Spur hub upgrade for Yokomo drift chassis

The RD-630P is a lightweight spur gear hub designed to serve as a direct replacement on Yokomo RD, SD, and MD drift platforms. With a larger-diameter profile the spur sits closer to the gear case, which reduces vibration and helps preserve consistent mesh during lateral loads encountered in drifting.

The hub's placement lessens side load on the top shaft during sudden throttle changes, which contributes to a more predictable acceleration characteristic. The geometry is intended to boost spur retention and allow smoother rotation with fewer jolts.

When replacing series-standard spur hubs (for example Y4-630A, Y2-630PA, Y2-630RA) be aware the set-screw location is different. The RD-631 aluminium top shaft may be required to match the screw fixing position for secure installation.

Fit the RD-630P where improved spur stability and reduced vibration are desired; confirm top-shaft compatibility and use the RD-631 aluminium top shaft if the set-screw alignment does not match.
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 I need to change any other parts to fit the RD-630P?

The hub fits the listed RD/SD/MD models, but because the set-screw sits in a different location you may need the RD-631 aluminium top shaft to secure the hub correctly.

Are there specific models in the compatibility list that need special attention?

Inspect older or modified variants for wear or non-standard top shafts; while the RD-630P lists many compatible models, physical inspection of the set-screw alignment is recommended before final assembly.

How should I verify correct gear mesh after swapping hubs?

After installation, rotate the drivetrain by hand and check mesh under load; adjust pinion position or shimming as required to maintain quiet, consistent contact between spur and pinion.

What if the hub wobbles after fitting?

If you detect runout, ensure the hub is seated fully and the set-screw is tightened to the correct torque. Confirm the top shaft is not worn and replace with RD-631 if alignment problems persist.
