This aluminium front gear box bottom replaces the stock plastic lower housing on Tamiya TA01, TA02 and DF01 chassis variants, providing a direct-fit spare for servicing and setup. As the lower half of the gearbox it strengthens the mounting for the spur and pinion assembly and supports consistent gear mesh during use.
Fitting is carried out in the usual TA-series manner: remove cover screws, split the gearbox halves, transfer gears and bearings if needed, then secure the aluminium lower with the original hardware. Retain original bearings and seals unless they require replacement, and verify gear mesh after assembly.
Suitable when replacing a damaged lower housing, keeping a spare for event support, or when a more rigid base is required to refine gear backlash and drivetrain alignment on TA01/TA02/DF01 setups. For RC-scale applications only.
