Mini 4WD STEM Spare Gear Pack Tamiya 70269  [70269]

Spare gear pack for educational Mini 4WD

The Tamiya 70269 Universal Gear Set is supplied as a replacement gear pack intended for the STEM Series construction range. The notes below assume you are familiar with Tamiya construction parts and simple gear-driven drivetrains commonly used in educational Mini 4WD projects.

Practical uses include replacing damaged gears in school workshops, maintaining static or working display models, and backing up prototype assemblies where interchangeability is helpful. This kit is intended as a parts replacement rather than a racing performance mod.

Fitment tips: check tooth engagement and lateral play prior to finalising assembly, align driving and driven shafts to prevent binding, and examine gears for any broken or misshapen teeth. If you choose to lubricate, apply a small amount of hobby-grade lubricant to the contacting areas only.

Fit advice: confirm the dimensional fit against your construction frame. This set is aimed at the STEM Series construction platform and comparable Tamiya educational kits; it is not specified for use on dedicated high-speed Mini 4WD racing chassis.
