The Wacker Neuson Crankshaft with Compensating Volume is a genuine OEM component designed for BS62-2 and BS68-2 series rammers, including Sunbelt-configured models. As a direct Wacker Neuson OEM part, the is manufactured to the exact specifications your machine was built with, ensuring proper fit and function without guesswork. Compatibility spans multiple BS62-2 and BS68-2 variants — including the BS62-2b, BS62-2lb, BS62-2/25, BS68-2b, and BS68-2/28 — making this a versatile service part for fleets running these rammer series.
Key Features
- OEM-Matched Crankshaft Geometry — Manufactured to the precise stroke dimensions and journal tolerances required by Wacker Neuson BS-series rammer engines, ensuring correct timing and compression cycle performance.
- Integrated Compensating Volume — The built-in compensating volume is part of the rammer's two-cycle scavenging system; this assembly delivers the correct displacement balance needed for consistent power output.
- Drop-In Engine Compatibility — Engineered to mate directly with the existing engine cases and bearing seats on compatible BS62-2 and BS68-2 series rammers, including standard and Sunbelt variants.
- Broad BS-Series Fitment — Covers BS62-2b, BS62-2lb, BS62-2/25, BS62-2/28, BS68-2b, and BS68-2/28 models, including Sunbelt-configured rammers, from a single part number.
- Sustained Compaction Force — A correctly fitted crankshaft maintains the impact frequency and stroke energy your rammer is rated for; a worn or damaged crank causes erratic ramming cycles and loss of compaction effectiveness.
The crankshaft is the central rotating component of the rammer's two-stroke engine, converting the linear motion of the piston into the rotational force that drives the machine's ramming mechanism. On Wacker Neuson BS-series rammers, the crankshaft also incorporates a compensating volume — a chamber that works with the engine's reed valve and scavenging ports to control the air-fuel charge during each cycle, which is critical to maintaining consistent stroke energy at the foot. When the crankshaft wears or fails, the engine loses compression integrity, ramming frequency drops off, and the machine can no longer deliver reliable soil compaction — making timely replacement essential to keeping the rammer working as specified.
