pfrederi 17,881 #2 Posted June 13, 2012 See page 56 of the Sundstrand Hydro manual for instructions on pump shaft seal replacement. The seal is CR 7474 National 480821. CR has a 7475 that has a double lip design that may be better. See this D200 thread about the seal...same seal Share this post Link to post Share on other sites
