This 17-tooth aluminium motor gear is supplied as an aftermarket service replacement for Kyosho Mini-Z AWD platforms and is intended to fit MR-03 AWD motor assemblies that use the original pinion interface. The pack includes the single alloy pinion and the screw required to secure it to the motor shaft.
Produced in aluminium alloy for consistent dimensions, the pinion is aimed at routine maintenance and tuning tasks. It restores worn gear engagement and provides a dependable spare when preparing a Mini-Z AWD for regular running or practice sessions.
Installation steps: remove the motor following MR-03 AWD service guidance, remove the old pinion, fit the 17T alloy pinion onto the shaft, tighten with the supplied screw, then confirm correct mesh and unhindered rotation before putting the model back together. No specialist equipment beyond standard Mini-Z hex drivers is necessary.
