The Yokomo BM-670WP is an aluminium replacement slipper plate intended for B-MAX4W-series off-road chassis. It supplies a reliable bearing surface for the slipper clutch to ensure repeatable engagement and controlled torque flow to the drivetrain.
Fitting the plate is a routine task for those familiar with drivetrain assemblies: remove the gear cover and slipper items, place the new plate in the same orientation, then reassemble and check engagement and clearance. Never force parts and verify smooth operation before use.
Setup advice focuses on preload tuning: tighter settings increase initial traction and can sharpen acceleration but may promote wheel hop; looser settings reduce drivetrain shock and soften launches. Make small, measured changes and evaluate on your usual surface.
Keep the plate performing by visually inspecting for wear, removing trapped debris, and ensuring the contact face remains flat. Replace when wear is noticeable to retain predictable slipper performance.
