This 17T aluminium motor gear is provided as an aftermarket replacement compatible with Kyosho Mini-Z AWD platforms and is intended to seat on MR-03 AWD motor shafts using the original pinion interface. The item is supplied as a single gear and includes the screw required for mounting.
Manufactured from aluminium alloy, the gear is intended for routine service, preventative maintenance and basic tuning swaps. It restores worn mesh and acts as a reliable spare for hobbyists preparing a Mini-Z AWD for regular running.
Fitment procedure: access the motor per MR-03 AWD service instructions, remove the existing pinion, install the 17T alloy gear onto the motor shaft, secure with the provided screw, and verify correct mesh and smooth rotation prior to reassembling the chassis and body. Only standard Mini-Z hex drivers are typically required.
