Long 680 Hydraulic Cylinder Replacement Help

goebelmj · Mar 30, 2022

My Long 680 has severe lift problems. I plan on replacing the cylinder/piston/seals.

Is there any advice and/or guidance to help me tackle this task?

Thanks all in advance,

Are you sure it's the cylinder and not the pump? I've got an Oliver 1365 which is a Fiat 640. The pump went bad on that over time
and it got where after lifting 15-20 round bales and moving them off the field, the 3pt wouldn't even lift with nothing on it.

Pretty sure but not 100%. My front end loader is working fine so I suspect something in the 3 point assembly is causing the problem. I've pulled and cleaned the three indicated in the attached pic.

OK ya, my loader is plumbed to a separate pump just above the PTO shaft,
