This 1pc 12T aluminium-alloy motor gear is a replacement pinion for Kyosho Mini Inferno cars and can be used to restore correct engagement or alter final drive behaviour on 1/10 electric platforms.
Specified as an aluminium alloy item, the pinion is aimed at maintaining a uniform tooth profile and consistent mesh under ordinary hobby and track conditions. Prior to installation, confirm shaft diameter and pinion mounting type to minimise risk of premature wear to the spur or motor gear.
Simple installation: switch off power, remove or access the motor to change the pinion, fit the 12T gear on the shaft, set a minimal non-binding mesh gap, secure the set screw and carry out a low-speed verification run to ensure smooth engagement.
