Front tensioner details for BD9

This RC-scale front belt tensioner is manufactured for use with the BD9 platform and replaces the front belt tensioner assembly to ensure correct belt routing and alignment on BD9-derived chassis.

Sold as a replacement spare for hobby use; always confirm your chassis model code against the compatibility list before fitting. Common uses include replacing tensioners that have worn with time or using a spare during setup and adjustments.

As part of setup and tuning the front tensioner impacts belt tracking and the belt's response under load, so after installation verify belt alignment and fasteners to maintain consistent belt performance.

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.

How does this tensioner affect handling when tuning?

The tensioner changes belt tracking and load response at the front drivetrain, which can influence steering feel; ensure consistent installation to evaluate tuning changes accurately.

Should belt tension be adjusted after fitting?

Yes. After installing the tensioner recheck belt tension and alignment, then make incremental adjustments while testing to find the desired behaviour.

Can I reuse the original mounting hardware?

If the original fasteners are undamaged they can typically be reused, but always ensure they are torqued correctly and that there is no play in the mounting points.
