hi members, I own a craftsmen mower that uses 611154 flywheel key. the key was sheared so badly that I can't determine how it goes on the crankshaft. can someone help with this? its a really odd looking flywheel key. thanks.

Vector keys are installed w/ the tab part down. 35 ft. pounds torque. Tie the zone control down when you slide the flywheel on so it will line up better.

The shorter edge fits into the crank.
