TAMIYA XV-02 PRO 1/10 Spur Gear 70T M0.6 by GPM XV23570TS  [XV23570TS]

Spur gear and holder for XV-02

This listing covers a replacement spur gear and matching spur gear holder designed for the TAMIYA XV-02 PRO 1/10 chassis. The pair is specified as a 70T spur with M0.6 module teeth, manufactured in medium carbon steel to balance wear resistance and running smoothness in RC drivetrains. The assembly is intended purely for model-scale RC use and not for any full-size application.

The spur gear provides the large reduction stage between the pinion and the gearbox input, and the included holder secures the gear to maintain concentric rotation under load. Proper seating of the spur and stable bearing support are essential to prevent uneven wear and to preserve gear mesh quality during high-speed runs.

Installation notes: remove the existing spur assembly, fit the 70T spur onto its mounting hub, position the holder to align the gear with the gearbox input, and verify tooth engagement across the mesh before final tightening. After installation, rotate the drivetrain by hand to confirm smooth operation and check for lateral play that can indicate bearing or shaft issues.

Tuning role: swapping to this medium carbon steel 70T spur can change overall drivefeel and durability compared with softer materials; use it as part of a refinement process when adjusting pinion size, motor timing, or ESC settings for desired acceleration and top-speed balance.

For layout stability and predictable wear, check spur-to-pinion backlash after a short break-in period and inspect the holder fastenings periodically; this set is suited for hobby-grade 1/10 XV-02 PRO setups where a durable steel spur is required.
