Tamiya T3-01 Upgrade Planetary Gears 7075 Alloy - Factory Pro O-AP0005  [FP-O-AP0005]

Planetary gear set made for T3-01 use

This RC-scale planetary gear set is intended for the Tamiya T3-01 chassis, delivered as six pieces and produced from 7075 alloy. It works as a direct swap or performance-minded replacement inside the T3-01 planetary carrier for hobbyists focused on drivetrain reliability without changing the gear ratios.

The kit is specifically for the Tamiya T3-01 configuration as shown in the product title. The 7075 alloy identifies the construction material and offers a useful compromise between wear resistance and weight for scale running. Fit these gears where steady mesh engagement and consistent wear behaviour are priorities in everyday RC use.

Prior to fitting the new planets, inspect the carrier and sun gear for signs of wear, degrease the assembly, and check bearings. Maintain original mesh and backlash tolerances during installation; avoid forcing components and spin the drivetrain to confirm smooth rotation. Use a light gear grease suitable for metal gears to keep operation quiet and long lasting.
