TAMIYA TT02/TT02B Precision Small Bevel Gears TT2100/G4 by GPM  [TT2100/G4]

Steel small bevel gear replacement for TT02 differentials

This four-piece steel small bevel gear set is specified as a direct replacement for TAMIYA TT02 and TT02B differential and internal gear train applications. The focus is on improved wear resistance and repeatable gear mesh during typical RC use.

In service, the small bevels transmit torque within the differential and gearbox assemblies between mating bevel gears. Selecting steel for these components enhances wear life compared with softer materials and supports more frequent operation or higher load conditions.

Assembly notes: remove the differential carrier, inspect mating gears and bearings for wear, orient the small bevels correctly during installation, and establish correct mesh before final assembly. Use an appropriate diff fluid or light grease for your TT02 differential and confirm smooth drivetrain rotation.

The TT2100/G4 steel small bevels provide a robust replacement to extend service life of TT02 drivetrain components; verify mesh and clearances on the actual diff build before extended use.
