[C320-list] Changing the prop in cold weather

Wed Jan 2 09:30:51 PST 2013

The shaft key stays in place until the prop comes off. The key way in the shaft is open ended aft, so it won't prevent the prop from coming off. Be patient and tighten the hub puller slowly. Make sure it remains centered on the hub of the prop. Good luck!
