The Wacker Neuson Piston Ring is a genuine OEM Piston Ring designed for CRT48-25K-L, CRT48-25K-H, and CRT36-25K-H ride-on concrete trowels. As a direct factory replacement, this part is manufactured to the same specifications as the original component, ensuring a correct fit within the engine assembly. It is compatible with both the 1220mm/48in and 915mm/36in ride-on trowel configurations across the CRT series lineup.
Key Features
- Genuine OEM Compression Integrity — Manufactured to original tolerances, maintaining the correct bore-to-ring clearance critical for consistent engine compression in ride-on trowel applications.
- Direct Engine Drop-In — Engineered to seat correctly within the cylinder bore of the CRT series engine, aligning with existing piston grooves without additional machining or fitting.
- Broad CRT Series Coverage — Fits the CRT48-25K-L (1220mm/48in Low Speed), CRT48-25K-H (1220mm/48in High Speed), and CRT36-25K-H (915mm/36in High Speed) ride-on trowels.
- Sustained Engine Output — A properly seated piston ring keeps combustion gases sealed above the piston, preserving the power output your trowel needs to deliver a consistent, high-quality concrete finish.
- Fuel and Oil Efficiency — Correct ring tension prevents oil from migrating into the combustion chamber and combustion gases from blowing past the piston, keeping fuel consumption and oil usage in check.
The piston ring forms a dynamic seal between the piston and the cylinder wall, preventing combustion gases from escaping into the crankcase while also controlling the thin film of oil that lubricates the cylinder bore. In a ride-on concrete trowel engine, where consistent power delivery directly affects the quality of the finished slab, a worn or broken piston ring causes a drop in compression, increased oil consumption, and rough running — all of which compromise both machine performance and the concrete finish. Replacing a worn ring promptly with the correct OEM part restores engine compression and oil control, extending the service life of the engine.
