FZ115S Back Plate Rear Cover YSG2046 for YS Engine  [YSG2046]

Rear back plate for FZ115S engines

This listing covers the YS Engine YSG2046 back plate designed for the FZ115S series, supplied as a dedicated replacement rear cover for RC glow engines. The component serves as a service spare to restore correct assembly and sealing when the original back plate is worn or damaged.

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

Installation is straightforward for those familiar with engine teardown: remove the outer housing, note bearing and seal positions, fit the replacement back plate making sure mounting holes align, then re-torque fasteners to the values given in the engine manual. Take care to protect bearings and gaskets while separating components.

For regular maintenance the back plate provides structural support and a sealing face; fitting a correct spare restores crankshaft alignment and seal integrity but will not modify engine performance beyond returning mechanical geometry to specification.

Keep a YSG2046 spare on hand when servicing FZ115S engines and compare it against the original part to ensure correct fitment.
