YS Engine YSG2046 back plate FZ115S replacement rear cover for RC glow engine spares  [YSG2046]

Back plate for FZ115S engine

This listing covers the YS Engine back plate intended for the FZ115S series, supplied as a dedicated replacement rear cover for RC-scale glow engines. The component serves as a service spare to restore correct assembly and sealing where the original back plate is worn or damaged.

Compatibility is indicated by the FZ115S designation in the product name; confirm your engine model and serial details before ordering. The part is intended for hobby-grade model engines only and not for any real vehicle application.

Installation is straightforward for those familiar with engine disassembly: remove the outer housing and observe bearing and seal positions, replace the back plate ensuring alignment of mounting holes and re-torque fasteners to the values recommended by the engine manual. Use care to preserve bearings and gaskets when separating components.

In routine tuning and maintenance the back plate acts as a structural and sealing element; swapping a worn plate can support proper crankshaft alignment and seal integrity but will not alter engine performance characteristics beyond restoring factory geometry.

Keep this spare on hand when servicing FZ115S engines and verify fitment against the original part to ensure correct assembly.
