Fitting instructions for a Scalextric motor pinion gear - 9z

This process does not require specialist gear pullers or other tools
1. Place the gear on a hard surface

Warm the gear to at least 30 degrees centigrade which will allow the plastic to stretch over the motor shaft without splitting. Simply holding the gear in a warm, closed hand for a few minutes will be sufficient or soak the gear in a container of warm water for a few minutes.

Place the gear on a hard surface with the circular flange facing upwards.
2. Gently push the motor shaft into the gear

Gently push the motor shaft into the hole in the centre of the motor pinion gear. Use a constant gentle downward pressure.

Continue until the motor shaft is right through the gear and touching the hard surface.
3. Pinion gear partly fitted
 Here the motor pinion gear is partly fitted. The shaft is flush with the face of the gear.
4. Pressing the gear into the final location

Position the motor shaft over a void or hole in the hard surface. In this picture a gap in the jaws of the pliers is used.

Again apply constant and gentle downward pressure to push the gear along the motor shaft and into the correct final position.
5. Motor pinion gear fitted

Here the motor pinion gear can be seen in the correct final location along the motor shaft.

The exact location may depend on your specific application.
