3. Package Contents
The FMS 1/18 RC Car Plastic Gear Set includes all necessary plastic gears for a complete replacement or upgrade. The set is designed to be a full, ready-to-install kit, providing a convenient solution for maintaining your RC vehicle's drivetrain.
4. Setup and Installation
This gear set is engineered for precision and ease of installation. While designed for straightforward replacement, basic mechanical knowledge of RC car assembly is recommended. Always refer to your specific RC car model's service manual for detailed disassembly and reassembly instructions.
- Preparation: Ensure your RC car is powered off and the battery is disconnected. Gather necessary tools such as small screwdrivers, pliers, and a clean work surface.
- Accessing Gears: Carefully disassemble the relevant sections of your RC car to gain access to the existing gear assembly. This typically involves removing body panels, transmission covers, or axle housings.
- Removal of Old Gears: Once accessible, carefully remove the worn or damaged gears. Note the orientation and placement of each gear for correct reinstallation.
- Installation of New Gears: Install the new FMS plastic gears into their respective positions. Ensure all gears mesh smoothly without binding. Apply a small amount of appropriate RC gear grease (not included) if recommended by your vehicle's manual.
- Reassembly: Reassemble your RC car by reversing the disassembly steps. Ensure all screws are tightened securely but do not overtighten, as this can strip plastic threads.
- Functionality Check: After reassembly, manually rotate the wheels and drivetrain components to confirm smooth operation before reconnecting the battery and powering on the vehicle.

5. Operating Considerations
After installing the new plastic gear set, operate your RC car responsibly. While the gears are designed for durability, aggressive driving or impacts can still cause damage. Regular inspection of the drivetrain components is recommended to ensure continued smooth operation.
6. Maintenance
Proper maintenance extends the lifespan of your gear set and RC car. Follow these guidelines:
- Regular Inspection: Periodically inspect the gears for signs of wear, cracks, or stripped teeth. Replace any damaged gears promptly to prevent further damage to other drivetrain components.
- Cleaning: Keep the gear area free from dirt, dust, and debris, which can accelerate wear. Use a soft brush or compressed air for cleaning.
- Lubrication: If your RC car's manual recommends it, apply a small amount of appropriate RC gear grease to the gear teeth to reduce friction and wear. Avoid over-lubrication, which can attract dirt.
- Storage: Store your RC car in a clean, dry environment when not in use.
7. Troubleshooting
If you experience issues after installing the gear set, consider the following:
- Gears Not Meshing Smoothly: Ensure all gears are correctly seated and aligned. Check for any foreign objects obstructing the gear train.
- Unusual Noises: Grinding or clicking noises often indicate improper gear mesh, damaged teeth, or the presence of debris. Disassemble and inspect the gears.
- Gears Breaking Easily: While these are replacement parts, excessive force or impacts can cause breakage. Review your driving style and ensure the gears are installed correctly without binding. If issues persist despite careful use and correct installation, contact customer support.
