8. While each screw is still warm from heating, use a 5mm
hex key to loosen the 4 screws (B). A low-power impact
driver may be helpful, but use caution to not sheer the
screws or cam out the heads.
9. Using a 5mm hex key, remove the six screws (C) that
secure the drive hub to the rim. (The hub is lightly pressed
to the drive disk (F), and will come loose later.)
10. Turn the steering wheel so the other side of the motor is
facing outward.
11. Insert the four wheel puller bolts (D) into the threaded
holes of the drive housing, and hand tighten them until
they equally touch the metal rim of the tire.
12. Using a 5mm hex key, gradually tighten each bolt at about
1/2 to 1 turn at a time. Work in a crisscross pattern so each
bolt pushes the wheel off the main bearing (E) equally.
(The wheel hub will come free after just a few turns.)
For reference, the wheel/tire presses over the main bearing (E). The drive hub is lightly pressed onto the
tapered drive disk (F) of the gearbox.
