Tamiya TA01/TA02/DF01 Aluminum Front Gear Box (Bottom) by JAZRIDER JR-TA103-GU  [JR-TA103-GU]

Aluminum front gearbox bottom for Tamiya chassis

This aluminium front gear box bottom replaces the original lower housing used on Tamiya TA01, TA02 and DF01 chassis versions, offering a direct-fit RC-scale spare for maintenance and setup work. Designed as the lower half of the front gearbox assembly, the part provides a firmer mounting surface for the spur and pinion assembly and assists in consistent gear mesh during track use or hobby repairs.

Installation is straightforward for users familiar with Tamiya TA-series assemblies: remove the front gearbox cover screws, separate the transmission halves, transfer internal gears and bearings as required, and fasten the aluminium bottom with the original hardware. Retain original ball bearings and seals unless explicitly replacing them, and check gear mesh after reassembly to avoid premature wear.

Use this part when replacing a damaged plastic lower gearbox, preparing a spare for event support, or when seeking a more rigid base for tuning gear mesh and drivetrain alignment on TA01/TA02/DF01 based models. This component is intended for RC-scale applications only.
