Has anyone ever seen a crank that had the shoulder of the snout in which the lower crank sprocket backs up against be machined too much? In other words, I have an engine over here that has a crank that seems to be allowing the lower crank sprocket to slide on too far which is causing the timing chain to not be in perfect alignment. I tried another timing gear set and found it to be the same result. I guess I could shim the lower sprocket out some to fix this condition. Has anyone else seen this issue? This is a first for me. Also a first with this particular brand crankshaft also.



any chance you could tell us what size engine your working on and what brands of parts your using?
