Both of the swing cylinders on my 580SL backhoe were leaking out at the rod.I got one of them apart and i am confused.The piston has a cast iron ring that does not fit tight in the ring grove.I can get a 0.67 feeler guage in between the ring and the grove.I do not think any one has ever been in the cylinder nor do i think the grove in the piston is worn.My new rebuild kit has a new cast iron ring that is the same thickness as the old one so it is not worn either.You would think it would fit tighter than this would'nt you?
