+The damage below was caused by using the wrong seal (83-90 seal with the metal shell) in the 77-82 outer plate with the counterbored seal hole. The plates (when installed) are very close together and the 83-90 seal doesn't sink down flush to the plate. This puts added resistance to the pump turning and as seen below, the seal will grind away at the counterbore and/or lock up the pump. \\
