TAMIYA TT02/TT02B Steel Small Bevel Gears, 4 pcs by GPM TT2100/G4  [TT2100/G4]

Steel small bevel gears for TT02

This is a set of steel small bevel gears intended as replacement hop-up parts for TAMIYA TT02 and TT02B RC chassis. The kit contains 4 pcs designed for the differential and internal gear trains in TT02-series models; the focus is durability and consistent gear mesh under normal RC running conditions.

In practice these small bevels serve inside the differential and gearbox assemblies to transfer torque between mating bevel gears. Using steel for the small bevels improves wear resistance compared with common soft alloys, which helps when the model is run frequently or under higher loads typical of tuned motors and heavier setups.

Installation notes: remove the diff carrier, inspect mating bevels and bearings for wear, fit the steel small bevels with correct orientation, and check gear mesh before final reassembly. Use the diff fluid or grease appropriate for your TT02 differential design and verify smooth rotation through the drivetrain; do not force parts or alter teeth profiles.

The GPM TT2100/G4 steel small bevels are a straightforward replacement part for maintaining or slightly upgrading the TT02 drivetrain where steel gears are preferred for longevity; confirm fit and mesh on your specific diff build before extended use.
