PUMP DISASSEMBLY
WARNING!
Refer to DANGER & CAUTION listed on page 2 before proceeding.
1.To drain the liquid being pumped, remove the two (2) drain plugs located in the bottom of the casing. Once the liquid has drained replace the plugs.
2.Refer to Figures 4, 6, 7 & 8 for names of parts.
3.Mark the head and casing before disassembly to insure proper reassembly.
4.To inspect the head and pin assembly and idler and bushing assembly, remove the head capscrews.
5.Remove the head from the pump. Do not allow the idler to fall from the idler pin. Tilt the top of the pump head back when removing to prevent this. Avoid damaging the head shim set since all shims are required to maintain end clearance.
6.Remove the idler and bushing assembly. If the idler bushing needs to be replaced, see “INSTALLATION OF BUSHINGS” on page 10. If further disassembly is required, the pump must be separated from coupling. Refer to “DISASSEMBLY OF COUPLING” on page 8 before proceeding with Step 7.
7.With the inner magnet removed, now remove the pump shaft key. Remove the outer thrust washer. The rotor and shaft may now be removed by tapping on the end of the shaft with a soft face hammer (If a soft face hammer is not available a regular hammer may be used with a piece of hardwood).
8. Remove the inner thrust washer from behind the rotor.
The casing should be examined for wear, particularly in the area between the ports. Clean all other parts thoroughly and examine for wear or damage. Check the bushings, idler pin and thrust washers; replace if necessary.
When making major repairs, such as replacing a rotor and shaft, it is advisable to also install a new head and idler pin, idler and bushing, and casing bushings. See “INSTALLATION OF BUSHINGS” on page 10.
