Maintain Consistent Belt Tension with a Precision Cam

The Yokomo B9-BTCBA Precision Resin Belt Tension Cam is a machined resin part created to keep belt tension steady and improve drivetrain consistency. Its precise profile reduces belt slack and supports predictable handling at speed.

Precision Machining Advantages

Machining delivers uniform surfaces and tight tolerances that reduce variance between parts, which helps diminish belt play and enhances throttle and steering fidelity on the track.

Designed for Multiple Yokomo Frames

This cam is compatible with numerous Yokomo models from the MRTC and MSR series listed below. It is engineered to align with common belt routing and mounting details to ease installation.

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 cam improve lap-to-lap consistency?

Yes, by reducing changes in belt tension the cam helps keep handling more consistent between runs, which is useful when tuning for repeatable lap times.

Is additional tuning required after fitting?

After installation check belt tension and make minor trim adjustments to your setup if necessary, but major tuning changes are rarely needed just for this swap.

What maintenance should I perform?

Regularly inspect the cam for surface wear or cracks and confirm belt alignment and tension after any hard impacts or extended running sessions.

Can I use this with belt-driven conversions?

It is intended for the listed Yokomo belt systems; if your conversion keeps the original belt geometry and mounts, the cam should be compatible, but always double-check clearances.
