Technical Overview for Competitive Setups

The 3RACING 48 Pitch Spur Gear 92T, model 3RAC-SG4892, is intended for racers who need repeatable gear engagement in 1/10 on-road classes. The 48 pitch tooth form lets you make small but consistent ratio adjustments to tune acceleration and top speed.

Setup and Mesh Considerations

Fit the spur with careful attention to backlash and axial alignment to minimise uneven tooth loading. Use progressive pinion changes to reach the desired ratio while monitoring mesh under rotational load to detect any binding.

Maintenance for Race Use

Inspect tooth faces for pitting or galling after intensive sessions and keep the mesh area free of grit. Consistent maintenance reduces variance lap to lap and prolongs component service life.

How do I dial in backlash for best lap times

Start with minimal backlash that avoids binding and incrementally increase until you eliminate gear clatter under acceleration. Test lap times after each change to confirm improvements.

What pinion strategy works for circuit tuning

Use one-tooth increments on the pinion to evaluate changes. Record lap times and motor temperature to balance performance gains against thermal limits.

How often should spur and pinion be replaced in race use

Replace if you observe significant tooth wear or irregular engagement. Regular inspection after race meetings helps avoid unexpected failures during competition.
