After getting advice from another vortexer about pinning my crank while I rebuild my G60 I found this great thread.
So, what's going on here? Is the keyway in the crank sprocket failing?
I don't believe I have any signs that this failure was imminent for me. However, is the general practice to replace the +20 year old sprocket and bolt or can the sprocket/bolt be inspected to determine if reuse is in order? Again, nothing has failed for me....yet....
