1. If replacing the encoder cable also, unplug the
encoder cable (AE/AF)from the control board and
the encoder and remove.
2. Loosen the 2 hub set screws (AA) using the
included .050" hex wrench.
3. Remove the 2 mounting screws (AC) with a
Phillips head screwdriver.
4. Pull encoder (AB) off of rotor shaft.
NOTE: This procedure only requires the removal of
NOTE: NOTE:
the 2 Phillips head mounting screws. All other bolts
should remain in place.

1. If replacing the encoder cable (AE/AF) also,
place the encoder connector cable through the
motor housing.
NOTE: NOTE: The encoder connector (AE) end is the NOTE:

2. Slide the new encoder onto the rotor shaft.
3. Apply a small amount of blue (medium) thread
locker to the 2 Phillips head mounting screws
(AC) and secure encoder mounting flange (AB)
to motor housing (AD).
4. Remove the 2 set screws (AA) from the encoder
hub using the included .050 in. hex wrench.
5. Apply a small amount of blue (medium) thread
locker to the set screws (AA) and screw back into
