Yokomo YOKB4-503GH Replacement Gear Case for B-MAX4 III  [YOKB4-503GH]

B-MAX4 III Gear Housing Details

This gear differential case is produced for the B-MAX4 III platform as a replacement internal housing that secures gear-type differential components. The description focuses on compatibility, serviceability, and the role of the case in drivetrain upkeep without stating additional specifications.

Ideal when performing differential maintenance on a B-MAX4 III chassis, replacing a worn housing, or checking gears and bearings. The case holds the differential gears and helps maintain correct alignment and mesh that affect traction and balance.

Swapover is accessible to hobbyists comfortable with differential service: remove the differential assembly, transfer gears and spacers into the new housing, then reassemble while monitoring backlash and free rotation. The housing permits consistent rebuilds and simpler gear adjustments but does not itself change differential tuning.
