Technical Overview of the 3Racing T37 Pulley

The 3Racing Aluminum Differential Pulley Gear T37, model number 3RAC-3PY/37, is engineered for competitive setups where consistent power delivery and component life are critical. The design focuses on dimensional stability and repeatable performance under race conditions.

Racing-Focused Performance Characteristics

Manufactured to support precise drivetrain behaviour, the T37 pulley helps maintain engagement geometry under load. This ensures predictable torque transmission and reduces the frequency of minor adjustments during race meets.

Workshop Notes for Tuners

  • Material: High-grade aluminum for increased durability
  • Compatibility: Intended for common RC configurations to allow easy swap-ins
  • Functionality: Optimises power transfer and reduces wear on mating components

How does the 3RAC-3PY/37 affect adjustable setups?

The pulley maintains consistent geometry so tuning for backlash and belt tension becomes more repeatable. That stability helps when dialling in suspension and drivetrain balance for racing conditions.

Are any machining or balancing steps required?

Out of the box the 3RAC-3PY/37 should be ready to fit, but precision builds may benefit from a quick static balance check and verification of concentricity on the shaft to eliminate vibration at high RPM.

Installation torque and maintenance recommendations?

Torque set screws to manufacturer guidance, confirm axial alignment, and inspect interface surfaces regularly. Replace if you notice fretting or profile wear to protect adjacent drivetrain parts.
