Jack,>From what I could find (after doing a quick web search), your assumption wasright. #520 is a size of motorcycle chain, and the "5" refers to the pitch(5/8"), same as the 5 in ANSI#50 roller chain. From what I could find, thepin diameter for the outer links in both cases is listed as 5.08mm (or0.200"). This should give a nice non-binding fit with a 3/16 clevis pin. Youdon't need a tight fit - and likely wouldn't even want the fit to be tight(for ease of assembly). I believe the motorcycle chain is even tougher thanstandard roller chain.Bill C _____
