Technical overview: aluminium alignment adaptor

This aluminium gear adaptor is intended as a dedicated alignment interface for the Tamiya TB-02 chassis, locating the motor pinion relative to the TB-02 spur to provide repeatable mesh during assembly and component changes.

Functionally the adaptor acts as a rigid spacer to improve seating and reduce lateral play in the drive stack. It is not intended to alter gear ratios; instead it aids consistent pinion engagement and steady positioning under drive load.

Workshop notes: verify physical clearance within the TB-02 gearbox area and confirm gear mesh visually after installation. Use measured, incremental motor adjustments or shims to achieve the desired tooth contact and document placement for repeatable test setups.

How should I verify fitment on the TB-02?

Dry-fit the adaptor, check clearances around the gearbox, then assemble the motor and pinion to inspect mesh under slow rotation. Confirm there is no binding across the engagement arc.

Can it be used to document repeatable motor positioning?

Yes. Once the optimal motor position is set, record spacer and shim details so the same placement can be replicated during motor swaps or setup comparisons.

Does the adaptor require additional reinforcement?

In typical TB-02 configurations the adaptor provides sufficient alignment support. If your build has custom gearbox mods, check mounting integrity and consider supplementary support as needed.
