Wacker Neuson 5100016693 Piston Complete

The Wacker Neuson Piston Complete is a genuine OEM component designed for the DPU80, DPU90, and DPU110 series reversible and forward-moving vibratory plate compactors. Sourced directly from Wacker Neuson, this assembly carries the same part number and tolerances as the original, ensuring a correct fit inside the engine without guesswork. It covers an extensive range of configurations across the DPU80Lec, DPU80Lem, DPU90Lec, DPU90Lem, DPU110Lec, and DPU110Lem model families, including US-market variants and KMAT configurations. When you need to restore engine compression and performance to a Wacker Neuson vibratory plate, part number is the verified OEM solution.

Key Features

• OEM-Spec Bore Tolerancing — Manufactured to exact bore and ring-groove dimensions, maintaining correct compression ratios and oil-control performance in the engine cylinder.
• Drop-In Engine Fit — Matches the original piston assembly configuration, allowing direct installation without machining or adapter components.
• Broad DPU Series Coverage — Compatible with DPU80, DPU90, and DPU110 plate compactor families, including reversible (r) variants, Lec, Lem, and US-market models.
• Full Compression Restoration — A worn or damaged piston causes hard starting, power loss, and excessive oil consumption; replacing it with a correctly sized OEM assembly restores full engine output and smooth operation.
• Genuine Wacker Neuson Part — Supplied as an authorized OEM assembly under part number 5100016693, meeting the same material and dimensional standards as the part originally installed at the factory.

The piston is the reciprocating heart of a four-stroke engine — it compresses the air-fuel mixture, transfers combustion force to the crankshaft via the connecting rod, and helps regulate oil consumption through its ring pack. In a vibratory plate compactor, the engine works under sustained load, and piston wear or damage directly reduces compression pressure, leading to hard starts, loss of compaction force, and increased fuel consumption. Replacing a worn piston complete assembly restores correct cylinder pressure, allowing the engine to produce its rated power and keep the plate delivering consistent compaction performance across the job.
