The Wacker Neuson is a genuine OEM Piston Ring Set (0.25) designed for the CRT36-24A 915mm/36in ride-on concrete trowel series, the RD12A-90 tandem roller, and the BFS 2020AS floor saw. As a direct factory replacement, this 0.25mm oversize ring set is sourced from Wacker Neuson and manufactured to the same tolerances as the original engine components. Fitment extends across multiple CRT36-24A configurations — including standard, high-speed, wheel kit, and electric variants — as well as RD12A-90 models with foldable ROPS. Keeping the correct oversize specification on hand ensures the engine rebuild goes in right the first time without rework.
Key Features
- Oversize-Matched Ring Profile — Manufactured to the 0.25mm oversize specification, ensuring proper bore-to-ring clearance after cylinder honing and a consistent compression seal.
- Genuine OEM Sourcing — Supplied directly from Wacker Neuson, this set meets the same metallurgical and dimensional standards as the rings installed at the factory, preserving engine compression ratings.
- Broad Cross-Model Fitment — Confirmed compatible with CRT36-24A ride-on trowel variants, the RD12A-90 tandem roller, and the BFS 2020AS floor saw — covering multiple machine families from one part number.
- Compression and Oil Control — A correctly sealed ring set maintains cylinder pressure, protects against oil blow-by, and restores power output lost to a worn or damaged ring package.
- Engine Rebuild Confidence — Using the correct oversize ring during an engine overhaul prevents premature wear-in failure and avoids the cost of a repeat tear-down caused by mismatched ring sizing.
Piston rings seal the combustion chamber between the piston and the cylinder wall, controlling compression pressure and regulating oil consumption. A complete ring set typically includes compression rings to contain combustion gases and an oil control ring to scrape excess oil back down the cylinder bore. When rings wear out or break, the engine loses compression, burns oil, produces excessive smoke, and delivers reduced power — symptoms that worsen quickly and can lead to full engine failure if left unaddressed. The 0.25mm oversize designation means these rings are sized for a cylinder bore that has been machined slightly larger during reconditioning, making them a precision engine rebuild component rather than a routine service item.
