  • Product typeToys - Replacement Parts
  • Pack of 10 gears keeps spares on hand for multiple repairs

  • 8-tooth design meshes smoothly with matching pinions
  • White plastic construction resists corrosion in humid conditions
  • Compact 4.5 mm outer diameter suits tight model spaces

White Plastic 8-Tooth Gears

This pack contains ten white plastic gears designed for DIY RC models and mechanical projects. Each gear has eight teeth and fits a 2mm shaft diameter. The compact size of 4.5 by 5mm makes them suitable for tight spaces in small-scale builds. They are sold as new replacement parts for hobbyists and makers.

Simple Press-Fit Installation

Installation is a straightforward press-fit onto a 2mm shaft, requiring no specialised tools. The lightweight plastic construction keeps the total pack weight at just 3g. A common issue is stripping the small 8-tooth profile if excessive torque is applied during operation. Ensure the shaft diameter matches the .08 inch specification exactly to prevent wobble or slippage.

Check Shaft Diameter and Space

Before ordering, verify that your model uses a 2mm shaft and that the gear housing accommodates a 4.5mm outer diameter. The .18 inch thickness must also fit within your assembly's gear train spacing. These gears are not suited for high-load drivetrains or metal gearbox upgrades. Buyers needing larger tooth counts or metal durability should look elsewhere.
