wheel lock for RIM 55982

[janssnet]

Hi there,

While building a small rc car using a RIM 55982 (18 x 14) I needed a way to lock the wheels to be able to drive it with a motor. Almost started drilling holes ..... and then, after removing the tire, it turned out there is a little notch inside the wheel.

Looks like it is a space for a tiny piece of plastic to slide in, to lock the axle to the wheel. Exactly what I'm looking for!

Have I missed something? Is there a LEGO part that fits this notch and locks the wheel? Or should I make it myself.

Maybe better solution would be to use these rims https://www.bricklink.com/v2/catalog/catalogitem.page?P=55982&idColor=5#T=C&C=86 ? They already come with cross axle hole instead of round pinhole

It to for case, when You need to push out some 1L pin or similar ( I think so)

That's great, thanks for sharing.

That could indeed be the reason for this notch. Thanks.

The reason for the notch is for moulding. The notch allows the pin's ridges to click in...
