Kyosho Mini Inferno Drivetrain Washer and Ball Kit MIF-047RB by 3Racing  [MIF-047RB]

Mini Inferno drivetrain washer and ball kit

This rebuild package contains the replacement washers and balls for Kyosho Mini Inferno-series cars that reference MIF-047, sold as part MIF-047RB. It is intended to swap out small, worn drivetrain parts that cause rough rotation or excess play on Mini Inferno and Mini Inferno ST models.

Only use these items where the vehicle specification lists the MIF-047 rebuild point. Service is straightforward: dismantle the affected area, remove the old washers and balls, clean the bearing and mating surfaces, install the new parts, apply light lubricant to moving contacts, then reassemble to the original alignment and torque values. This is standard RC-scale maintenance work.

In practical tuning terms the kit is a maintenance refresh: it reduces mechanical slop in rotating components and helps the drivetrain deliver more predictable performance during hobby testing or club track sessions. It restores factory function rather than changing drive ratios or suspension settings.
