Which cylinder is not providing hydraulic pressure

When you say not working does that mean that the bucket tilt settles or does not hold possition as if one cylinder has the internal piston leaking and is letting oil bypass. An easy test is to chain the bucket so it can only tilt halfway and try to tilt it against the bypass. Unless it is a catastrophic leak the barrel will get warm quickly in the center where the piston is letting leaking hyd fluid past.

Thank you for the reply, and yes you are correct to say that it does not hold postion( slowly tilts forward when bucket is full), although it does move it's full range of rotation.
So let me get this straight. I should chain the bucket so as to tilt only halfway and apply downward pressure with the control level and get a helper to feel the barrel for warmth. What about the one that is normal, what happens to it, will there be a possibility of blowing the outer seal.

You may have to isolate the cylinders by capping the ports and lines off to be completely sure if it is the left cylinder or the right, or even if it's the valve that's leaking. We recently went through this same process on a skid loader. Repacked a cylinder and still or soon had the problem with it leaking down again, so repacked the other one and that didn't fix it. Then capped the ports of one cylinder and the lines to it and discovered it was leaking by the piston seal. When we opened it up again, we discovered the opening to the port was sharp edged and when the piston with the new seal was slid by the port, it cut the lip of the new seal. A few strokes with a dremel tool and a new seal fixed that.

Whatever you do, stay safe!

The easiest way to check has already been covered, work he lever both ways for a bit and the one that gets warmest is the one with the leak.

Gentlemen,

Thank you for the replys, I will try your solutions as soon as I can, work has been busy, so I can't give that up. Got to pay for my hobby somehow.


Thanks again,
