Scorpion SPHK-2213MSK HK-2213 Outrunner Shaft 4mm x 3.17mm  [SPHK-2213MSK]

HK-2213 shaft replacement details

This shaft kit is intended for the Scorpion HK-2213 series of outrunner motors. It supplies a 4mm main shaft with a 3.17mm output end that matches the original output geometry used in HK-2213 housings and pinion interfaces. The item functions as a service replacement to restore axial alignment and rotational support when the original shaft shows wear or damage.

To fit the shaft, remove the motor endbell, extract the rotor assembly, and replace the damaged shaft while checking bearing seats and internal clearances. After fitting, confirm smooth rotation and correct endplay before reinstalling the motor. The kit is for the shaft only; inspect and replace bearings and other worn items as required during service.

Fit this shaft when carrying out regular motor maintenance, rebuilding an HK-2213 outrunner after impact or wear, or when preparing a motor for tuning and balance adjustments. The component is intended for model-scale RC motors and not for full-size vehicle use.
