FAQs
What does '17T 48DP' mean?
'17T' refers to 17 teeth, and '48DP' refers to the module or pitch of the gear teeth (48 diametral pitch), which dictates how the gear meshes with the spur gear.
How do I know if this pinion gear is compatible with my ARRMA vehicle?
Consult your ARRMA vehicle's user manual or visit the Arrma-RC website. Look for exploded views or parts lists to confirm the correct part number for your specific model.
Can I use this gear on a non-ARRMA RC car?
While the 48DP pitch is common, compatibility depends on the motor shaft size and the spur gear's pitch on the other vehicle. It's best to use genuine ARRMA parts for ARRMA vehicles to ensure correct fitment and performance.
What is the benefit of using a metal pinion gear?
Metal pinion gears, like this one, offer superior durability and resistance to wear compared to plastic or composite gears, making them suitable for high-performance applications.
How often should I check or replace my pinion gear?
Regular inspection is recommended, especially after hard use. Replace the pinion gear if you notice significant wear, chipped teeth, or damage. For routine maintenance, check every few runs.
Does this pinion gear come with a set screw?
Typically, pinion gears are sold separately from set screws or mounting hardware. Please check the product packaging or description for included accessories. If not included, you may need to purchase one separately, ensuring it matches the motor shaft size.
Troubleshooting
Gear stripping or excessive wear
Check motor alignment and ensure proper gear mesh. Verify that the pinion is the correct specification for the vehicle and intended use. Inspect for debris between gear teeth.
Noisy drivetrain
Inspect gear mesh; it may be too tight or too loose. Ensure the pinion is securely fastened to the motor shaft. Check for bent or damaged gear teeth.
Pinion gear loose on motor shaft
Ensure the set screw (if applicable) is tightened securely. If the motor shaft or pinion bore is damaged, the motor shaft or pinion may need replacement.

Setup, Compatibility & Care
Compatibility: This pinion gear is specifically designed for ARRMA vehicles. Always refer to your vehicle's user manual or the official Arrma-RC website for exploded views and part number confirmation to ensure this 17T 48DP pinion gear is the correct replacement or upgrade for your model. Using incorrect parts can lead to drivetrain damage.
Setup: Installation typically involves removing the motor mount screws, sliding the pinion gear onto the motor shaft, and securing it with the motor screws. Ensure the pinion gear meshes correctly with the spur gear, with minimal play but without binding. The correct gear mesh is critical for performance and component longevity. Refer to your vehicle's manual for specific motor mounting and gear mesh adjustment procedures.
Care: To maintain optimal performance, regularly inspect the pinion and spur gears for wear, debris, or damage. Clean the gears and surrounding drivetrain components with a soft brush or compressed air to remove dirt and grit. Lubrication of the gear teeth is generally not recommended for metal pinion gears; keep them clean and dry. Replace the pinion gear if significant wear or damage is observed.
