As a machinist and a bike enthusiast I think you're seeking the Holy Grail here in trying to 'tighten it up a bit'. You're within tolerances and should spend your time, money and effort elsewhere. You're good. HOWEVER.... I will go to bended knee if Mutt disagrees.

Thank you for the quick reply. My machine is a 63 Scat and the pins measure .121" It has been apart before, someone really tore the plates up. The rod and crank pin look good, I think .122" pins would tighten it up. Does anyone sell these oversize rollers.
Thanks again, Scott

depends on what year/ 48-60 models use .250" x .490 long
61 to 66 use .120" diameter needles

Can someone please tell me what the stock dimension is
for the crank pin roller bearings?
Thanks, Scott
