The flywheel key was actually prodruding from the inside face of the flywheel hub.The key had been hammered in until it got to the end of the keyway in the crankshaft.The keyway on the crankshaft then curved up at the end (it was just how it was machined at the Lister factory).Whoever refitted this key then kept on hammering until the end of it followed the curved path of the keyway,pinching it REALLY tight at this end.How the cast iron flywheel hub never cracked i dont know with the amount of force that must of been on it !!.To make matters worse i never had any really long drill bits so had to make them longer by welding a longer shank on them until they were approx 12″ long.I was very pleased though when the key finally came out :).
