The Wacker Neuson Piston is a genuine OEM Piston designed for a broad range of Wacker Neuson vibratory plate compactors, including the BPU2540A, WP1540A, WP1550A, VP1340A, VP1550A, VP2050A, BPS1550A, BPS2050A series, and their variants. Sourced directly from Wacker Neuson, this part meets the original engineering standards for the engine assembly it serves. With coverage spanning dozens of model configurations — including US, CN, and Loxam variants — part number is the correct OEM replacement across the full WP, VP, BPU, and BPS plate compactor families.
Key Features
- OEM Dimensional Accuracy — Manufactured to Wacker Neuson's original bore tolerances, ensuring proper compression seal and ring land geometry specific to this engine application.
- Direct Drop-In Replacement — Engineered to install using standard piston assembly procedures with no re-machining or bore modification needed for compatible models.
- Broad Vibratory Plate Coverage — Fits BPU2540A, WP1540A, WP1550A, VP1340A, VP1550A, VP2050A, BPS1550A, BPS2050A, and related model variants across multiple production series.
- Compression Integrity Restored — A worn or damaged piston causes loss of engine compression, hard starting, and reduced compaction output; replacing with 5100019661 restores full power delivery to the exciter system.
- Genuine Wacker Neuson OEM Part — Supplied as an authorized OEM component, ensuring material grade and piston weight match the original specification for balanced engine operation.
The piston is a core reciprocating component inside the engine cylinder, converting combustion pressure into the crankshaft rotation that ultimately drives the vibratory mechanism of the plate compactor. It works in conjunction with the piston rings and connecting rod to maintain compression and transfer power efficiently. When a piston wears, cracks, or becomes scored, the engine loses compression, consumes excess oil, and may fail to develop the power needed to drive the compaction plate effectively.
