Also, when I tried a = new pin (4/0) in a hole with no "black" in it, it was jumpy too and did seem = too tight (torque 160).  I tried tuning pin driving fluid (APSCO) in a = couple of the holes.  At first it seemed to do the job and eliminate the = jumping, but a couple of hours later they were almost as jumpy as the others. = Any ideas would ! be appreciated!</FONT> </FONT></BLOCKQUOTE></BODY></HTML>
