FAQs
What does '18T' and '0.8mod' mean?
'18T' refers to the number of teeth on the pinion gear, which is 18. '0.8mod' refers to the module pitch of the gear teeth, indicating the size and spacing of the teeth for proper meshing with a compatible spur gear.
How do I know if this pinion gear fits my ARRMA car?
You must consult your specific ARRMA vehicle's user manual. It will list compatible part numbers and provide exploded views of the drivetrain to confirm fitment. You can also check the official ARRMA-RC website.
Can I use this pinion gear with any spur gear?
No, this pinion gear is specifically a 0.8 module pitch. It must be used with a spur gear that also has a 0.8 module pitch to ensure proper meshing and prevent damage.
What is the benefit of using a genuine ARRMA part?
Genuine ARRMA parts are manufactured to precise specifications, ensuring optimal performance, durability, and compatibility with your ARRMA vehicle. Using non-genuine parts may compromise performance and reliability.
How often should I check my pinion gear?
It is recommended to inspect your pinion gear regularly, especially after hard driving sessions, for signs of wear, damage, or debris. Consistent checks help maintain optimal performance and prevent unexpected failures.
What happens if the gear mesh is too tight?
If the gear mesh is too tight, it can cause excessive friction, leading to increased heat, premature wear on both the pinion and spur gears, and potentially damage to the motor or drivetrain components.
What happens if the gear mesh is too loose?
If the gear mesh is too loose, it can result in noisy operation, gear stripping, reduced efficiency, and potential damage as the teeth impact each other without proper support.
Troubleshooting
Gear stripping or excessive wear
Check for proper gear meshing (lash). Ensure the pinion grub screw is tight and the pinion is fully seated on the motor shaft. Inspect spur gear for damage. Replace both if necessary. Ensure the pinion is the correct part for the vehicle.
Excessive noise during operation
Verify correct gear meshing. Debris or dirt caught between gears can cause noise; clean the gear area thoroughly. Ensure the pinion is correctly aligned with the spur gear.
Vehicle lacks acceleration or top speed
Inspect pinion and spur gears for wear. A worn gear can cause inefficient power transfer. Ensure the correct gear ratio is being used for the desired performance. Check motor mount security.

Setup, Compatibility & Care
Compatibility: To ensure this 18T 0.8 module pinion gear is compatible with your ARRMA vehicle, always refer to your specific model's user manual. The manual will contain detailed information on recommended spare parts and exploded views of the drivetrain. You can also find compatibility information on the official ARRMA-RC website.
Setup: Installation requires disassembling the gear cover to access the motor and spur gear. The pinion gear needs to be securely mounted to the motor shaft, typically with a grub screw. Ensure the pinion and spur gears mesh correctly; there should be a slight amount of play (lash) between the teeth to prevent binding and allow for thermal expansion. Overtightening the grub screw or improper meshing can lead to damage.
Care: Regularly inspect the pinion gear for signs of wear, damage, or stripped teeth. Clean the gear area to remove dirt and debris that can accelerate wear. If the gear becomes excessively worn or damaged, it should be replaced immediately to prevent damage to the spur gear or other drivetrain components. Always use genuine ARRMA replacement parts.
