Scorpion SPHK-2206MSK25 Outrunner Motor Shaft Kit 4mm Shaft / 2.5mm Output End  [SPHK-2206MSK25]

Outrunner motor shaft replacement

This is a replacement shaft kit for Scorpion HK-2206 series outrunner motors intended for RC-scale use only. The kit provides the specific shaft profile needed to restore a HK-2206 motor after shaft wear or damage, keeping the motor aligned with its bearings and pinion gear. Use this part when the original shaft shows runout, scoring, or when a reliable output end fit is required for continued model operation.

Installation notes: remove the motor bell and inspect bearings and endplay before fitting the replacement shaft, ensure the shaft slides smoothly into the rotor and that the output end seats correctly with the pinion or coupling. After reassembly, check free spin and motor runout at low speed before full operation. The part supports routine motor maintenance and tuning, enabling precise alignment during rebuilds or upgrades.
