Replacement Connecting Rod for 61ST-H - YS Engine YSS7110  [YSS7110]

Connecting rod overview for 61ST-H

The YS Engine YSS7110 connecting rod is supplied as a replacement designed specifically for 61ST-H model engines. Its role is to convert piston reciprocation into crank rotation and it is intended as a direct service item when the original rod is worn or damaged.

Confirm the engine code reads 61ST-H before disassembly. Inspect the rod journals, bearings, and mating faces for scoring or play, renew any worn bearings, and assemble in a clean environment to keep contaminants out of the engine internals.

Used during routine maintenance and tuning, the connecting rod promotes steady piston-to-crank operation; correct reassembly is important to retain engine balance and consistent running characteristics. Supplied as a single spare component for model engine maintenance.
