5. Press the brass fan rotor adapter onto the motor
shaft—make sure one of the set screw holes in the adapter
is aligned with the fl at spot on the shaft and make certain the
adapter goes on all the way up to the threads. If you can’t get
the adapter to go all the way, use a hobby torch to heat the
adapter fi rst. Then, slide it into the shaft.
❏
6. Add a small drop of threadlocker to the threads on the
set screws for the adapter. Then, use a quality 1.5mm Allen
wrench to tighten set screws.
❏
7. Test fi t only the fan rotor to the rotor adapter. If the head
of the set screw opposite the fl at spot is protruding from the
adapter and making it diffi cult to install the fan rotor, cover
the front of the motor with a cloth or paper towel and use a
metal fi le to fi le down the screw so the fan will fi t properly.
❏
8. Test mount the fan rotor to the adapter with the rotor
cone, the 3mm Phillips screw and the 3mm washer that
came with the fan unit—the HyperFlow instructions specify
using a 3mm x 8mm screw, but the 3 x 5mm screw included
with the fan may be used.
Hint: For optimal performance it is desirable for the fan rotor
to turn as concentrically (“true”) as possible. Test fi t the rotor
in different orientations around the adapter spinning it by
hand each time. When you fi nd the orientation that is the
truest, use a hobby knife to lightly scratch a small “X” at the
base of the rotor where it aligns with the fl at spot on the motor.
When you mount the rotor later, do so in this orientation.
❏
9. Remove the cone and rotor and set them aside.
❏
10. Mount the motor to the fan housing–you can use the
3 x 5mm screws included with the Ammo motor (and a drop
of threadlocker on the threads). Any set of holes in the fan
housing that align with the holes in the motor may be used,
but we used the outer holes in the motor. Use care not to
overtighten the screws so much that you damage the plastic.
❏
11. Glue the stator extension to the fan housing as shown
in the HyperFlow manual. Make sure the little notches in the
stator fi t around the housing.
