Loader Need help with loader bleeding down.

[comfun1]

I bave a B7100 with a kubota loader and the bucket slowly dumps on its own. There are no external oil leaks. How can I determine where the problem is?

lift bucket up a foot in air, disconnect the quick disconnect if you have them. Be sure you are safe and stay away from moving parts. If it doesnt move, then you know the seals are most likely good in the FEL cylinders. The problem would be int he valves. If it still moves without hoses connected, then you mave have leaking ring seals.

All FEL's leak down, what's the rate? If it's slow don't worry about it.

It's getting faster all the time. It dumps now in about 10-15 seconds. A couple years ago it was several minutes. The arms don't bleed down or if they do it's so slow I don't notice.

If you're losing power then get the leaky cylinder rebuilt. The bad cylinder is the one that controls the function that is changing fast.

OP didnt say anything about losing power. Nor he didnt say what troubleshooting he has done. I have outlined the basics that one can do and check. Is it the valve? or the seals in cylinders ? Perhaps the op could post this question in the hydraulics section as there are experts over there like kennyd and JJ.
