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

Replacement shaft for HK-2213 outrunners

This replacement shaft kit is made specifically for the Scorpion HK-2213 series outrunner motor family. The kit provides 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 component serves as a direct service item to restore axial alignment and rotational support when the original shaft is worn or damaged.

Typical installation requires removing the motor endbell, extracting the rotor assembly, and swapping the damaged shaft while checking bearing seats and clearances. After fitment, confirm smooth rotation and correct endplay before reinstalling the motor into its mount. The kit covers the shaft only; inspect bearings and other wear items during service and replace as necessary.

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