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

Washer and ball service kit for Mini Inferno running gear

This rebuild set provides the replacement washers and bearing balls intended for Kyosho Mini Inferno series models that reference MIF-047, supplied as part MIF-047RB. The kit is aimed at renewing small drivetrain components that affect rotational smoothness and reduce play on Mini Inferno and Mini Inferno ST cars.

Compatibility is limited to Kyosho Mini Inferno and Mini Inferno ST assemblies using the MIF-047 service point; do not fit the parts outside that scope. Installation follows standard small-scale drivetrain service steps: access the affected assembly, remove worn washers and balls, clean mating surfaces, fit the new components, apply an appropriate light lubricant to moving interfaces, and reassemble to the original torque and alignment settings. This is a precision RC-scale maintenance procedure.

From a setup perspective this kit is a basic maintenance item: replacing worn washers and balls reduces slop in rotating parts, helps the drivetrain run more consistently, and supports repeatable testing or hobbyist servicing. The set restores original component function without altering final gearing, suspension geometry, or electronics configuration.
