Arrowmax AM-931015 Bushing 4.6X6.5X4 for Pan Car Geardiff  [AM-931015]

Pan Car Geardiff Bushing 4.6×6.5×4

This Arrowmax AM-931015 bushing is an RC-scale component sized 4.6×6.5×4 intended for use in pan car geardiff assemblies. Its primary role is to locate shafts and control lateral play within the diff stack, supporting consistent gear engagement during running and setup.

Installers should verify fitment by measuring bore and shaft diameters before assembly, press the bushing into the housing with moderate force, and confirm smooth rotation of the mating shaft. Use appropriate light lubrication on contact surfaces to reduce initial break-in wear and avoid excess friction that could affect diff behavior.

In tuning, replacing worn or oversized bushings is a straightforward way to restore consistent backlash and improve repeatability between runs. Swapping bushings can change perceived gear mesh and freeplay, so check gear engagement and diff preload after any change.
