Combine the axles and clips by pressing a "T" shaped end of each axle (each axle has 2) into one of the clips as shown. The top part to the "T" should be oriented perpendicular to the grove in the cap and fit snugly in the indentation. It will require a little effort to press the axle into the cap (it will snap into place if don't correctly.) If a cap does not seem to fit on an axle, or slips off too easily, try using a different cap on a different axle.

Combine the axles and clips by pressing a "T" shaped end of each axle (each axle has 2) into one of the clips as shown. The top part to the "T" should be oriented perpendicular to the grove in the cap and fit snugly in the indentation. It will require a little effort to press the axle into the cap (it will snap into place if don't correctly.) If a cap does not seem to fit on an axle, or slips off too easily, try using a different cap on a different axle. The caps should secure the entire construction, while allowing the gears to spin freely. If you have trouble, look for tight gears of burs that could be causing issues.

Find the Following Parts

Find the following parts:

  • 4x Wheels
  • 4x Tires

Wrap the Tires Around the Wheels

IMG_2761.JPG

Wrap the tires around the wheels.

Place the Wheels

IMG_2765.JPG

The wheels are designed to fit snuggly onto a clip. Each wheel has an oval indentation with a notch which matches that top profile of the clips. To attach the wheels to the clips:

  • Make sure that the notch in the wheel lines up with the indentation in the clip.
  • Press the wheel firmly onto the clip.

Although the parts are intended to fit snuggly, pressing too hard can damage the parts. Check the parts to make sure that they are free of burs or other bits that may interfere with connections. You can remove these with a file or pliers.
