New seal rings must be preloaded before they are installed to prevent them from being damaged or broken. There is a correct method to preload new seal rings prior to installation. Place your hands on each end of the seal ring, and pull (wind) the ends several inches past each other or until they almost make contact. Use care to keep the ring shaped like a circle. This will make an even bend (or ring "set") all around the ring. When the seal ring is in the groove of the hub, the ends must butt together lightly. Do not bend the seal ring. This does not make an even bend all the way around the ring.Do not attempt to use this method to preload a used seal ring. Also, do not use this procedure for cast iron seal rings. This will cause used or cast iron seal rings to break.
