1.Remove the piping to the ports and remove the capscrews securing the pump to the bracket. Support the pump with an overhead hoist if possible. Use the M10 x 120 capscrew (jackscrew) in the bracket to separate the inner magnet from the outer. (See Figure

Sequence 10).

CAUTION !

Use extreme caution, when pulling the in- ner magnet away from the outer magnet (see Figure 10). Do not place your fingers between the pump mounting flange and the face of the bracket. If you do not completely pull the pump out it will snap back and could pinch a finger or hand. Once the inner magnet is removed from the bracket be careful setting it down as it will

attract any iron or steel object.

2.The canister will contain some liquid, therefore use care while removing from the pump and pull it straight off.

3.Remove the two 6mm buttonhead machine screws and the set collar. Insert a brass bar through a port between two rotor teeth and remove the locknut (See Figure 11). Slide the inner magnet off the shaft. Do not forget this is a very strong magnet. If further pump disassembly is required, refer to Step 7 of PUMP DISASSEMBLY.

4.Do not remove the O-ring unless it is bad, especially if PTFE (derivative) encapsulated. If a new O-ring is required, follow instructions in the ASSEMBLY section on page 10.

5.You should be able to visually inspect the outer magnets from the end of the bracket. If removal is necessary, start by removing the (4) capscrews (See Figure 12) and separate the bracket from the motor or bearing carrier. Loosen the 2 setscrews on the outer shell hub and slide the outer magnet assembly off the shaft. If the unit features a bearing carrier, refer to Page 9 for disassembly of the bearing carrier housing.
