The tightened pin must move easily in the piston.
Many report cracks extending down from the machined cut. The hole would normally be correspondingly worn but if not it would seem for moderate use a waste to scrap an otherwise good rod. A hole could be drilled just beyong the true end of any crack.The pinch bolt is supposed to be of special stuff. Ordinary 45 ton HT were labelled R and S was grade higher. I dunno what is avialable now. Allen key screws are genrally of tough stuff. Any bolt which has run not tight is at risk of fatigue failure.
