The Wacker Neuson Piston Ring is a genuine OEM piston ring designed for the RD24-100, RD27-120, RD28-120, and their C, O, and DPF variant tandem rollers. As a factory-sourced component, it meets the exact dimensional and material standards of the original part, ensuring it drops into place with no guesswork on fitment. This piston ring covers an extensive range of Wacker Neuson tandem roller configurations, including standard, combination, offset, and diesel particulate filter-equipped models across multiple production series. When you need the correct part the first time, the OEM designation on removes any doubt.
Key Features
- OEM Dimensional Accuracy — Manufactured to the original bore diameter and ring thickness tolerances, maintaining proper compression sealing and controlled oil consumption in the cylinder.
- Direct Drop-In Replacement — Matches the original piston groove profile exactly, requiring no re-machining or fitment adaptation during installation.
- Broad Tandem Roller Coverage — Compatible with RD24-100, RD27-120, and RD28-120 series tandem rollers, including standard, C (combination), O (offset), and DPF variants across multiple production generations.
- Compression Integrity Restored — A worn or broken piston ring causes loss of compression, increased oil consumption, and reduced engine output; replacing it with a correctly spec'd OEM ring restores full power and efficiency.
- Emission System Compatibility — Correct ring sealing is especially critical on DPF-equipped models, where blow-by from a worn ring can contaminate the aftertreatment system and trigger fault conditions.
A piston ring seals the combustion chamber between the piston and the cylinder wall, allowing the engine to build and hold the compression pressure needed for efficient combustion. It also regulates the thin film of oil on the cylinder wall, preventing excess oil from entering the combustion chamber and burning off. When a piston ring wears, cracks, or loses tension, compression drops, power output falls, oil consumption rises, and exhaust smoke increases — all signs that the ring needs immediate replacement to avoid further engine damage.
