3. Press the 2mm fan rotor adapter onto the motor and
tighten the set screws against the shaft. Allow a small
amount of clearance (1/8" [3mm]) between the base of the
adapter and the motor to prevent binding. A 3/32" [2.4mm]
hole can be drilled into the side of the fan housing 9/16"
[14.3mm] from the front edge to insert an allen wrench for
the fan adapter set screws.

4. Fit the fan rotor over the brass fan adapter and thread
a 3 x 8mm phillips screw with a 3mm washer to hold it in
place. Be sure to use threadlocking compound on this screw.

5. Cut a portion of the aft cone away for motor cooling and
to allow the motor leads to pass through. For most motor
applications, the aft cone should be approximately 1-1/4"
[32mm] long after cutting it.
❏
6. Attach the aft cone to the fan housing with a couple drops
of CA glue. Excess glue will make it difficult to remove the
motor from the housing should it be necessary in the future.
