Repair7-14P/N 7105144G 2008 Nordson CorporationVersaBlue_NWReplacing CouplingNOTE: All new couplings have square indentations (pockets) for thecoupling broken monitoring magnets.WARNING: Strong magnetic field. Risk of injury. Maintain 0.3 m /12 inches clearance between magnets and magnetic data storagedevices, sensitive electrical or electronic equipment, and persons withpacemakers.Risk of injury due to strong magnetic attraction.The magnets can break when handled incorrectly.WARNING: Hot! Risk of burns. Wear heat-protective gloves.1. Disconnect the melter from the line voltage.2. Detach protective panels and insulation blanket.3. Turn the coupling far enough that assembly work can be performedeasily.4. Allow the coupling to cool; the following tasks can be performed bestwithout gloves.5. Release the coupling on the motor side.6. Mark the position of the motor, then slide back the motor bracket (withthe motor and coupling broken-sensor) in the slot.Fig. 7-237. Release and detach the coupling from the pump side, then dispose of itproperly.8. Unscrew the sensor from the sensor bracket (The sensor will be usedagain) and replace the old sensor bracket with the new one from thespare parts kit Coupling.9. Slide the magnets into the square indentations on the surface of thecoupling.10. Degrease the edge of the coupling (e.g. with spirit) so that the adhesivelabels remain affixed.11. Stick the two warning labels from the parts kit to the edge of thecoupling, next to the indentations.12. Slide the motor in the slot until the motor shaft touches the pump shaft.The two shafts must be aligned vertically and horizontally. Then slide themotor back again.13. Attach the new coupling to the pump shaft without using force (no joltsor pounding).
