610 bobcat

The tilt on the buckets leaks down , even without a load. Any ideas?

I would guess you need to replace cylinder seals.

Are there any leaks at the actual cylinder? I would think (guess) that with no leaks (I assume) at the cylinder its a valve that is the problem.

If the piston seals are bad, which is most common, the oil can pass internally from one side of the piston to the other. but it would make quite a difference in how strong the tilt is also.

I've had several leak internally with no sign of problems externally. On the 610, I always start with the cylinders (and pray that's the problem) simply because the valves are a major bugger to get to. Maybe someone has a better method of diagnosing the problem.....we'll both learn something.

unhook one line off of the cyl. plug the line. hook a hose to the port on the cyl and put in a bucket. start machine and work the valve. if oil comes out the hose the packing is bad. (after it is a the end of the stroke)

I don't see any leaks on the outside. I am trying to figure out whether its the cylinder on the bucket or the the control valve under neath the floorboard that is letting the fluid bypass. I am assuming that the control valve have o rings on the valve spools that could wear or tear that could let the oil get by.

Thank you mrdeere.
