Loader JD 70 loader

I have a 1997 755 with a 70 FEL that works fine except the dump function is quite slow. Any suggestions?

If you push out the hinge pins, do the cylinders advance and retract together and at much higher speed? If you have quick disconnects, look for one that's not seated properly. Also, try switching the raise/lower with dump connections and see if the problem goes with the hose lines. On my 80 loader, a pinched metal line on the cross tube was the culprit. Its either oil flow or a restriction. See if you can isolate it. If you have another cylinder lying around, try it on the dump circuit. I run quite a few different attachments on the loader lines via the quick disconnects. Even 1-way cylinders (as in mower header and cement mixer dump).

Thanks very much I will try that.

If the cylinders don't match each other "speed wise" and you've eliminated any problem lines or disconnect fittings that are loose - the slowest cylinder might have an internal leak and the hyd fluid is not properly pressurizing the cylinder.
