3-Point Hitch LEAKING LIFT ARM ?

Good pics woody,
I ordered the 2 O-rings from the parts schematic I have, hope they are right ones

Well, of course the O-rings were too small will try to match at local hydraulics shop tomorrow
I did dis-mantle & got a look inside & I am a little confused.
I got the outside bushings & the O-rings out, but could nor figure out how to remove the inside bushings, removal not needed anyway to replace just the O-rings.
Pictures added
Looks like the insides have to be removed to get shaft out.
The O-rings looked pretty good, the leaky side had a lot of oil on it, the non leaky side was dryer, bushings look like no wear also.
Can't figure out why this set-up doesn't leak anyway, after removing O-rings & outside bushings, arms & shaft had some play on both sides, vertical & horizontal.
I think I should have lived with the leak, or waited until leak much worse

Lift goes too high now
OK, Thanks to Circle G I did get right O-Rings
I marked the lift arms when removed, but I must have re-installed wrong.
Lift now does not engage until nearly at top, Pressure is great "Too Much"
With weight (Bush Hog) lowers too ground
Lifted too high & broke both stabilizer chain eye bolts
Removed top again & can't figure out exact location of lift arms on shaft
Any one have details ?

Does lift need adjustment or just arms re-locate ?
Thanks David

Mine has an adjustment cable attached to the housing just below the seat. See pic below. Don't know if it will help at all. Different brand tractors.

While reinstalling the 3-point piston on mine, the hyd fluid was drained, so I was able to move the lift arms by hand and mark the high/low points. Then I used those marks to adjust the stops attached to the handle. Could you do something similar on yours? But maybe using power to adjust if you don't want to drain the fluid.

I didn't remove the lift arms on mine, so I can't help with what to look for inside them. But I could take photos of the outside if you think that might help with reinstalling your lift arms. I'd say that you don't need to adjust the stops attached to the handle like I did, because yours were probably right when you started. So if you can just find the right position for the lift arms when reinstalling them on the shaft, you should be good to go.
