Ring gear maintenance and compatibility notes

The Tamiya 51704 Ring Gear Set is designed to service the XV-02 and TT-02 families. The 39T unit is presented as the practical, widely compatible option, while the 40T may not suit every vehicle setup. Always confirm clearance before fitting the larger ring.

Where this set fits

Intended for use with XV-02 PRO, TT-02, TT-02D and TT-02 Type-S gear assemblies, this ring gear keeps driveline operation smooth when installed correctly. Replacing worn gears helps prevent sudden failures and maintains predictable handling. Check the Tamiya R/C Parts Matching List for precise fit information.

Is the 39T better for circuit running?

For most circuit and club track setups the 39T gives reliable mesh and consistent gearing. The 40T can change final drive and may need additional clearance checks.

Will XV-02 PRO accept this ring gear without mods?

Yes, the 39T fits standard XV-02 PRO gearboxes as intended. If you plan to use the 40T, verify pinion position and bearing spacing to avoid interference.

Do I need to grease the gear teeth?

A light coating of appropriate gear grease helps reduce wear and dampens noise. Avoid over greasing which can attract grit and accelerate wear on exposed tracks.
