Procedure

Parts and Tools

Removing the Drum Motor

1. Disconnect any connectors from the motor, and from the connectors bracket, and then disconnect the connectors bracket.
   
   
   
   
2. Use the drum holder assembly to hold the drum, as shown.
   
   
   
   
3. Remove the vacuum swivel from the shaft, as shown.
   
   
   
   
4. Insert the drum motor nut key jig into the drum motor nut.
5. Using the drum holder assembly on the other side of the drum to secure the drum (as shown in step 2), insert the torque meter into the drum motor nut jig and remove the drum motor nut. You may need to use some force to remove the Loctite adhesive.
   
   
   
   
6. Insert the film around the motor rotor to prevent contact between the stator and rotor magnets. Most of the film should fit in.
   
   
   
   
7. Remove the bolts that secure the drum motor, and then pull the motor out.

Reinstalling the Drum Motor

1. Insert the new motor, apply Loctite to the bolts, and then tighten the torque bolts to 350 kg/cm (300 lb/in).
2. Apply Loctite to the drum motor nut, and then tighten the nut to a torque of 1000 kg/cm (870 lb/in.).
3. Reconnect the vacuum swivel, applying Teflon tape to prevent vacuum leakage.
4. Reconnect all the motor connectors.

Test

Activate the drum motor at varying speeds and verify that it rotates smoothly and quietly.
