Front Axle Assembly
1. Place one of the front wheels flat on the table. Insert one end of the remaining steel axle into the wheel until
the end of the axle is flush with the opposite side of the wheel.
2. Slide two nylon spacers onto the free end of the axle.
3. While keeping the spacers on the axle shaft, slide the free end of the axle into the other front wheel until the
end of the axle is flush with the opposite side of the wheel.
Attaching Axle Assemblies to Chassis
1. Position the notched chassis on the table so the notched end of the balsa wood sheet is hanging over the
table edge and Lines B and C are facing up.
2. Carefully position the rear axle assembly so:
• Gear I is centered in the notched area of the chassis.
• The axle is positioned along Line B.
• The nylon spacers are positioned within 1/16" of each wheel.
3. When the rear axle is positioned as described in Step 2, use small C-clamps or ask a friend to hold the rear
axle assembly in the correct position. Now gently apply a bead of cool-melt glue along the sides of the nylon
spacers where they touch the chassis. Hold the rear axle assembly in place until the glue cools.
4. Place the front axle assembly along Line C. Position the axle so the wheels are equidistant from the chassis.
5. Slide the spacers to within 1/16" of each wheel. Hold this assembly in place and gently apply a bead of cool-
melt glue along the sides of the nylon spacers where they contact the chassis.
6. Hold the front axle assembly until the glue dries.
Attaching Motor Assembly to Chassis
1. Remove Gear F from the gear font and cut off any excess plastic between the teeth of the gear.
2. Insert the shaft of the motor into Gear F to within 1/8" of the body of the motor.
3. Set the chassis on the table with the axle assemblies facing down.
4. Using a cool-melt glue gun, create a 1/2" x 1" rectangle of glue about 1/8" deep (Figure 5).
5. While the glue is still liquid, place
the motor on its side (with vent
holes up) on the glue so Gear F sits
directly on top of and engages Gear
I (Figure 5). Be sure not to block
the vent holes with glue. Hold the
motor in place while the glue cools.
6. Apply another bead of cool-melt
glue behind and in front of the
motor (Figure 5). This will keep the
motor in place if the vehicle comes
to a sudden stop or crashes.
7. If the motor dislodges, use the tip
of the glue gun to soften the glue
on the chassis where the motor
was. Add a small amount of glue
and reattach the motor as you did
before.
