The Wacker Neuson 108125 Cylinder Complete is a genuine OEM component designed for the PT2A self-priming trash pump series, the BPU2540A reversible vibratory plate compactor, and a wide range of VP and WP single-direction vibratory plate compactors. As a factory-sourced part, the 108125 is manufactured to the exact tolerances specified for these machines, ensuring a direct, like-for-like installation with no guesswork. This cylinder assembly is a core engine component, and using the correct OEM replacement is essential to maintaining power output, compression integrity, and long-term engine reliability across all compatible models. Whether you are servicing a PT2A pump or a VP1340A, VP1550A, VP2050A, WP1540A, or WP1550A plate compactor, part number 108125 is the verified replacement.
Key Features
- Genuine OEM Compression Integrity — Manufactured to Wacker Neuson's exact bore tolerances, this cylinder assembly maintains the compression ratio the engine was designed to run at — critical for consistent starting and full power delivery.
- Direct Drop-In Replacement — The 108125 matches the original mounting configuration and porting layout, so it installs into compatible engines without additional machining or adaptation.
- Broad Fitment Across VP, WP, BPU, and PT2A Equipment — Confirmed compatibility with PT2A trash pumps, BPU2540A reversible plate compactors, and VP1340A, VP1550A, VP2050A, WP1540A, and WP1550A vibratory plate compactors.
- Restores Engine Performance — A worn or scored cylinder causes loss of compression, hard starting, excessive oil consumption, and reduced centrifugal force output in plate compactors — replacing it with 108125 brings the engine back to design operating condition.
- Fuel System Safety Compliance — A properly seated cylinder with correct compression prevents unburned fuel from passing into the crankcase, reducing the risk of oil contamination and crankcase pressure buildup.
The cylinder is the central chamber of a small gasoline engine where the air-fuel mixture is compressed and combustion occurs. The piston travels up and down inside the cylinder bore, and the tight clearance between the two is what generates compression — the key to reliable starting and efficient power transfer. When the cylinder bore becomes worn, scored, or damaged, compression drops, causing hard starts, loss of power, and increased fuel consumption. In vibratory plate compactors, this directly reduces the centrifugal force delivered to the baseplate, compromising compaction depth and consistency. Replacing a worn cylinder with the correct OEM part restores the engine to its intended compression spec and puts the machine back to full working condition.
