IMPELLER/MOTOR REPLACEMENT Refer to Figure 2, and 3. 1. Remove unit from the tank or reservoir. 2. Remove fasteners (Ref No. 8) and washers if present (Ref. No. 7) that connect the volute base (Ref. No. 17) to the volute cover (Ref. No. 10). 3. Remove volute base, and gasket (Ref. No. 16). 4. Place an allen wrench through the slot in the top of the column and into one of the socket head screws of the shaft coupling. Rotate impeller counterclockwise until allen wrench stops against side of slot. Remove nut (Ref. No. 15) and then impeller from drive shaft by rotating each counterclockwise. IMPORTANT: Care should be taken to insure that same number of shim washers (Ref. No. 9), if present, is replaced behind impeller as were removed. These shim washers are located directly behind the impeller. Shim washers may or may not be present depending on assembly clearances. 5. Remove allen wrench from slot and then remove the four fasteners (Ref. No. 5) and washers or nuts (Ref. No. 4) that connect the motor (Ref. No. 1) to the column (Ref. No. 3). 6. Remove the motor with shaft (Ref. No. 13) and coupling (Ref. No. 2) from the column. 7. Measure the distance from the shaft coupling to the motor mounting surface. Record this measurement. 8. Loosen the two socket head screws, towards the motor, in the coupling. Slide the coupling/shaft from the motor. 9. To reassemble, slide the coupling/shaft on the motor. Replace drive key (Ref. No. 7) if removed (557? Series only). Position the coupling at the recorded distance from the motor mounting surface. Securely tighten all four socket head screws in coupling. 10. Install motor/shaft assembly into column. Secure with four fasteners and washers. 11. Install impeller, shim washers if any, and nut. Position gasket on volute cover and install volute base with fasteners and washers. IMPORTANT: If impeller strikes volute spacer plate (Ref. No. 11) before bottoming on shaft shoulder, add two 0.020” shims behind impeller. Reinstall impeller. 12. Place pump in an upright position. Rotate shaft/impeller. Impeller cannot strike volute base or volute cover. If interference exists, install or remove shim washers behind the impeller. (See “SHIM ADJUSTMENT” section) If shimming does not correct interference, repositioning coupling/shaft/impeller assembly on motor shaft may be necessary. VOLUTE SPACER PLATE REPLACEMENT The volute spacer plate is subject to wear only by abrasive liquids. If badly, worn this plate can be replaced easily. 1. Disassemble pump for access as described in IMPELLER/MOTOR REPLACEMENT, steps 1, 2, 3, and 4. 2. Remove two fasteners (Ref. No. 12) that connect the spacer plate to the volute cover. 3. Replace spacer plate. 4. Reassemble pump as described in steps 11 and 12. SHIM ADJUSTMENT 1. When installing a replacement impeller (Ref. No. 14), motor (Ref. No. 1), volute spacer plate (Ref. No. 11) or volute base (Ref. No. 17), it may be necessary to adjust the number of shims (Ref. No. 9) to insure proper runnin...
