is there something I can do to this valve to keep the rear cylinder from creeping down? I read somewhere that there are O rings that can be replaced? The rear cylinder was bought new 3 years ago so I don't believe it is a cylinder problem.

Forgot to attach...

Best to do a leak down test on the cylinder first by putting a valve in the line and once in the up position turn off valve if it still sags then it is the cylinder if not then the valve. Cheaper to test than to just replace parts. Even new cylinders can be bad.

On the input or return side? I imagine it would be the return hose

There is a check valve right in front of the seat support box. It looks like a solid metal rectangle. That s where the check valve o-rings are.

Mine doesn't have that check valve set up.. hoses are straight from the auxiliary valve to the cylinder

There are 2 plugs on the outside face of the valve. Are those to plumb in a set of remotes? Assume the flow to those ports are not controlled by the vertical spool valve.

Think the problem is in that check,retard valve ahead of the seat.

I don't have that check valve. Hoses run from the aux valve to the cylinder

the check valve on the platform is to stop fast hitch from coming down
too fast NOT to hold the arms up. The valve on the lift all does that

Okay, then can that aux valve be rehabbed or should I just put an in-line check valve on the return line?
