Tamiya 3485036 - Rear Shaft Replacement for 58198/194/174/156  [3485036]

Installation notes for rear shaft on F1 and GT chassis

This is an RC-scale rear shaft listed as Tamiya 3485036 and intended to serve as a direct replacement for items identified by part numbers 58198, 194, 174, and 156. The part is a rear drive shaft intended for use in F1 and GT style scale chassis where those part codes are specified.

Functionally the shaft replaces a worn or damaged rear axle component inside the rear differential or gearbox assembly on compatible RC models. When installing the replacement, verify smooth rotation and correct seating in the differential to avoid binding; alignment and clearance at the transmission interface will influence driveline feel and prevent premature wear.

For straightforward service swaps, remove the old shaft, clean mating gears and bearing surfaces, and confirm the chassis turns freely before final assembly. This component is intended to restore the original driveline geometry rather than to alter vehicle-scale performance.
