Release the Compression Coupling
Follow these steps to loosen the respective motor from a machine shaft.
RDB-x290x and RDB-x410x Motors
1. Seat a 6 mm hex driver on the compression coupling bolt.
Access the compression coupling bolts through the holes labelled A.
• The RDB- x 290 x motor has six (6) compression bolts to loosen.
• The RDB- x 410 x motor has ten (10) compression bolts to loosen.
Refer to the diagram on page 15 for the hole locations.
2. Release the compression coupling by lightly tapping the hex driver with a
hammer.
3. Repeat steps 1 and 2 to the compression coupling bolt directly opposite the
bolt accessed most recently.
Use this alternating pattern until all compression couplings are released.
RDB-x4103 Motors Only
1. Seat a M6 x 1 x 120 screw or threaded rod into either hole D.
Access the second-stage compression coupling bolts on a RDB-x4103 motor
through the holes labelled D.
The RDB- x 410 x motor has two (2) second-stage compression bolts.
Refer to the diagram on page 15 for the hole locations.
2. Release the compression coupling by tightening the screw/rod until the
coupling loosens.
3. Repeat steps 1 and 2 to the compression coupling bolt in the other hole D.
TIP
The RDB-x4103 motor has a two-stage compression coupling.
Release the first and second stages by performing both steps below, starting
with the initial step that is common for all RDB-x290x or RDB-x410x motors.
