Well, good luck. I have a Model XER-6451, circa 1976. Called the old Wards parts line (now belongs to Sears) and no help there. Called Campbell-Hausfeld parts hotline, and no help there either. Common response was that the unit is too old to expect to find any spare parts. Unless I can snoop out some parts through other manufacturers, I'll probably be scrapping my unit. If you find any parts, please write me.
