The Yokomo B10-630MA delivers a robust 20T aluminium pulley option for BD10 cars, engineered to lower belt strain and extend component life. The hard surface finish reduces friction to help maintain consistent drive behaviour during practice and competition.

It is compatible with a range of Yokomo chassis including MRTC-BD10FF, MSR-BDFWD, MSR-010, and MSR-010A, offering an easy upgrade path for longevity and reliability.
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.

What torque should I use on the pulley grub screw?

Use a moderate torque to secure the grub screw without deforming the shaft; check it after initial runs and retighten if necessary.

Will this pulley suit modified BD10 setups?

Yes, it is compatible with common BD10 modifications, but always verify belt alignment after any drivetrain changes to avoid uneven wear.

How should I clean the pulley?

Wipe away dust and debris with a soft brush and isopropyl alcohol if needed; avoid aggressive abrasives that could damage the coating.

How often will I need to replace the pulley?

With normal use the hard-coated aluminium should last a long time; replace it only if you see significant scoring or corrosion that affects belt engagement.

Does the pulley add noticeable weight to the car?

The 20T aluminium pulley adds minimal mass while improving durability, so weight impact is negligible for most BD10 setups.
