Motor Pinion Gear Puller Tool for RC Helicopter & Vehicle
The Motor Pinion Gear Puller is a professional-grade, compact metal tool designed to safely and efficiently remove pinion gears, bearings, and inner rings from small motors used in RC helicopters, RC cars, and other remote-control vehicle models. With five interchangeable pins covering a range of shaft diameters, this versatile kit handles a wide variety of gear sizes — all in one tidy set.
Made in Mainland China.
Key Features
- 5 Interchangeable Pins — Includes pins in five sizes: 0.9mm (Cylindrical), 1.75mm (Semicircular), 1.75mm (Cylindrical), 1.9mm (Cylindrical), and 2.8mm (Semicircular), covering a broad range of motor shaft diameters.
- Metal Construction — Built from durable, wear-resistant metal for long-lasting reliability and stable performance across repeated use.
- Lightweight & Compact — Easy to carry and store; perfect for hobbyists working at the bench or in the field.
- Wide Compatibility — Suitable for RC models, car inner rings, bearings, and other dense small components.
- Max Gear Capacity — Handles gears with a maximum outer diameter of 11mm and tooth height of 12mm.
- No Battery Required — Fully manual, no power source needed.
- Recommended Age: 14 years and above.
How to Use
- Select the correct pin to match your motor shaft diameter. Using a pin that is too small for the shaft may break the ejector pin. If the gear has been glued, gently heat it first to soften the adhesive before proceeding.
- Attach your chosen ejector pin to the rotating rod and tighten the screw — do not over-tighten flat-tip pins.
- Insert the rotating rod assembly into the gear puller bracket.
- Attach the gear puller traveling plate.
- Clip the motor into the traveling plate and align the motor shaft with the ejector pin.
- Rotate the lever clockwise in a smooth, even motion to extract the pinion gear.

Frequently Asked Questions
Q: What sizes of motor shafts is this pinion gear puller compatible with?
A: This motor pinion gear puller includes five pins — 0.9mm (Cylindrical), 1.75mm (Semicircular), 1.75mm (Cylindrical), 1.9mm (Cylindrical), and 2.8mm (Semicircular) — making it compatible with a wide range of small RC motor shaft diameters. Always select the pin that matches your specific shaft diameter to avoid damaging the ejector pin.
Q: Can I use this gear puller on glued pinion gears?
A: Yes, but you must gently heat the glued gear first to soften the adhesive before attempting extraction. Trying to pull a firmly glued gear without pre-heating may damage the tool or the motor.
Q: What is the maximum gear size this tool can handle?
A: The motor pinion gear puller can extract gears with a maximum outer diameter of 11mm and a maximum tooth height of 12mm, covering most standard small RC vehicle and helicopter motors.
Q: Is this tool suitable for beginners working on RC models?
A: Absolutely. The tool is designed to be straightforward to assemble and use. It is recommended for users aged 14 and above. Simply follow the step-by-step usage guide included above, and you'll be removing pinion gears with confidence in no time.
