Nothing looks worn but I know that something being old and brittle could be the issue. It seems to me the tensioner drum itself has to come apart so you can get at the seals or o-ring at the bottom of the piston. I cannot see how to open this. Does anyone know how this comes apart? I have the Navtec 10 - 7 which is the square sided drum Thanks John on Enterprise
