Connecting rod for FZ115S engine

This YS Engine connecting rod YSG2045 is the factory-design spare intended for use with the FZ115S RC-scale engine family. It serves the mechanical role of linking piston motion to the crankshaft inside the engine assembly and is intended as a direct replacement part when wear or damage is detected during routine service or rebuilds.

Installation requires standard engine disassembly and careful reassembly: inspect mating surfaces and bearings for wear, ensure clean lubrication during assembly, and verify correct fitment before testing. Because this is a component inside the powerhead, correct alignment and torque on fasteners are important to avoid premature wear.

For tuning and maintenance tasks this connecting rod should be treated as a service item — replace when run-time or inspection indicates fatigue, and always double-check clearances after a rebuild to maintain consistent engine behavior.
