BD5 Direct Main Gear Adapter for Yokomo BD-630  [BD-630]

BD-630 direct-drive adapter summary

This accessory converts the BD5 center one-way main gear adapter into a direct main gear adapter by removing the one-way mechanism, producing a direct-drive connection in the center assembly. It is a scale RC replacement intended for on-road cars where a fixed main gear is preferred for setup or tuning choices.

The adapter ships with the axle pin required for fitment. Fitting this adapter changes center drivetrain behaviour by removing the freewheeling action of the one-way unit, which alters power transfer under coasting and reverse load conditions. Use this option when you want to influence traction and handling through driveline configuration rather than through suspension or differential adjustments.

Installation notes: inspect center assembly clearances, confirm alignment of the main gear with the spur and pinion gears, and secure retaining hardware to the torque settings recommended for your chassis. This item modifies drivetrain function at the scale-model level and is intended for hobby RC use only.

Compatibility

Designed to fit the BD5 drive system center assembly as a direct main gear adapter replacement, suitable for Yokomo BD5 on-road drivetrain configurations.
