Upon reinstalling the crank balancer on my 617, it seems that the alignment pins grew some in width. The pin position on my engine is slightly offset so I don't have the problem of installing the balancer 180 degrees off. As I was tightening & checking for proper alignment, when it finally all came together, the pins seem to have their edges shredded some-like a few thousands of an inch. Talk about a tight fit! I checked the crank timing with the opening of the valves per the manual & it's right on the money-so I guess I'm happy!?
Just don't like to see stuff like this when putting an engine together. Paul.
