Frequently Asked Questions

• What vehicle is this pinion gear designed for? — This 16-tooth pinion gear with 0.5 module tooth profile and 2.3mm shaft bore is designed specifically for the Team Associated RC28R and other compatible models that specify 0.5 mod gearing with a 2.3mm motor shaft. Always verify your vehicle's specifications before purchasing to ensure compatibility.
• Why would I need to replace my pinion gear? — Pinion gears wear over time with regular use, especially in competitive racing where drivetrain components experience constant stress. Worn gears produce noise, reduce efficiency and can damage other drivetrain components. Replacing a worn pinion gear restores smooth operation and prevents further damage to your differential system. Additionally, some drivers prefer to keep spare gears on hand for quick track-side replacements.
• How do I know if this is the correct gear for my RC car? — Check your vehicle's manual or specifications to confirm it uses 0.5 module gearing with a 2.3mm motor shaft bore. The RC28R platform is the primary application for this component, but compatibility may extend to other Team Associated models with matching specifications. When in doubt, contact RC Model Shop's expert team for confirmation before ordering.
• Is this a genuine Team Associated part? — Yes, this is an authentic OEM replacement part from Team Associated, manufactured to the same specifications as the original equipment. Genuine parts ensure perfect compatibility and performance, whereas aftermarket alternatives may have tolerance variations that affect handling and durability.
• What tools do I need to install this pinion gear? — Installation typically requires basic RC tools including hex keys and possibly a gear puller, depending on your motor setup. Detailed installation instructions are available in the RC28R manual or on the Team Associated website. If you're unfamiliar with drivetrain maintenance, RC Model Shop's team is happy to provide guidance.
• Can I use this gear with other RC car models? — This pinion gear is engineered for vehicles that specify 0.5 module gearing with a 2.3mm motor shaft. Using it in incompatible setups will result in poor meshing, noise and potential damage. Always confirm compatibility before installation.
• How often should I replace my pinion gear? — Replacement frequency depends on how often you use your RC car UK vehicle and under what conditions. Competitive racers may replace gears every few months, while casual bashers might go much longer. Inspect your gears regularly for signs of wear, chipping or teeth damage and replace when necessary.
