Tamiya T3-01 28T Main Idle Gear Service Part - O-AP0006 by Factory Pro  [FP-O-AP0006]

Service idle gear for Tamiya T3-01 systems

The Factory Pro FP-O-AP0006 main idle gear is a 28T spare designed for O-AP0004 and Tamiya T3-01 drivetrain arrangements in 1/10 scale RC cars. It functions as the intermediate idle gear supporting the spur when the motor is not directly engaged with the spur gear.

Produced with a precision-machined tooth profile, this component is intended for routine maintenance and replacement. When fitting the gear inspect surrounding bearings and the spur for wear, confirm axial alignment, and set mesh and shims so the gear runs free without tight spots.

This idle gear can influence drivetrain balance and coasting sound, so include backlash and bearing checks as part of setup changes. Fit it as a direct swap for worn or damaged idle gears matching O-AP0004 mounting and the T3-01 gear train layout.
