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

Summary of the screw pack

The 3Racing 416-10B screw pack is supplied as a replacement set for the TAMIYA TRF 416 differential assembly, intended to restore secure fastening during maintenance and rebuilds at model scale.

Targeted at hobby mechanics, the pack replaces damaged or worn fastening hardware that secures diff components, aiding correct alignment on reassembly and supporting predictable preload when tuning the unit.

Fitting notes: strip the differential following TRF 416 service instructions, move internals as required, and refit the replacement screws with even torque to avoid distortion. Confirm free-running of the rotating elements after reassembly and take care not to strip small threads by over-tightening.

Workshop advice: renewing fasteners when changing oils or shims reduces assembly variation and helps maintain consistent differential action on the TRF 416 chassis.
