The Wacker Neuson Set of Piston Rings 0.25 is a genuine OEM set of piston rings 0.25 designed for LTN4Y and LTN5Y series light towers, including the LTN4Y, LTN4Y 60 Hz, LTN4Y SA, LTN4Y RH, LTN4Y 120V/60Hz, LTN5Y, LTN5Y SA, LTN5Y CH, LTN5Y UK, LTN5Yp, LTN5Yp HD, LTN5Ypa, and LTN5Ypk models. As a direct Wacker Neuson OEM part, is manufactured to the same specification as the original component, ensuring a drop-in fit with no guesswork on sizing or compatibility. This oversize 0.25 ring set is the correct service replacement when rebuilding a worn engine on these light tower models.
Key Features
- OEM Ring Geometry and Sizing — Manufactured to Wacker Neuson's exact oversize 0.25 specification, ensuring correct ring-to-bore clearance and proper seating in the cylinder wall.
- Direct Engine Rebuild Fit — Designed as a drop-in replacement during engine overhaul on LTN4Y and LTN5Y series light towers, matching the original ring groove dimensions without additional machining beyond the 0.25 oversize bore.
- Broad LTN Series Compatibility — Covers a wide range of LTN4Y and LTN5Y variants including SA, RH, 60 Hz, 120V/60Hz, CH, UK, Yp, Yp HD, Ypa, and Ypk configurations.
- Restored Compression and Oil Control — Worn piston rings cause loss of compression, increased oil consumption, and reduced generator output; a correct-spec replacement ring set restores engine sealing and power delivery.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, carrying the same part number 5100075822 used in factory service documentation for full traceability.
Piston rings seal the combustion chamber between the piston and the cylinder wall, maintaining compression and preventing oil from entering the combustion zone. They play a critical role in engine efficiency — when rings wear, blow-by gases reduce power output, fuel consumption rises, and oil smoke becomes visible from the exhaust. Replacing the piston rings with a correctly sized oversize set during an engine rebuild restores compression to specification and extends the service life of the rebuilt engine.
