Upper centre transmission case explained

The Yokomo SD-302DU upper centre transmission case is an aluminium replacement housing designed for use with D-MAX standard components. It holds the top section of the centre gearbox, ensuring stable gear mesh and offering a dependable mounting face for bearings and shafts.

To fit the unit, remove the original upper case, move across the bearings and gears intact, then install the SD-302DU and retighten fasteners while checking mesh and shaft alignment. Using the same bearing sizes and fastening paths prevents unintended changes to drivetrain geometry.

As an upgrade item, a rigid aluminium upper case aids drivetrain stiffness and improves serviceability. The SD-302DU helps preserve correct gear engagement under load and makes maintenance and setup adjustments more straightforward.
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.

Will this fit modified D-MAX kits as well as stock ones?

The SD-302DU is intended for D-MAX standard parts; minor modifications may be required for heavily altered kits. Verify bearing locations and fastener clearances if your build departs from standard geometry.

Can I reuse the original bearings when installing the SD-302DU?

Yes, transfer the existing bearings where they match the same sizes and seating positions. Reuse is recommended to maintain intended shaft spacing and to avoid altering mesh unless new bearings are deliberately chosen.

Does this part require any electrical grounding or insulation steps?

No special grounding is required for the SD-302DU in typical radio-controlled drivetrain applications; focus on clean mating surfaces and correct fastener torque to ensure reliable mechanical performance.
