    Default Rockshaft Lever Lifts Loader

    I am working on a JD 67 loader that痴 on a 750 tractor. I couldn稚get any response on the lift so I replaced the hydraulic oil and cleaned the screen. Still no lift when I just pull the lift lever on the control valve. However, if I pull on the lift lever while simultaneously pulling slightly on the rockshaft (rear hydraulics) lever, the loader lifts right up. But without slight pressure on the rear hydraulics the loader won稚 lift at all. Any ideas why this is happening? Could it be air in the lines? Something else? Any suggested fixes? Thanks!

    If all you did was change hydraulic oil and clean the screen - then as you suggest - air in the lines. Simple and easy fix - - just work it out.

    There is a pipe plug the had to be used to give you power beyond. It's been way to long ago for me to remember where it went. Just bring it up so maybe someone else can remember.
