Technical overview for 3Racing 64 Pitch Spur Gear 89T

The 3Racing 64 Pitch Spur Gear 89T Ver.2, model 3RAC-SG6489/V2, is intended for racers and tuners who require repeatable drivetrain characteristics. It offers a stable 89-tooth platform for fine tuning final drive and managing torque transmission.

Setup and tooth accuracy

Accurate tooth form and consistent pitch reduce variations in mesh, allowing precise pinion matching and predictable load transfer. This stability is valuable when iterating gearing for lap time improvements.

Service and longevity considerations

When used with correct mesh settings and appropriate lubrication, the spur maintains dimensional integrity over many runs. Regular inspection of tooth faces will help identify wear patterns relevant to setup refinement.

Tuning guidance

Use this spur to explore narrower gearing steps or to restore consistency after drivetrain changes. Pair it with compatible 64 pitch pinions and verify alignment under light load before competitive sessions.

What pinion considerations should I account for?

Select a 64 pitch pinion with appropriate tooth count to achieve your target final drive. Check axial alignment to avoid side loading and uneven wear.

How do I monitor wear for setup decisions?

Inspect for flank rounding, inconsistent contact patterns, or increased backlash; record changes to correlate with setup adjustments and material choices.

Any tips for quieter, more efficient operation?

Set a consistent, minimal mesh clearance, balance the drivetrain, and use a suitable lubricant to reduce friction and noise without masking contact irregularities.
