Frequently Asked Questions

• What is a pinion gear and why do I need to replace it? — A pinion gear is the small gear mounted on your motor shaft that meshes with the larger spur gear to transfer power to your wheels. Over time, pinion gears can wear out from constant engagement, become damaged from crashes, or need replacement when experimenting with different gear ratios to optimise your RC car's performance. This 13-tooth pinion from Team Associated is the direct replacement for MT12 Monster Truck owners.
• Will this pinion gear fit my MT12 Monster Truck? — Yes, this is the OEM (original equipment manufacturer) pinion gear designed specifically for the Team Associated MT12 Monster Truck platform. The part number AS41157 uniquely identifies this component as compatible with the MT12's drivetrain, and the 2.25 shaft diameter and 0.6 module specification ensure perfect fit and mesh with your existing spur gear.
• What does the Mod 0.6 specification mean? — Mod 0.6 refers to the module rating of the gear tooth pitch. This specification must match your spur gear for proper mesh alignment and smooth power delivery. The 0.6 module is standard for the MT12 Monster Truck drivetrain, so any Mod 0.6 compatible spur gear will work perfectly with this pinion.
• How do different tooth counts affect my RC monster truck's performance? — Pinion tooth count directly influences your vehicle's gear ratio. A lower tooth count (like this 13T) typically provides stronger acceleration and lower top speed, while a higher tooth count increases top speed but reduces acceleration. Experimenting with different tooth counts allows you to fine-tune your MT12 Monster Truck for different track layouts and racing conditions.
• Is this suitable for both racing and casual bashing? — Absolutely. Whether you're competing in local RC car UK races or enjoying casual weekend bashing, this Team Associated pinion gear is engineered for reliable performance across all driving styles. The precision manufacturing ensures durability whether you're pushing for lap records or simply having fun on outdoor terrain.
• Do I need any special tools to install this pinion gear? — Installation typically requires removing the motor from your MT12 and using a pinion puller tool or small hex key to remove the existing pinion. While specific installation instructions aren't detailed in the product information, Team Associated components are designed for straightforward installation by anyone with basic RC car maintenance knowledge.
