New Hydraulic Ram Seals
Well we finally got all of the new ram seal kits, and started the process of dismantling the rams and re-fitting with the standard seal kits. The image here shows one of the 40mm pistons, with the wear rings removed and the low friction seal still fitted. In order to get the fitted seal off, we had to cut through them, thus destroying them in the process. To get the new seals on wasn't easy.. at least not without the right tools, so we made our own expansion sleeve to fit the end of the piston, then slowly pulled the seals into place over the sleeve. A bit of a mission, but all 3 rams are now done and back together, ready to be refitted to the leg.
