Use the following method to preload the new seal rings. a. Place your hands on each end of the seal ring. Pull the ends past each other by several inches. The ends should almost make contact. Be careful to maintain the circular shape of the ring. This will make an even bend around the ring. b. When the seal ring is in the groove of the hub, the ends should lightly make contact. Do not bend the seal ring. This will make an uneven bend around the ring. Note: Do not use this procedure to preload a used seal ring. Do not use this procedure for cast iron seal rings. This procedure will cause used seal rings or cast iron seal rings to break. Illustration 4 g00620528 6. Align the oil holes in manifold assembly (22) with the holes in housing (13).
