remember to back out the valve a few turns under the big acorn nut on the side of the housing before attempting to remove top cover. I would follow your manual on this.
can you rig up a rope block set or a strap hoist over the hydraulic housing so you can lift the top cover and then reset it when you have it done?
Also, I would suggest a new piston along with the O-ring. But look at the cylinder close to be sure it isn't scored. I honed mine a little.
Spend plenty of time cleaning the mating surfaces for the top cover. I only put sealer in enough spots to keep the gasket from shifting as I set the top back on.
