Return to the BUILD

“In this issue, the center wheel on Optimus Prime’s right leg is assembled and fitted.”

The assembly steps in this issue will be nearly identical to those in Issue 15, where we built the first wheel.



Materials: The Tire and Wheel Cover are PVC rubber, and the other parts are plastic.

The Right Leg (7)

Step 17-1

Fit the Inner Rim to the Outer Rim, aligning the screw holes as shown.

With my model, these parts were already fitted together, so you might need to check if yours are the same:

Secure the two Rims together with four (4) silver IP screws:

Step 17-2

Fit this Rim assembly inside the Tire by stretching it around the edge.

As with the first Tire, I recommend soaking this Tire in a bowl of hot water for a few minutes to soften it:

Take care when removing the Tire to prevent any burns, dry the Tire off, and then it should easily slip onto the Rim as shown:

Step 17-3

Firmly press the four pins of the Hubcap into the matching holes of the Outer Rim, as shown:

Step 17-4

Fit the Wheel Cover over the side of the Tire with the Hubcap, as shown. There are six tabs around inside the Wheel Cover that should slide into the matching grooves around the outer edge of the Tire:

If you find your Wheel Cover is not perfectly round, you can also soften it by soaking it for a few minutes in hot water, just like the Tire:

Then, it should easily slide over the Tire and hold the proper shape. The silver bars of the Wheel Cover should rest on the Outer Rim, as shown:

Step 17-5

Retrieve your Right Leg assembly from the previous issue. Snap the socket of the Inner Rim onto the Right Center Wheel Ball Joint (10E) at this location, as shown.

This Ball Joint gives this Tire the ability to be adjusted into various positions, as desired:


Another issue, another wheel. Not much to say with this one!
