(15)Remove flexible coupling by tapping out the groove pin (8) and then withdrawing coupling from pump shaft. The shaft (26) can then be pressed out of the bracket (7) by tapping or pushing on the coupling end. An arbor press can facilitate this operation.

(16)When the shaft is pressed out it will still be assembled to the rotor (19), the rotor bearing (20) the bearing guard (23), bearing guard spacer (22), and retaining ring (3).

(17)Remove plastic plug (16) and retaining ring (18) using a special pliers which can be obtained from Vanton or a local industrial distributor. The shaft can then be pressed out of the rotor.

(18)Remove the bearing guard (23), bearing guard spacer (22), and bearing retaining ring (3) from the plastic rotor, using special internal pliers obtained from Vanton or a local industrial distributor.

(19)Using an 11/16 " plug, press out outboard bearings (5) and bearing spacer (6). The pump is now completely disassembled.

In reassembling the pump, attach the flexible coupling to the shaft, using the groove pin (8) and then install the bearings (5) and the bearing spacer (6) onto the shalt as shown in Figure A-3. Make sure the outermost outboard bearing rests firmly against the coupling shoulder. This entire subassembly can then be inserted into the bracket.

The rotor (19) should be completely outfitted with rotor bearing (20), bearing guard (23), bearing guard spacer (22), and retaining ring (3) prior to installation onto the shaft, which previously was installed into the bracket.

The rotor should be installed onto the eccentric portion of the shaft protruding through the bracket by supporting the entire bracket unit in this fashion, Insert a 1/2 " X 5" long rod through the coupling end into the hole of the shaft. Set the rotor on end, lower the shaft into the rotor and gently tape the inserted 1/2 " rod or use an arbor press until the rotor is ‘’home”. Install rotor bearing ring (18) and replace plastic block with Flex-I-Liner

(16)as previously described. The subassembly can then be bolted to the motor and while this operation is not particularly critical due to the unique coupling employed; nonetheless, good practice dictates that the faces of the bracket and the motor, which are to be bolted together, be clean and free from burrs.
