4x LEGO Technic Wedge Belt Wheel (Pulley) + Tire 4185c01 Light Old Grey Lot 1336

About this deal

A used lot of four LEGO Technic Wedge Belt Wheels (Pulleys) complete with their matching rubber tires, all in Light Old Grey. Part number 4185c01 combines the wedge belt wheel pulley (part 4185) with a black wedge belt wheel tire, and the assembly has been in the LEGO range since 1983. The part sits within the Wheels and Tyres category and has appeared across hundreds of Technic sets over the decades. These pulleys are a staple component for LEGO Technic builders. The wheel pairs with the dedicated wedge belt wheel tyre (part 2815) , and the V-shaped profile allows rubber bands or dedicated belts to be run between two or more pulleys to transfer rotational motion. They are well suited to motorised vehicles, functional machines, and robotic models. Buying four together means you have enough for a complete two-pulley belt-drive system with spares, making this lot ideal for parts-packers or anyone restoring a vintage Technic set.
