The 3mm Yokomo YOKZC206C collar acts as a compact spacer for scale R/C chassis and drivetrains, ensuring steady gaps between bearings, pinions and other rotating components to reduce side play and improve assembly consistency.
To install, slide the collar into place where clearance must be fixed, then secure surrounding components using the vehicle's original fasteners or set screws. The collar itself does not fasten parts; final securing is accomplished with the model's existing hardware.
During setup, this collar provides a simple means to tweak mesh and preload in controlled increments, avoiding the need to re-machine parts or stack thin shims while testing different clearances.
