YS Engine YSR6109 Connecting Rod 61 — Replacement for RC Engines  [YSR6109]

Durable Conrod for .61 Engines

The YS Engine YSR6109 Connecting Rod 61 is produced as a drop-in style conrod replacement for RC model engines. It transmits motion between piston and crank and is intended for use during rebuilds or when replacing a worn conrod on .61-class engines.

Offered as a single spare, the component emphasises correct dimensions and heat treatment to resist normal in-service loads in glow engines. It should be regarded as a maintenance part rather than a tuning modification.

Installation guidance: inspect journals and bearings before assembly, follow the original engine maker's torque and clearance advice, and renew associated fasteners and bearings when wear is suspected. Verify the part against the YSR6109 number to ensure compatibility.
