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

BD-630 adapter: product overview

This component converts the BD5 centre one-way main gear adapter into a direct main gear adapter by removing the one-way element, creating a fixed connection in the drivetrain centre assembly. It is a model-scale replacement part intended for on-road vehicles where a direct main gear is required for particular setup goals.

The supplied kit contains the axle pin required for installation. Installing this adapter removes the freewheeling feature of the one-way unit, altering how power is transferred while coasting and under reverse torque. It is chosen when drivetrain configuration is used to tune traction and handling rather than changes to suspension or differentials.

Pre-fit checks: inspect centre assembly clearances, ensure the main gear lines up with the spur and pinion gears, and fasten retaining hardware to the torque recommended by your chassis documentation. This item alters drivetrain function at the scale model level and is intended for hobby RC use only.

Compatibility

Compatible with the BD5 drive system centre assembly as a direct main gear adapter replacement and intended for use with Yokomo BD5 on-road drivetrains.
