Key Features
- Genuine OEM Ring Tolerances — Manufactured to exact bore clearance and ring gap specifications for this 0.50mm oversize application, ensuring correct compression sealing from day one.
- Oversize Rebuild Fitment — Designed for engines that have been bored to the 0.50mm oversize spec; drops into the cylinder as part of a standard piston and ring overhaul without additional machining to the ring itself.
- Broad Model Compatibility — Fits MRH800GS walk-behind rollers, SP118 and SP1CE13H18 flat saws, and WM120 and EM120 series mixers, making it a practical stocking part for multi-equipment fleets.
- Restores Engine Compression — Worn or broken piston rings allow combustion gases to blow past the piston, robbing the engine of power and increasing oil consumption. A fresh ring set restores proper cylinder sealing and full engine output.
- Fuel System Integrity — Correct ring seating prevents oil from entering the combustion chamber, protecting the carburetor and exhaust system from oil fouling during extended operation.
Piston rings seal the gap between the piston and the cylinder wall, maintaining combustion pressure while preventing engine oil from being burned in the combustion chamber. There are typically compression rings, which trap the expanding combustion gases to drive the piston down, and an oil control ring, which scrapes excess oil back down the cylinder wall. When rings wear, lose tension, or break, the engine loses compression, produces excessive smoke, burns through oil rapidly, and struggles to develop full power. Replacing the ring set with a correctly sized OEM set restores the engine to proper operating condition and extends the service life of the rebuild.
