The Wacker Neuson Piston Ring Set is a genuine OEM component designed for the CRT48-25K-L, CRT48-25K-H, and CRT36-25K-H ride-on concrete trowels. As a factory-sourced assembly, this set meets the exact material and dimensional specifications required by Wacker Neuson for the engine assemblies found in these machines. It covers both the 1220mm/48in and 915mm/36in ride-on trowel configurations, making it the correct choice across low-speed and high-speed CRT variants. Verify your model number before ordering to confirm fitment.
Key Features
- Genuine OEM Ring Geometry — Sourced directly from Wacker Neuson, this piston ring set is manufactured to the exact bore tolerances and ring gap specifications required for the CRT engine assemblies, ensuring proper compression seal and oil control.
- Complete Set for Full Overhaul — Supplied as a matched set, the 5000154805 includes all rings needed for a full piston service interval so all rings are replaced together as designed.
- Fits Multiple CRT Models — Compatible with the CRT48-25K-L low-speed, CRT48-25K-H high-speed, and CRT36-25K-H high-speed ride-on trowels, spanning both 48in and 36in platform sizes.
- Restores Engine Compression — Worn or broken piston rings cause loss of compression, increased oil consumption, and power drop — a fresh ring set brings combustion performance back to spec so the trowel maintains consistent rotor speed under load.
- Correct Fit for Engine Reassembly — OEM-matched ring dimensions drop into the existing piston grooves without the need for machining or shimming, supporting a straightforward engine rebuild process.
Piston rings form a dynamic seal between the piston and the cylinder wall inside the engine. They serve two critical roles: retaining combustion pressure above the piston to generate power, and controlling how much oil contacts the cylinder wall to prevent excessive consumption or fouling. As rings wear over time, the seal degrades — leading to reduced power output, harder starting, increased exhaust smoke, and oil burning. Replacing the ring set during an engine overhaul restores proper compression and oil control, bringing the engine back to the output levels the ride-on trowel depends on for consistent finishing performance across a full concrete pour.
