Scorpion SPHK-2213MSK motor shaft kit for HK-2213 series outrunner motors, 4mm shaft with 3.17mm output end  [SPHK-2213MSK]

Motor shaft kit for HK-2213 series

This replacement shaft kit is designed specifically for the Scorpion HK-2213 series outrunner motor family. The listing denotes a 4mm main shaft with a 3.17mm output end to match the original output geometry used on HK-2213 housings and pinion interfaces. The part functions as a direct service item for restoring axial alignment and restoring rotational support where the original shaft has worn or been damaged.

Installation generally involves removing the motor endbell, extracting the rotor assembly, and replacing the damaged shaft while inspecting bearing seats and clearances. After fitment, verify smooth rotation and correct endplay before reassembling the motor into its mount. The kit addresses the shaft component only; inspect bearings and other wear items during service and replace as needed.

Use this shaft kit when performing routine motor maintenance, rebuilding an HK-2213 outrunner after impact or wear, or when preparing a motor for tuning and balance work. The component is for model-scale RC motors and is not intended for full-size vehicle use.
