Pan Car Geardiff Bushing 4x6x3 - Arrowmax AM-931020  [AM-931020]

Precision 4x6x3 Sleeve for Geardiff Assemblies

This Arrowmax AM-931020 bushing is an RC replacement sleeve sized 4x6x3, made for use inside pan car geardiff and related differential housings on 1/12, 1/10 and F1 setups. It provides a locating surface to help control shaft runout and maintain correct gear mesh without suggesting any full-scale vehicle application.

Fitting is simple: check that the housing bore and shaft match the 4x6x3 size, clean mating faces, then press the bushing so it sits flush in the carrier. Apply a light film of lubricant on contact areas during initial run-in to reduce wear, then verify axial and radial play to ensure proper clearance.

For routine tuning and upkeep, the AM-931020 works well to tighten worn geardiff assemblies and fine-tune backlash. Inspect periodically and replace the sleeve if you see visible ovaling or excessive clearance that affects gear engagement.
