Scorpion SPHK-2213MSK 4mm Motor Shaft (3.17mm Output) for HK-2213 series  [SPHK-2213MSK]

Service shaft for HK-2213 motors

This shaft kit is produced to fit the Scorpion HK-2213 series outrunner motors. It supplies a 4mm main shaft with a 3.17mm output end that aligns with the original output geometry of HK-2213 housings and pinion mounts. The part is intended as a direct replacement to recover axial alignment and rotational support when the original shaft is compromised.

Fitting usually involves removing the motor endbell, pulling the rotor assembly, and replacing the damaged shaft while checking bearing seats and internal clearances. After installation, verify that the rotor spins freely and that endplay is within acceptable limits before reinstalling the motor. The kit contains the shaft component only; bearings and other wear items should be inspected and replaced if needed.

Choose this shaft when performing standard motor maintenance, repairing an HK-2213 outrunner after impact or wear, or preparing a motor for tuning and balance adjustments. This item is for model-scale RC motors and not for full-size applications.
