Flush Gear Mounting for BD8 with Yokomo B8-630DWA

The Yokomo B8-630DWA Aluminum M3 Countersink Washer is built to keep the main gear firmly seated on BD8 chassis variants. Sold in a two-piece set, these washers are useful for on-road setups that need precise gear alignment.

Model Compatibility

Manufactured for the MRTC-BD8 family, these washers fit BD8, BD8A, BD8-P, BD8AP, BD8SV, BD818A, and BD818 models. The countersunk shape ensures the screw head sits level with the surface for better stability.

Practical Installation Notes

Fit the washer so the countersink matches the screw head angle and depth. Proper seating reduces the chance of gear slip and contributes to steady drivetrain behaviour on smooth tarmac or carpet tracks.
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 these work with aftermarket screws?

They will if the replacement screws are M3 countersunk type and the head geometry matches the washer. Double check screw diameter and head profile before swapping.

Do they affect gear mesh settings?

The washers are thin and designed to sit flush, so they should not change mesh significantly when installed correctly. Always recheck mesh after fitting new hardware.

Are these corrosion resistant?

Aluminium resists rust but can oxidise over time. Keep contact surfaces clean and consider a light corrosion inhibitor if you run in damp conditions.
