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

Precision aluminium holder for TB-04 spur

This aluminium spur gear holder is supplied as one set and is intended specifically for the TAMIYA TB-04 chassis. Produced by GPM, the component locates and secures the spur gear inside the TB-04 gearbox area to deliver consistent mesh and repeatable alignment during maintenance and setup changes.

Designed with a precision engineering focus, the holder provides a stable interface between the spur gear and the gearbox supports to reduce movement under load. In tuning situations it helps preserve mesh and backlash settings when swapping spur sizes or adjusting drive components, reducing the need for frequent micro-adjustments.

Installation follows standard TB-04 service steps: remove the stock spur retention parts, fit the precision aluminium holder in place, confirm spur-to-pinion mesh and axial clearance, and reassemble the gearbox. This component is intended for RC-scale TB-04 use only; verify fit before final assembly.
