Yokomo YOKB4-503GH - BMAX4 III Gear Differential Case  [YOKB4-503GH]

Gear Differential Case for B-MAX4 III

This is an RC-scale gear differential case designed for the B-MAX4 III platform, provided as a direct replacement housing to support gear-type differential assemblies. The text focuses on compatibility, installation considerations, and the role this part plays in drivetrain setup and maintenance without claiming additional specifications.

Use this case when servicing the differential of a B-MAX4 III chassis, for replacing a worn or damaged housing, or when inspecting internal gears and bearings. It serves as the containment for the differential gears and helps maintain the alignment and mesh that affect drive feel and handling balance.

Installation is straightforward for hobbyists familiar with differential service: remove the differential assembly from the gearbox, transfer the internal gears and spacers into the new case, and reassemble while checking backlash and smooth rotation. During tuning, the case itself does not change differential behavior but enables consistent reassembly and reliable access for gear adjustments and lubrication.
