Installation-focused belt tension cam for BD7/BD5/DRB

This aluminium belt tension cam secures the bearings at both ends of the differential, for one-way and spool units, and lets you adjust belt tension by turning both sides at once. It is produced as an RC replacement part to keep bearing alignment and let you fine-tune belt preload on compatible touring car chassis.

Fit this cam when you need symmetric tension changes without altering mount positions: rotate the cam halves together to increase or reduce belt tension while keeping bearing locations fixed. The design prioritizes straightforward servicing and consistent preload rather than changing suspension geometry.

Packing includes

  • Belt tension cam - 1 pcs
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 do I install the cam on BD7/BD5/DRB chassis?

Match the cam to your existing mount points, seat the bearings fully, then tighten fasteners while confirming both cam halves rotate together. Verify the mount locations on your BD7, BD5 or DRB before fitting.

Is the cam compatible with one-way and spool differentials?

Yes. The aluminium cam is designed to hold bearings at both ends of one-way and spool assemblies so you can retain proper bearing location while adjusting belt preload.

Any tips for adjusting tension during install?

Rotate the cam halves evenly as you tighten to achieve the desired preload, then run the drivetrain slowly to confirm there is no binding before full use. Check alignment after a short test run.
