TB-04 Spur Gear Mount Aluminium Upgrade TB4315 by GPM  [TB4315]

Aluminium spur gear mount for TB-04

This aluminium spur gear mount is supplied as a single set and is intended for use on the TAMIYA TB-04 touring chassis. Manufactured by GPM, the part locates and secures the spur within the TB-04 gearbox area to maintain correct mesh and alignment under normal use and when making setup changes.

Built as an aftermarket aluminium upgrade, the mount provides a reliable interface between the spur and surrounding gearbox supports. In day-to-day tuning it helps the mesh and lash settings remain stable when changing spur sizes or adjusting drive components, so you spend less time realigning parts.

Installation follows familiar TB-04 service steps: remove the stock spur retaining items, fit the aluminium mount in place, verify spur-to-pinion engagement and axial clearance, and reassemble the box. Intended for RC-scale TB-04 gearboxes only; test the fit before completing reassembly.
