YS Engine YSG1047 Back Plate Screw for FZ70S Rear Plate  [YSG1047]

FZ70S Rear Plate Screw Details

This is an RC-scale back plate screw supplied for the YS Engine YSG1047 line, intended specifically for the FZ70S rear plate assembly as indicated in the product name. The part acts as a direct replacement fastener to restore or maintain the mechanical fixing of the engine's rear cover.

Installation is straightforward: align the rear plate, start the screw by hand to ensure correct thread engagement, and tighten until the plate sits flush and stable. Avoid over-tightening to prevent thread damage; a correctly seated screw helps maintain sealing and reduces the chance of loosening under vibration during operation.

In maintenance and tuning situations this screw plays a small but essential role, keeping the rear plate secure so internal components remain contained and accessible. Keep one as a service spare for routine upkeep or when the original fastener is worn or missing.
