Fine adjustment cams for BD7/BD5/DRB drivetrains

This Yokomo B7-BTC set contains four resin belt tension cams made for 1/10-scale touring chassis. The parts are moulded in lightweight resin to keep added mass minimal while allowing quick belt-tension adjustments without replacing larger components.

The cams sit on the belt path to change tension take-up and contact point, offering an accessible way to refine drive feel and belt stability during setup. Installation is straightforward for anyone familiar with belt-drive touring cars: remove the relevant belt cover and swap the existing cams in place. Treat these as RC-scale parts and follow chassis-specific service procedures rather than general automotive processes.

Tuning tips: make small, incremental changes and recheck belt alignment and runout after each adjustment. Because the cams are resin, avoid over-tightening nearby fasteners to prevent distortion. These parts suit hobby mechanics wanting a low-mass option to fine-tune belt behaviour on the listed chassis.

What exactly is included in the kit

The package includes four resin belt tension cams, enough to service both sides of the drivetrain on compatible touring chassis.

Are these resin cams a direct substitute for metal versions

They fit in place of existing cams on the listed models, but resin is lighter and generally less abrasion resistant than metal, so expect different wear characteristics.

How should I approach tension adjustments with these cams

Adjust tension in small increments, inspect belt alignment after each step, and avoid over-tightening screws adjacent to the resin cams to prevent deformation.
