OM-00714 10 SERIES MAINTENANCE AND REPAIR PUMP AND SEAL DISASSEMBLY AND REASSEMBLY This pump requires little service due to its rugged, minimum-maintenance design. However, if it becomes necessary to inspect or.replace the wearing parts, follow these instructions which are keyed to the sectional view(s) (see Figures 1 and 2) and the accompanying parts list(s). - Page 35 OM-00714 MAINTENANCE AND REPAIR Disengage the machine screws (75) and pull the check valve seat (70), gasket (69) and check valve assembly (76) from the suction port. Inspect the check valve parts for wear or damage and, if replacement is required, remove the hardware (77 and 78) securing the valve weights (79 and 81) and check valve (80).
- Page 36 10 SERIES OM-00714 MAINTENANCE AND REPAIR Inspect the impeller and replace it if cracked or badly worn. Slide the impeller adjusting shims (23) off the impeller shaft. For ease of re assembly, tie and tag the shims, or measure and record their thickness.
