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

Main idle gear for Tamiya T3-01

This Factory Pro FP-O-AP0006 Main Idle Gear is a 28T replacement designed for O-AP0004 and Tamiya T3-01 applications in 1/10 scale RC cars. It serves as the central idle gear that supports the spur and keeps the drivetrain mesh stable when the motor is not driving the spur directly.

The component is described as a precision-machined item suitable for routine maintenance and part replacement. When replacing an idle gear, inspect the surrounding bearings and spur gear for wear, confirm axial alignment, and set mesh and shims so that the gear spins freely without binding.

In tuning terms, this idle gear affects drivetrain neutrality and noise under coast, so check backlash and bearing fit as part of setup adjustments. Use it as a direct swap for worn or damaged idle gears matched to O-AP0004 mounting and the T3-01 gear train layout.
