Mark; With the new information you have given us that probably was not done by S&S. They never would have kept the old backchecks and the spacing on their keyframes is very very good. Probably a retrofit by someone else. Vedigris is an indication of some petroleum based product having been used at some time in the past I don't think that it would have been caused by silicone. Obviously this is one of those situations where silicone, or any lubricant, is not apropiate period. Usual scenario on teflon bushings (first step)-a. bushings rattle (second step)-b. bushings repinned with wrong pins and/or too tightly, to stop the rattling (third step)-c. bushings not rattling but action heavy/sluggish (fourth step)-d. lubricate action centers to solve sluggishness problem (fifth step)-e. customer calls Mark or another technician and says this really feels heavy and nonresponsive to me. Can we (when this is said you are in trouble) do anything about it??? Steps have no set time frame but they are usually all present ! Do the best you can and remember for future reference.
