TB-04 drivetrain refresh with a 40T ring

The Tamiya 51547 - RC TB-04 One-Way/Gear Differential Unit Ring Gear Set (40T) is a factory-style replacement for TB-04 owners who want predictable drivetrain behaviour. The kit includes the one-way mechanism and matching 40 tooth ring to help return smooth torque flow under load.

Handling benefits and longevity

When installed correctly, the 51547 gear set reduces lash and gives a more consistent rear feel through corner transitions. The 40T ring is made to resist normal wear so it performs well over many practice sessions.

Quick service and setup tips

Installing the Tamiya 51547 is a routine job for anyone comfortable with basic RC maintenance. After fitting, confirm correct gear mesh and bearing play to avoid premature noise or wear.

Is this a direct drop-in for the TB-04?

Yes, the 51547 is made to match the TB-04 differential geometry, though builds with custom diffs or spacers should be checked for correct alignment.

What grease should I use on the gears?

Use a light gear grease or bearing-safe synthetic grease on the bearings and a thin smear on the gear faces to reduce wear without creating drag.

Does the 40T ring change gear ratios?

No, the tooth count stays the same so overall gear ratio is unchanged; you get the same ratio with more consistent engagement if installed correctly.

Should I replace other drivetrain parts at the same time?

It is good practice to inspect bearings, pinions and spur gear for wear while servicing the diff; replacing worn bearings together can prevent future issues.
