The Yokomo BD-498L serves as the front drive belt for BD7-2015 cars fitted with a forward motor conversion. This replacement belt finalises the front-drive routing needed by the modification and is provided as a single component for maintenance or rebuilds of the front drivetrain.
How to fit: follow the forward-motor conversion routing for BD7-2015, check pulley alignment carefully, and set moderate initial tension to avoid tooth skipping while maintaining smooth rotation. Inspect the belt and pulleys for wear during fitment and perform a short test run before making final tension adjustments.
Compatibility and handling notes: correct belt alignment and tension help reduce drivetrain lash and stabilise transient behaviour under acceleration and cornering. Excessive tension can raise drivetrain drag and put additional load on bearings, so aim for a balanced setup.
