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

Planetary gear set built for T3-01

This is an RC-scale planetary gear set intended for the Tamiya T3-01 chassis, supplied as a six-piece kit manufactured from 7075 alloy. It is offered as a direct replacement or as an upgrade within the T3-01 planetary carrier for modellers seeking improved drivetrain consistency without changing gear ratios.

The fitment is specific to the Tamiya T3-01 configuration referenced in the product title. The 7075 alloy identifies the construction material and provides a trade-off between wear resistance and weight for scale driving. These gears are selected to maintain predictable mesh engagement and wear behaviour under standard RC operating conditions.

When refitting planetary gears, inspect the planetary carrier and sun gear for damage, strip and clean old grease, and verify bearing condition before installing the new pieces. Maintain original mesh and backlash tolerances; avoid forcing components and rotate the assembly to confirm free movement post-install. Use a light gear grease suitable for metal gears to ensure quiet, reliable running over time.
