This compact puller is an accessory for electric RC models that use small 22mm propeller adaptors on motor shafts. It is intended to help detach adaptor collars and press-fit prop parts from the motor shaft without stressing the shaft or surrounding components.
Design and role: the tool concentrates force evenly around a 22mm adaptor interface, allowing safe extraction of propeller adaptors and hub-type fittings during maintenance, motor swaps, or when changing propeller setups for tuning.
Installation and use notes: position the puller concentric to the adaptor, apply steady axial force, and avoid lateral levering that can damage wave washers or bearings. If a propeller hub resists removal, inspect the shaft nut and set screws first and back off any threadlocker before applying the puller.
Tuning and workshop guidance: removing adaptors cleanly keeps motor bearings and shaft ends free from burrs and contamination, which supports consistent motor alignment under different prop loads. Use careful, incremental force and check for any retained clips or spacers before full extraction.
