TAMIYA TRF 416 Differential Screw Set by 3Racing 416-10B  [416-10B]

Differential screw set overview

The 3Racing 416-10B is a dedicated replacement screw set supplied for the TAMIYA TRF 416 differential assembly. It is intended as a maintenance and rebuild part to restore secure fastening within the differential housing and to support routine service of the TRF 416 chassis at model scale.

This set is positioned for hobbyists who service their differentials: it replaces worn or damaged screws that hold diff components together, helps maintain correct alignment during reassembly, and supports consistent preload when tuning the unit. The description focuses on compatibility and the part's role rather than performance claims.

Installation notes: disassemble the differential as per the TRF 416 service steps, transfer internals as needed, and refit the replacement screws evenly to avoid misalignment. Check that the rotating elements move freely after reassembly. Use appropriate tightening practice for small-scale hardware to avoid stripping threads.

Practical tuning context: when adjusting differential action on a TRF 416, having fresh, undamaged fasteners ensures repeatable assembly and reliable torque distribution across the diff case, which helps when changing oils or shims during setup.
