, stick or bucket?
No matter what failed take it to a good hydraulic shop and get a quote for repair. If anything is salvageable it will cost less to rebuild then buy new. We have a couple of shops in this area that rebuild ANYTHING hydraulic. One does all the maintenance for World's Of Fun, and they have some monster cylinders and they have to be built to a spec that protects them from a liability most don't.
There was a set screw securing the cylinder on the end of the rod. My mechanic didn't see it and ruined the threads on the end of the rods. The only way to get it off now is to cut it. That still leaves bogus threads. I might try that and some sort of thread chasing device. I thought about cutting the pin boss off of the end of the rod, rebuild the cylinder and re welding the boss. Fortunately, my Kubota dealer will sell me the entire cylinder for about $200.00 more than I was quoted for the repair. I would save that $200.00 but this being a popular rental machine, I would loose several times that amount in rental while waiting for the repair to be done. This machine rents on a nearly daily basis. If anyone has suggestions on how I can repair it myself, I would be happy to hear and try. It never hurts to have an extra on the shelf. Needless to say, I have instructed my people not to open a cylinder without me present. This is about a $1000.00 screwup.
Call your kubota dealer, get a printout of the parts breakdown for the cylinder and pick the parts you need. Should be able to replace the damaged stuff fo less than a new cylinder.
Its hard to find a generic cylinder that would work in its place. Unless you have a machinist in your back pocket.

What model is it?
I know the rental game, time is money, Your probably better off just buying a replacement and then getting the other repaired and shelved for later service.
The amount of money you will loose waiting for things to get done is not worth the time.
Unless your married to the local dealer, you might be able to pic up the cylinder from a Kubota parts wholesaler for cheaper.

I have a really good relationship with my dealer. I use them exclusively. If I buy a machine, I always buy Kubota (if Kubota makes the needed machine) from them. The machine in question is a KX-71-3. This has become a project and a challenge for me. Tell me where this notion fails. The cylinder set screw in question is at the very end of the rod. Having damaged the threads should only involve perhaps one inch of the threads. What I plan to do is have the cylinder machined off to the rod to see how much thread is left intact. If there appears to be enough, I will replace the cylinder and go from there. There should be plenty left in that the cylinder only moved 1/2 to 3/4 inch. Thoughts?
Unless I understand you wrong it sounds like you are talking about the damage was done to the cylinder barrel it'self. Can you buy just the barrel are fix the problem?
I said cylinder when I think I should have said piston. The damage is to the threads holding the piston on to the end of the rod. My guy could only unscrew the piston less than an inch. I think there is enough thread undamaged to receive a new piston.

Ok now that makes a ton of difference.
The design of those pistons is that the treads on the other side of the lock set screw is the actual holding point of the piston, if the treads of the piston are still good then you'll have no problem cleaning up the last threads and reinstalling the piston.
Just a note:
You will also notice that there is a gap in the treads like one is missing this is by design and that is where the set screw lands.
As it turned out, a new cylinder was $200.00 more than the total of parts need. Another lesson learned.
I repair a lot of different smaller equipment, I've found it is often cheaper in the long run to replace the part you're trying to salvage than the time and effort it takes to make the repair.
It may not seem like it up front, finding the parts, plus the cost of parts and the time involved in finding the right source for parts/repair and a work around to make it work. it all factors in.
especially with popular equipment, the down time alone is often enough to warrant the cost of new, yes it sucks, and it's a hit to bottom line, but if the machine isn't working, neither are you !
I just went thru similar with a customer last week, serviced his machine last month, told him he needed to replace the drive tires, they were coming apart, serviced machine again last Tuesday (400hrs since previous service), tires are coming apart, machine is hopping because tire core is shot ( solid tires ) again offered to order tires, not yet...... got frantic call Friday morning, I NEED TIRES NOW, we're DOWN ! None of tire companies had a press truck in the area Friday, ended up "renting " a set of tires off another lift for the weekend.
$1500 for a pair of tires doesn't sound so bad once the machine you depend on is sitting on the ground and you can't use it.... it will happen again next month
