TAMIYA TT02/TT02B Small Steel Bevel Gear Upgrade TT2100/G4 by GPM  [TT2100/G4]

Steel small bevel gear replacements for TT02 series

This four-piece steel small bevel gear set is supplied as a replacement hop-up for TAMIYA TT02 and TT02B chassis. The gears are intended for differential and internal gear train applications where improved wear life and stable mesh are priorities.

These bevel gears operate inside the differential and associated gear trains to transmit torque between mating bevels. The steel option increases resistance to wear compared with common softer materials, which benefits models run frequently or under increased load.

Installation guidance: remove the diff carrier, inspect the mating bevels and bearings for signs of wear, fit the steel small bevels with correct orientation, and set gear mesh before completing reassembly. Choose the diff fluid or grease appropriate for your TT02 differential and check that the drivetrain turns freely.

The TT2100/G4 steel small bevels offer a reliable replacement path for maintaining TT02 drivetrains where steel is preferred for longevity; always verify mesh and clearances on your specific diff assembly before extended operation.
