Replacement front tensioner for BD9

This RC front belt tensioner kit is built for BD9 platform use and replaces the standard front belt tensioner assembly to correct belt routing and alignment on compatible BD9-based chassis.

Provided as a spare or replacement part for hobby use; always confirm your chassis code against the compatibility entries before fitting. Typical scenarios include swapping out a worn tensioner after extended running or keeping a spare for event days.

The front tensioner can influence belt behaviour under load during setup and tuning, so after installation recheck belt tracking and ensure mountings are secure to maintain consistent operation.

Compatibility

  • MRTC-BD919
  • MRTC-BD919S
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 every BD9 variant?

It is intended for BD9-derived chassis listed under Compatibility. Check the exact model code on your chassis to confirm compatibility before purchase.

Is this part suitable as a spare during events?

Yes. Its purpose is to serve as a direct replacement for worn components or as a spare to swap in quickly during setup or between runs.

How do I monitor wear on the tensioner?

Inspect pulley faces and mounting points for play or visible wear; if belt tracking becomes inconsistent, consider replacement.
