B-MAX4 III Gear Differential Case - YOKB4-503GH by Yokomo  [YOKB4-503GH]

Overview: B-MAX4 III Gear Differential Case

This is an RC-scale gear differential case made to fit the B-MAX4 III chassis, supplied as a direct replacement housing that accommodates gear-type differential assemblies. The text concentrates on fitment, service access, and how the case functions within the drivetrain without asserting extra technical claims.

Use this replacement case when you are servicing the differential on a B-MAX4 III, swapping out a damaged housing, or inspecting internal gears and bearings. The case contains the differential gears and preserves alignment and mesh that influence drive feel and balance.

Installation is straightforward for modelers familiar with differential service: extract the differential from the gearbox, move the internal gears and spacers into the new case, then reassemble while checking gear mesh and smooth rotation. The case itself does not alter differential characteristics but enables consistent reassembly and easier access for gear adjustment and lubrication.
