Precision XV-02 PRO 70T M0.6 Spur Gear XV23570TS by GPM  [XV23570TS]

Technical overview for XV-02 spur assembly

This assembly includes a CNC-friendly 70T spur with M0.6 tooth profile and a matching holder designed for fitment on the TAMIYA XV-02 PRO 1/10 chassis. Manufactured in medium carbon steel to provide a measured increase in wear resistance while maintaining acceptable run-in characteristics for hobby drivetrains.

The spur supplies the principal reduction stage between the pinion and gearbox input shaft, and the holder secures axial alignment to maintain concentric rotation under torque. Correct hub seating and robust bearing support are crucial to prevent eccentric wear and to preserve gear mesh integrity at higher rotational speeds.

Installation procedure: remove the original spur assembly, mount the 70T spur on its hub, align the holder to register the gear with the gearbox input, then verify tooth engagement evenly across the mesh prior to final torque. Manually rotate the drivetrain post-fitment to verify smooth operation and to detect any lateral play indicative of bearing or shaft wear.

Tuning and durability notes: opting for medium carbon steel changes the wear profile and tactile feedback versus softer materials; use this component as part of a staged tuning approach, adjusting pinion size, motor timing, and ESC parameters to achieve the desired acceleration and top-end balance.

For consistent operational life, set measured backlash and inspect holder fastenings after initial running; this component is intended for hobby 1/10 XV-02 PRO builds requiring engineered steel gearing.
