The Wacker Neuson is a genuine OEM set of Oversize Piston Rings 0.50mm designed for a broad range of Wacker Neuson equipment including VP and WP series single-direction vibratory plate compactors, PT2 trash pumps, CT36-6 concrete trowels, BFS floor saws, and GPi3200 and GPSi3200 portable inverter generators. As a direct factory replacement, is manufactured to the same dimensional and material specifications as the original rings installed at the factory, ensuring a correct fit in the bore after a 0.50mm oversize rebore. This is the part to specify during engine reconditioning whenever the cylinder bore has been honed or machined to the first oversize, restoring compression and oil control to like-new condition across all applicable models.
Key Features
- Oversize Bore Compatibility: — Ground to 0.50mm over standard diameter, these rings are sized specifically for cylinders that have been rebored to the first oversize — they will not fit a standard bore.
- Genuine OEM Specification: — Manufactured by Wacker Neuson as a factory original part, matching the original ring width, gap tolerance, and ring-face coating for correct sealing pressure against the cylinder wall.
- Wide Cross-Model Fitment: — Confirmed for VP and WP vibratory plate compactors, PT2 trash pumps, CT36-6 trowels, BFS floor saws, and GPi3200/GPSi3200 generators — one part number covering a broad engine family.
- Compression and Oil Control Restored: — Worn or broken piston rings cause blow-by, oil consumption, hard starting, and loss of power; correctly sized oversize rings restore cylinder seal and return the engine to full output.
- Engine Rebuild Confidence: — Using the correct OEM oversize ring set during a top-end rebuild ensures the ring-to-wall clearance stays within the engine manufacturer's specification, protecting the investment in the rebore.
Piston rings seal the combustion chamber between the piston and the cylinder wall, maintaining the compression pressure needed for efficient combustion while also controlling how much oil reaches the combustion chamber. A correctly functioning ring pack keeps blow-by gases out of the crankcase, holds oil consumption to a minimum, and allows the engine to develop its rated power. When rings wear, stick, or break, compression drops, oil burns off, and the engine may smoke heavily, run rough, or fail to start. Oversize rings like the Wacker Neuson 5000164789 are fitted during engine reconditioning after the cylinder bore has been machined to remove wear and restore a true, round surface — the extra 0.50mm of material compensates for the metal removed during that process.
