Loosen the Compression Coupling Bolts
Follow these steps to loosen the compression coupling bolts prior to releasing the
compression coupling from the shaft.
1. 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
for the locations.
2. Moving in a circular pattern, use a 6 mm hex bit to loosen each compression
coupling bolt.
3. Loosen each bolt two (2) revolutions beyond finger-tight.
WARNING
Loosening the compression coupling bolts more than two (2) rev-
olutions beyond finger-tight may disengage the compression cou-
pling from the rotor.
