This Factory Pro FP-O-AP0006 main idle gear is a 28T replacement made for O-AP0004 and Tamiya T3-01 layouts in 1/10 scale RC cars. It functions as the centre idle gear that supports the spur and keeps the drivetrain mesh correct when the motor is not driving the spur directly.
The part is precision machined to maintain a consistent tooth profile and suits routine maintenance or swapouts. During installation inspect adjacent bearings and the spur for wear, confirm axial alignment, and set mesh and shims so the gear spins freely without binding.
From a setup perspective this idle gear affects drivetrain neutrality and coast noise, so check backlash and bearing fit as part of tuning. Use it as a direct swap for worn or damaged idle gears matched to O-AP0004 mounting and the T3-01 gear train layout.
