Wacker Neuson 5000099336 Cylinder Kit with Piston

The Wacker Neuson Cylinder Kit with Piston is a genuine OEM engine rebuild assembly designed for the BS-series gasoline vibratory rammer lineup, including the BS50, BS60, BS65, BS70, BS500, BS600, BS650, and BS700 families. As a direct OEM replacement, this kit is manufactured to the same specifications as the original components installed at the factory, ensuring a correct fit within the engine bore without the guesswork of sourcing cylinder and piston components separately. The covers an exceptionally wide range of BS rammer variants — including standard, oil-injected, variable speed, and high-altitude configurations — making it the go-to rebuild solution across Wacker Neuson's rammer fleet. When your rammer shows signs of power loss, excessive smoke, or increased fuel consumption, replacing the cylinder and piston assembly restores full compression and engine output.

Key Features

• Matched Cylinder-to-Piston Tolerancing — Cylinder bore and piston diameter are manufactured as a matched set, ensuring correct compression sealing from the first pull of the recoil.
• Genuine OEM Construction — Sourced directly through Wacker Neuson's OEM supply chain, this kit meets the same material and dimensional standards as the parts originally installed in the rammer at the time of manufacture.
• Broad BS-Series Compatibility — Fits a wide range of BS50, BS60, BS65, BS70, BS500, BS600, BS650, and BS700 rammer models including standard, oil-injected, variable speed, and high-altitude variants.
• Restores Full Engine Compression — A worn cylinder or piston causes loss of compression, weak impact force, hard starting, and excessive oil or fuel burn; this kit brings compression back to operating specification.
• Complete Assembly in One Part Number — Cylinder and piston are supplied together under a single part number, simplifying the parts ordering process for field technicians and service shops.
• Engine Safety and Emissions Compliance — Correct piston-to-cylinder clearance is critical to preventing seizure and controlling exhaust emissions; using the OEM-spec assembly keeps the engine operating within its designed parameters.

The cylinder and piston assembly form the core of the two-stroke engine that drives a vibratory rammer's impact mechanism. The piston moves up and down within the cylinder bore, compressing the air-fuel mixture to generate the combustion force that drives the rammer's foot downward and compacts cohesive soils in trenches and tight spaces. Over time, the cylinder bore can wear, score, or develop micro-cracks, and the piston rings and skirt wear down alongside it — both conditions reduce compression, rob the rammer of impact energy, and cause hard starting or rough running. Replacing the cylinder and piston together as a kit ensures the bore-to-piston clearance is correct from the outset, restoring the engine to its designed output and preventing premature failure of the new components.
