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

Spur gear set for XV-02 PRO builds

This item is a 70-tooth M0.6 spur gear and matching holder designed for the TAMIYA XV-02 PRO 1/10 chassis. Manufactured from medium carbon steel, the set is tuned for a balance of wear resistance and smooth gear mesh under normal RC driving conditions and is for model use only.

The spur provides the large reduction stage between pinion and gearbox input while the holder keeps the gear coaxial under load. Correct seating and robust bearing support reduce uneven wear and help retain consistent mesh quality during high-speed or prolonged use.

Fitting instructions: remove the existing spur assembly, install the 70T gear on its hub, position the holder to align the gear with the gearbox input, and verify tooth engagement across the mesh before final tightening. Hand-rotate the drivetrain after fitting to confirm smooth operation and to spot any lateral play from bearings or shafts.

Tuning advice: switching to this medium carbon steel 70T spur can change the drivefeel and increase durability versus softer options; consider pinion changes and motor/ESC setup when tuning for desired acceleration and top speed.

Monitor spur-to-pinion backlash after a short break-in and inspect the holder mounting regularly; this assembly is suited to 1/10 XV-02 PRO hobby rigs needing a more robust steel spur option.
