This steel 16T motor pinion is an aftermarket replacement for TRAXXAS 1/8 X-Maxx and is supplied as one piece. It functions as the motor-side pinion that delivers torque from the motor into the drivetrain for hobby electric vehicles requiring a direct-fit swap.
Compatibility and use: the part aligns with the X-Maxx motor interface profile described in the product title, intended to replace worn motor gears while keeping the original gear ratio at 16 teeth. Always check pinion-to-spur mesh and set-screw seating during fitting to avoid gear damage.
Installation guidance: fit the pinion using standard procedures, confirm correct axial placement, secure the set-screw, and rotate the drivetrain by hand to ensure smooth engagement before live testing. Start with light runs to confirm correct installation.
