9N Lift cylinder question

So my friends' 9N (year unknown) won't hold the load up. Got the lift cylinder and piston out and the oddest thing. The piston is a 3 groove type, but there are O-rings installed, not metal ones. Piston miked out to 2.4995. Cylinder bore at 2.5070 at the opening. Using a in/out caliper, don't have anything to reach down and check middle or end. Any thoughts on this weird setup? Tempted to replace both and be done with it. Should I go with the 3 groove and metal rings or the one groove and O-ring? The cylinder doesn't look to bad, couple of inch long scratches that may hone/polish out.

Whoever did it didn't use the NAA o-rings. I think they probably went to NAPA and just found some to fit. They also used RTV instead of a gasket on the cover. Got my parts from YT, didn't realize the gasket set came with the o-ring and washer, and I had ordered them separately. Now I have spares. Also found the draft control plunger bent, the spring plate buggered up, the bushing that goes inside the draft control spring cracked, and no felt washer. Got some parts coming from MO where a guy had a lot of lift cover parts on eBay for $20. The owner and I talked about overhauling the pump, but the "if it's working don't mess with it" won over the "as long as we're in here this far" idea.

It depends on how badly worn the cylinder is from the original steel ring-type piston. I never heard of someone putting rubber O-Rings on an original 3-ring piston before. It could be why it leaks. The steel ring style piston groove diameters(s) and the NAA rubber O-Ring groove diameter are not the same. The NAA style piston that uses the rubber O-Ring also uses a leather backup-washer/wiper. Me? What I would do since I had to pull the top cover off anyway, is to replace bot the cylinder and the piston with new. Evaluate if the pump needs to be pulled too and rebuilt -why not, you've gone this far? That way it'll all be good for many years to come before it needs to be yanked again. I'd stay with the NAA piston, rubber O-Ring, and leather backup washer too, but if you want/need a new 3-Ring piston, I have a new one I'd gladly part with. Email is open...

The piston is spot on and was probabably replaced when the o-rings were added. I'll bet it was leaking down and someone decided he'd do a cheapie :roll:
The cylinder is .007 over. That is a LOT of wear and I am not surprised it still leaks - especially with the ill-fitting rubber o-rings.

I would not reuse either and replace both piston and cylinder using the o-ring piston. Do it right and you won't have to worry for decades to come.

If you have more money than time (or skill) just buy a new cylinder. It's very easy to hone out that cylinder too far.

If you go to the o ring piston I would replace piston and cylinder. O rings do not like a rough finish. you could just put new metal rings in what you have.
