Rare 2 cylinder RAM trim/tilt system on a 1979 HP 200 Merc needs a Cylinder replaced

[leblancjoel]

Fluid leak coming out where the cylinder is threaded at the bottom (right cylinder, red fluid). I am trying to remove the whole cylinder and replace it with another one. I have attached some photos to help. There seems to be a shaft that runs through the bottom of the transom, through both cylinders. You can see in the parts photo. I need to know how to remove it. It is threaded. Then, at the top of each cylinder, where the piston arm attaches to the swivel bracket, there seems to be a threaded pin that runs through each cylinder. Any advice on how to remove these? I am simply trying to remove the one cylinder for replacement. Photos should help
