kennyd said:Richard, is it possible that they are not "wrong" but "different"? Have you tried to install them?
There are updates in parts all the time...Maybe you have the latest and greatest.
Good afternoon, Kenny --
As you know from our phone conversation, this was exactly the situation (thanks!) and I now have two of the cylinders rebuilt; a quick lunch break and I'll finish the others.
When I first compared the seal kits yesterday, I was hot (95 here in Central Texas) and frustrated that I was working at maintaining something instead of being productive getting tasks done -- not a good time to work! The first seal that I compared was the main piston seal and the new one was a completely different design -- no taper, about 4X as thick as the old and was in a separate plastic bag within the kit. I quickly concluded (erroneously) that this must be the wrong kit.
After Kenny's suggestion, I systematically put the old sealsand the new seals side-by-side. There were only two differences: the main piston seal (described above) and a flat plastic type seal that was a different color. Then, I inspected another old piston that had not yet been disassembled and realized that this was the failure component that was causing the leak down. I'll post another message later that has pictures to illustrate the failure and the replacement seal and how it overcomes the old seal's weakness.
Again, Kenny, many thanks for helping out this Memorial Day!
Richard
