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

Technical rebuild kit for Mini Inferno drive components

This technical rebuild set provides the exact washers and balls specified for Kyosho Mini Inferno platforms that reference MIF-047, packaged under part MIF-047RB. The components are intended to replace worn contact items that influence rotational precision and driveline play on Mini Inferno and Mini Inferno ST chassis.

Use only where the service documentation cites the MIF-047 reference. Recommended procedure: disassemble the affected subassembly, remove the worn washers and balls, degrease and inspect mating surfaces for wear, install the new parts ensuring correct seating, apply a measured amount of light lubricant to the metal-to-metal interfaces, and torque fasteners to the original specifications. This is a standard RC maintenance operation that restores designed clearances and movement.

From a setup and tuning viewpoint the kit serves as a preventative refresh: replacing fatigued washers and balls lowers mechanical backlash, improves rotational repeatability, and helps maintain consistent test results. It reinstates factory mechanical behaviour without altering gear ratios, ride geometry, or electrical configurations.
