Service Piston and Cylinder Liner Assembly for 61SH

The YS Engine YSS6205S replacement package is aimed at RC-scale 61SH glow engines, providing a piston, piston ring and cylinder liner to renew worn internal parts and improve cylinder sealing.

Intended for hobby maintenance, the set assists with mid-life engine refreshes on 61SH models. Before completing the rebuild, verify that the liner bore is round, confirm ring seating and inspect mating surfaces to promote reliable operation.

Fit this matched set when compression declines or oil usage rises; replacing piston, ring and liner together helps keep cylinder geometry consistent and stabilises engine running in RC models.

Will installing fresh internals affect running characteristics?

Installing new piston, ring and liner will usually restore lost compression and make the engine run more steadily, but it does not change core timing settings or the engine's original design output.

Can I just change the ring to save time?

While replacing only the ring can work if the piston and liner are in good condition, swapping the full matched set is recommended when wear is present to ensure correct sealing and longevity.

What checks should I do after fitting this kit?

After assembly, check compression, listen for unusual noises and inspect for oil leaks. A short running-in period under varying loads helps the ring bed into the liner.

Are these parts direct OEM replacements for 61SH?

The kit is specified for compatibility with 61SH engines and is intended to match the original running dimensions; it is an aftermarket replacement designed for hobby use.
