Technical Notes on the 3RACING Aluminum Differential Pulley Gear T33

The 3RACING Aluminum Differential Pulley Gear T33, designation 3RAC-3PY/33, is engineered to reduce rotational inertia while maintaining service durability under race conditions. Its aluminium body offers consistent dimensional stability that benefits tuning repeatability and setup precision.

Engineering Advantages

Aluminium provides a stiff, wear resistant surface that holds gear profiles with minimal deformation. This translates to stable engagement and more predictable power transfer when tuning motor and differential settings for racing applications.

Installation and Setup Considerations

Confirm spline and bore compatibility, check axial clearance, and assess whether additional shimming or bearing support is required to keep backlash and mesh within desired tolerances. Proper lubrication and torque settings are important to preserve preload and prevent fretting.

What measurements are critical before fitting?

Verify spline count, bore diameter, and face runout; measure axial clearance to ensure the pulley does not induce side loads on bearings.

How does this pulley affect differential tuning?

Lower rotating inertia reduces transient lag, which can alter how differentials behave under quick throttle inputs; retune damping and diff settings if needed.

Recommended maintenance checks for competition use?

Inspect for fretting and edge wear after each event, confirm fastener torque, and reapply appropriate grease to mating teeth to extend component life.
