Backhoe Kubota K650 Backhoe Attachment (grey market)

[J. C. Fielder]

I recently had 3 cylinders on the backhoe repaired, the first two worked fine and the hoe was digging ok. Repaired the swing cylinder and hose and suddenly no power. Could the relief valve be stuck open? How are these repaired. Do you have a schematic to repair these valves (there is one on each cylinder. Any suggestions would be helpful. Thanks

Are you running the K650 off the PTO? If so check to see if there is a pin through the shaft coupling of the pump to hold it onto the splined shaft to keep it form coming off the shaft. I have a K650 sitting up on the hill not, at the moment, mounted on a tractor. Where are you located?

 

[J. C. Fielder]

We are in Conroe, Texas. Yes it has the pin in it. Fluid is coming thru the pump. It won't raise the boom or swing. Have you had similar problems?
I can stand on the outriggers and they won't lift me.

No. I've never had it mounted. I was looking for a tractor to put it on when I bought the tractor a backhoe on it.
