Okay girls and boys, I'm thinking I need to replace the rings (and who knows what else) in at least the horizontal cyclinder of my 97 M900. I'm wanting to get all the parts and tools together before I begin the project, so I don't have to wait so long for parts. Can you give me a detailed "parts list" of what it will require to do the job (rings, gaskets, seals, etc, etc)? Also, what special tools will I need (such as a ring compressor, etc)? Thanks for your help in advance. . .
