They state they have carried out extensive studies that refute claims that graphite can cause centers to seize after some use.  Lubrications usually have a temporary affect in my experience, but not always.  My general solution is to re-pin, reaming the bushing very lightly to get some of the graphite out, and working some telfon powder into the bushings before inserting the new pin.  Seems to allow for a tighter pining for same friction levels. Cheers RicB <blockquote> List(s), I've noticed something that I don't understand on a few actions with Renner parts.  Initially, the pinning is just right (either came that way or were made that way).  Eventually, some of the pinning becomes too tight.  When I apply the smallest drop of lubricant, the pinning that was too tight immediately becomes too loose.  This has happened with both hammer and repetition lever centers.  I don't get it.  Has anyone out there had a similar experience?  Does anyone have any idea what is going on?
