Arrowmax AM-931020 Bushing 4x6x3 for 1/12 1/10 F1 Pancar Geardiff  [AM-931020]

4x6x3 Bushing for Geardiff

This Arrowmax bushing is an RC-scale replacement sleeve sized 4x6x3 intended for use inside pan car geardiff and related differential assemblies in 1/12, 1/10 and F1 setups. It serves as an internal locating surface to control shaft runout and gear mesh clearance without implying any full-scale vehicle use.

Installation is straightforward: verify the bore and shaft sizes match the 4x6x3 dimension, clean mating surfaces, and fit the bushing so it seats flush in the housing. Light lubrication on the contact surfaces can reduce initial break-in wear, and a careful check of axial and radial play after fitment helps confirm correct clearance.

For tuning and maintenance, this bushing is a small but useful item to restore tightness in worn geardiff assemblies or to fine-tune mesh and backlash. Regular inspection for wear is recommended, replacing the bushing if you observe visible ovaling or excessive clearance that affects gear engagement.
