Replacement Gear Differential Case Overview

This gear differential case is designed specifically for the B-MAX4 III chassis and is supplied as a direct replacement housing for gear-type differential assemblies. The description emphasises fit and service access while avoiding additional specification claims.

Install this case when carrying out differential maintenance on a B-MAX4 III, replacing worn housings, or inspecting internal gearsets and bearings. It contains the differential internals and helps keep gear alignment and mesh that affect handling consistency.

Fitting is straightforward for hobbyists experienced with differential work: remove the differential, move gears and spacers into the new housing, then reassemble while checking backlash and rotation. The housing ensures repeatable rebuilds and convenient access for adjustment and lubrication but does not alter the differential's inherent behavior.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Is this an exact replacement for the factory case?

It is offered to match the B-MAX4 III's differential layout; confirm your chassis revision and mounting details to ensure it aligns with the original housing dimensions.

How can I check the case for wear after use?

Inspect mating surfaces, screw bosses, and internal bearing seats for deformation or scoring, and check gear teeth for abnormal wear patterns that could indicate misalignment.

Do different materials impact longevity?

Material choice can affect durability and resistance to impact; however, regular inspection and correct assembly are the primary factors in achieving long service life.
