TAMIYA TB-04 Aluminium Spur Gear Holder by GPM TB4315  [TB4315]

Aluminium Spur Gear Holder for TB-04

This aluminium spur gear holder is an RC-scale replacement part produced by GPM for use on the TAMIYA TB-04 chassis, supplied as 1 set. It is a mounting component intended to position and secure the spur gear within the TB-04 gearbox area, keeping the gear mesh consistent under routine use and during setup changes.

Designed as an aftermarket aluminium part, the holder focuses on providing a stable interface between the spur gear and the surrounding gearbox supports. In practical tuning work it helps maintain consistent mesh and lash settings when swapping spur gears or adjusting drive components, and it reduces the need for repeated alignment during short maintenance cycles.

Installation is straightforward for technicians familiar with TB-04 maintenance: remove the existing spur gear retaining elements, fit the aluminium holder in place of the stock item, confirm spur-to-pinion mesh and axial clearance, then reassemble the gearbox. The component is intended for RC-scale TB-04 use only and should be checked for fit before final assembly.
