Precision Pulley for Competitive Setups

The 3RACING Aluminium Differential Pulley Gear T32, 3RAC-3PY/32, is intended for racers focused on drivetrain consistency and fine tuning. Machined aluminium reduces rotating mass while maintaining the dimensional stability required for repeatable gear mesh.

Integration and Tuning Considerations

This pulley interfaces with common 1/10 scale differential outputs; accurate alignment and correct shim practice will preserve bearing life and minimise lash. Use measured torque on fasteners to avoid distortion of mating components.

Material and Performance Trade Offs

Aluminium offers a predictable stiffness-to-weight ratio and resists corrosion, which helps when optimising handling and transient response. It is well suited for drivers tuning for predictable power transfer under race conditions.

What checks should I make before installing the pulley?

Verify bore diameter and keying, confirm alignment with the differential spline, and ensure there is no axial play that could affect gear timing.

How can I optimise gear mesh with this aluminium pulley?

Adjust shims incrementally while checking for smooth rotation under load; minimal yet consistent clearance yields the best balance of noise and durability.

Any recommended maintenance for race use?

Inspect for impact damage after incidents, clean contact surfaces, and monitor fastener torque between events to maintain consistent performance.
