Yokomo YOKBM302F - BMax4 Front Gear Box  [YOKBM302F]

B-Max4 Front Gear Box

This is a replacement front gear box assembly intended for RC-scale use with the B-Max4 platform. The component is provided as a direct spare for servicing the front drivetrain and replacing a worn or damaged gearbox unit without modifying the chassis.

Designed as a like-for-like replacement, the part corresponds to model YOKBM302F and is intended to restore factory drivetrain geometry and mounting points on B-Max4 cars. It is an RC accessory only and not for any real vehicle application.

Installation notes: remove the front bulkhead or access plate as per your chassis manual, transfer or inspect internal gears and bearings when applicable, check gear mesh and axial alignment before final torqueing, and use a small amount of appropriate grease on mating gears to prevent premature wear. Verify servo linkages and drive shafts for free rotation after installation and perform a low-speed test run.

Tuning role: swapping the front gear box is a routine maintenance step that supports consistent steering response and predictable power transfer at the front end, and it facilitates gear mesh adjustments and bearing replacement during setup or repair cycles.
