Here are a few quick supplements to Jack's good advice: 1. The bar through the knee joint to use for jacking up the plane -- when I replaced mine, I used a pipe that wasn't strong enough. It worked, but it bent. Try looking for a solid bar or pipe with very thick side walls with the outside diameter that will fit through that opening in the gear knee joint, then keep it for future work.
2. If the seals leak, your cylinder may be out-of-round. I've heard discussions in which it was recommended to change back to the cup shaped seal since that will change shape to conform to out-of-round cylinders. I seem to recall that you have to change brake fluid type if you make that change. The cups are available from Skyport () as kit SMK 61 for $25.95. (The cup type seal was used on the older Coupes up through serial number 812.) 3. If you haven't replaced them recently, when you do strut maintenance is a good time to put in new rubber donuts since you'll have the assembly taken apart anyway.
