YS Engine YSG2045 Precision Connecting Rod for FZ115S Engines  [YSG2045]

YSG2045 Durability Notes for FZ115S

This YS Engine connecting rod YSG2045 is supplied as a spare matching the factory design for the FZ115S RC engine family. It transmits piston movement to the crankshaft within the powerhead and serves as a direct replacement when routine inspection reveals wear or damage.

Replacement involves standard engine strip-down and careful reassembly: examine bearing journals and mating faces for wear, use clean lubrication during assembly, and confirm correct seating before test runs. Because this is an internal powerhead component, precise alignment and correct fastener torque will reduce the risk of early failure.

Consider the connecting rod a consumable service component — change it if runtime or a visual inspection shows signs of fatigue, and validate clearances after any rebuild to preserve consistent engine performance.
