B-Max4 Front Gear Box Repair Part - YOKBM302F for Yokomo  [YOKBM302F]

Replacement Front Gearbox for B-Max4 Chassis

This front gear box is supplied as a replacement assembly for use with the B-Max4 platform. It is intended to serve as a direct spare for front drivetrain maintenance without requiring chassis modification.

The item corresponds to model YOKBM302F and is intended to re-establish factory drivetrain geometry and mounting positions on B-Max4 cars. It is an accessory for RC use only and not suitable for real vehicles.

Fitment notes: remove the front bulkhead or access panel following your chassis manual, inspect or transfer internal gears and bearings when appropriate, set correct gear mesh and axial alignment before final torque, and apply a small amount of proper grease to mating gears to limit wear. Confirm drive shafts and servo linkages rotate freely after installation and run a slow test to verify operation.

Compatibility advice: this listing is intended for B-Max4 platforms. If you are considering the part for another model, compare mounting points and gear train layout to confirm compatibility before ordering.
