Technical Notes for 3Racing 48P Spur Gear

This 48 pitch spur with 73 teeth is intended for precise gear ratio adjustments in competitive builds. It provides repeatable tooth engagement and allows fine tuning of acceleration and top speed when paired with suitable pinion choices.

How should I set mesh for consistent performance?

Aim for a minimal uniform gap across the tooth face, verify by rotating the drivetrain by hand, then tighten components and recheck under slight motor load to ensure stability.

What pinion pairing is recommended for track tuning?

Select pinion teeth to achieve the target ratio for your course; smaller pinions increase torque and acceleration, larger pinions favour higher top speed, so test incrementally to find the best compromise.

How do I monitor gear wear during competition?

Regularly inspect for tooth rounding, surface irregularities and noise under load; replace the spur at the first sign of progressive wear to protect pinion and gearbox components.

Any adjustments for high torque setups?

For higher torque motors consider verifying hub clamping and backing plates, confirm gear alignment, and monitor temperatures and wear as torque increases load on the gear train.
