This steel 16-tooth motor pinion is an aftermarket replacement designed for TRAXXAS 1/8 X-Maxx applications and is supplied as 1 pcs. It acts as the motor-side pinion that transfers torque into the drivetrain, intended for hobby electric setups needing a direct-fit replacement pinion.
Fit and function: the pinion matches the X-Maxx motor interface profile referenced in the product title, and replaces worn or damaged motor gears while keeping the vehicle gear ratio the same at 16 teeth. Always check gear mesh and set-screw engagement when installing to avoid excessive backlash or binding.
Installation notes: fit using standard pinion replacement procedure, confirm correct axial position and secure mounting on the motor shaft, then verify smooth engagement with the spur gear under free rotation before testing under load. Perform conservative initial runs to confirm correct operation.
