Undo the bolt, pull hard.

If you're having difficulty, try tapping the threaded part in the middle with a hammer while pulling the the arm.

remove cap from nut, then undo the nut. then it may be a bit stuck, wiggle from side to side or tap gently with a hammer to loosen the arm from the splines on the motor and hey presto!
