Assembly 3 – Motor Housing
The motor housings consist of four parts; two motor mounts and two
axles which transfer power from the motors to the wheels. The two axles
are identical and can be used with either motor mount.
Press an axle into each of the motor mounts. Make sure you face each
axle in the opposite direction as shown. To fit the axle insert the short
end in first and then push the long end into its slot.
Assembly 4 - Motors
There are two motors provided, and two worm gears used to transfer the
rotation of the motor shaft to the axle in the motor housings.
Ensure that the terminals of the motors have not been flattened.
Flattened terminals will make poor contact while angled terminals will
make good contact. If the terminals have been flattened then gently lift
them up.
Push the worm gear all the way onto both the motor’s shafts. The worm
gears will fit onto either motor shaft.
If pushing the worm gear onto the motor shaft is difficult then use a hard
surface to push against.
