FZ115S Back Plate YSG2046 Compatible with YS Engine  [YSG2046]

YSG2046 rear plate for FZ115S series

The YS Engine YSG2046 back plate is offered as a replacement rear plate for the FZ115S range of model glow engines. It is intended as an aftermarket spare to reinstate proper sealing and rear-end assembly where the original component is compromised.

FZ115S in the product name denotes intended compatibility; verify exact engine model and serial information prior to ordering. This part is for hobby model engine use only and not for full-size machines.

For fitting, dismantle the outer casing while noting the positions of bearings and seals. Install the replacement back plate with correct alignment, then tighten fasteners to the torque settings recommended in your engine manual. Use appropriate tools to avoid damaging threads or sealing faces.

In tuning and maintenance work the back plate provides the structural reference for crank alignment. Renewing a damaged plate restores geometry and sealing but will not increase engine power beyond correct mechanical setup.

Have a YSG2046 available for FZ115S service tasks and check the new plate against the original to confirm correct fitment.
