This single-piece 12T aluminium motor gear is offered as a replacement pinion for Kyosho Mini Inferno vehicles and is suitable for tweaking final drive ratios or restoring correct engagement on 1/10 electric models.
Made from an aluminium alloy as noted, the gear aims to provide a consistent tooth profile and steady mesh under normal hobby and club conditions. Before fitting, check shaft compatibility and the pinion mounting method to prevent premature spur or motor gear damage.
Installation guidance: disconnect power, remove or access the motor, slide the 12T pinion into place, set the mesh to a minimal but non-binding clearance, secure the set screw and perform a short low-speed run to confirm smooth operation.
