The Wacker Neuson Piston Pin is a genuine OEM component designed for a wide range of Wacker Neuson rammer and compactor models, including the BS50, BS60, BS70, BS62, BS65, BS68, BS72, AS50e, AS60e, AS62e, AS68e, AS62ve, AS68ve, and DS70 series. As a direct OEM replacement, this piston pin is sourced through Wacker Neuson's authorized parts program, ensuring it meets the original design specification for your machine. Whether you're servicing a two-stroke or four-stroke rammer, part number covers an extensive range of serial configurations across both US and international variants. Keeping this critical internal engine component in serviceable condition is essential to maintaining consistent compaction performance on the job.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the exact diameter and surface finish tolerances required for proper wrist pin-to-piston and pin-to-connecting-rod fit, preventing internal engine slop or accelerated bore wear.
- Drop-In Engine Replacement — Engineered to install directly into the piston and connecting rod assembly without machining or fitting adjustments, using the same retention method as the original component.
- Broad Rammer Series Coverage — Compatible with BS50, BS60, BS65, BS68, BS70, BS72, BS62 rammers, AS50e, AS60e, AS62e, AS62ve, AS68e, AS68ve electric rammers, and DS70 trench rammers across multiple production variants.
- Restored Power Stroke Integrity — A worn or damaged piston pin allows lateral movement inside the piston boss, causing knock, loss of compression, and uneven compaction force; replacing it restores the full, consistent impact stroke the machine is built to deliver.
- Hardened Construction for High-Cycle Loads — The piston pin operates under high-frequency reciprocating loads inside a rammer engine; the OEM-spec material hardness and surface treatment are matched to withstand these repeated impact forces across a full service life.
The piston pin — also called a wrist pin — connects the piston to the small end of the connecting rod, allowing the rod to pivot as the piston moves up and down inside the cylinder bore. In a rammer engine, this pin endures high-frequency reciprocating loads with every compaction stroke, making material integrity and dimensional accuracy critical. When the pin wears, becomes scored, or develops excessive clearance in the piston bosses, the result is audible knock, loss of compression, and degraded impact energy delivered to the rammer foot — leading to poor compaction and potential further engine damage if left unaddressed.
