Wacker Neuson 5100000358 Set of Piston Rings

The Wacker Neuson Set of Piston Rings is a genuine OEM component designed for a broad range of Wacker Neuson equipment, including GV7000A and GV7003A portable generators, GP5600A and GP6600A generators, BFS 1318, BFS 1345, and BFS 1350 series gasoline floor saws, BPU 5545A and BPU 5260Ah and BPU 6275Ah reversible vibratory plate compactors. Sourced directly from Wacker Neuson, this set meets the exact tolerances specified for the original engine build — ensuring the rings seat and seal correctly without any guesswork. If your machine is showing signs of increased oil consumption, reduced compression, or loss of power, worn piston rings are a likely culprit, and part number is the correct OEM replacement to restore engine performance. Keep one on hand as a scheduled maintenance item for any high-hour engine in your fleet.

Key Features

• OEM Compression and Oil-Control Spec — Rings are manufactured to the exact radial thickness, gap clearance, and tension profile specified for Wacker Neuson engines, ensuring correct compression and oil film control from the first start-up.
• Complete Set Included — Supplies all rings required for a full piston rebuild in a single kit, so technicians have everything needed for a thorough engine overhaul without sourcing individual rings separately.
• Drop-In Engine Fitment — Engineered to install directly into the existing cylinder bore on compatible engines; no machining or custom fitting required when replacing like-for-like on a correctly maintained engine.
• Wide Cross-Equipment Compatibility — Fits GV and GP series portable generators, BFS gasoline floor saws, and BPU reversible vibratory plate compactors — one part number that spans multiple machine families sharing the same engine platform.
• Restores Lost Compression and Power — A worn ring set allows blow-by gases to bypass the piston, robbing the engine of compression. Installing a fresh 5100000358 set restores combustion efficiency and brings power output back to spec.
• Fuel and Emissions Integrity — Correctly sealing piston rings prevent unburned fuel and oil from entering the combustion chamber excessively, keeping the engine running clean and within expected fuel consumption ranges.

Piston rings form the critical seal between the piston and the cylinder wall inside a four-stroke engine. They serve two roles: compression rings trap combustion pressure above the piston to drive the power stroke, while oil control rings scrape excess lubricant off the cylinder wall and return it to the sump. When rings wear, lose tension, or break, compression drops, oil burns off into the combustion chamber, and the engine produces visible smoke, consumes more fuel, and loses the power needed to drive the machine effectively. Replacing the full Set of Piston Rings — part 5100000358 — during an engine rebuild or at the first sign of ring-related symptoms is the most direct way to return the engine to its original operating condition.
