YS Engine YSR6109 Connecting Rod (.61) — RC engine conrod spare  [YSR6109]

Replacement Connecting Rod for .61-Class RC Engines

The YS Engine YSR6109 Connecting Rod 61 is a direct-replacement conrod made as a spare for RC-scale engines. It links piston and crankshaft and is intended for routine maintenance and rebuilds on .61-class model engines that need a like-for-like replacement.

This single component is provided for engine servicing, with attention to correct dimensions and heat treatment so it endures normal operating loads in glow model engines. It is not a tuning part; its value is in restoring reliable mechanical function after internal work.

Installation notes: check mating surfaces and bearing condition prior to fitting, follow the engine manufacturer's torque and clearance recommendations, and renew associated fasteners and bearings if wear is evident. Confirm compatibility with your engine by referencing the part name and model number.
