This aluminium differential shaft is produced as a direct-fit service component for TAMIYA TA05 series models including TA05, TA-05IFS and TA05-R. The part reference is TA05-19/V2/LB and it is intended for installation within the differential carrier of these chassis.
Recommended installation procedure: disassemble the differential case, inspect internal gears and bearings for wear, replace the service shaft with the aluminium unit, then reassemble while setting correct bearing preload and gear mesh. The component is intended for scale model maintenance and tuning only.
From a tuning viewpoint, the aluminium shaft offers consistent rotational characteristics and improved resistance to shaft wear compared with many stock plastic shafts. Confirm dimensional match with the original shaft and ensure 走珠軸承 and gear engagement surfaces are free of contamination before final assembly.
