Replace the End Cover
Follow these steps to align and secure the end cover in its original position.
1. Verify the O-ring is in position on the outside of the end cover.
2. Rotate the end cover so the alignment mark on the cover aligns with the
corresponding mark on the motor housing.
3. Tighten each pan head screw to secure the end cover on the motor.
• The RDB- x 290 x motor has eight (8) screws to tighten.
• The RDB- x 410 x motor has eleven (11) screws to tighten.
Remove the Motor From the Machine
Follow these steps to remove the motor from the machine shaft.
1. Remove the four (4) mounting bolts securing the motor frame to the
machine.
2. Slide the motor off the machine shaft.
TIP
If the motor is locked to the machine, use the threaded holes adjacent
to the mounting holes to separate the motor from the mounting surface
of the machine. Insert at least two bolts in diagonally opposite holes to
do this.
• The RDB-x290x motor has M10 holes.
• The RDB-x410x motor has M12 holes.
