does require replacement, proceed as follows:
10. Pull power rotor (22) assembly forward from pump to expose mechanical seal (27) assembly which is
mounted on seal sleeve (26).
11. Remove inner spacer (29) and outer spacer (30).
12. Remove seal sleeve (26) from power rotor (22) shaft. Removal of seal sleeve (26) will also remove
