Wacker Neuson 86312 Ring Seal

The Wacker Neuson 86312 is a genuine OEM Ring Seal designed for the BS-series vibratory rammer lineup, including BS50-2, BS50-2i, BS60-2, BS60-2i, BS70-2, BS70-2i, BS50-4s, BS60-4s, BS50-4As, BS60-4As, BS70-4As families, as well as select WP1540 and WP1550 single-direction vibratory plates. As a factory-sourced Wacker Neuson component, part 86312 is manufactured to the exact material and dimensional tolerances of the original, ensuring a seamless drop-in installation. This Ring Seal is a critical sealing component that prevents fluid migration and contamination ingress within the rammer's internal assemblies, directly affecting the long-term integrity of your machine. Cross-reference your model number before ordering — the 86312 spans an exceptionally wide range of BS rammer variants across multiple generations and shoe configurations.

Key Features

• Genuine OEM Material Grade — Manufactured from the same sealing compound specified at the factory, delivering the correct compression set and chemical resistance for two-cycle oil, four-cycle oil, and fuel contact environments found in BS-series rammers.
• Exact Dimensional Match — The 86312 installs directly into the original seal groove without trimming, stretching, or shimming, maintaining the designed interference fit and sealing load on installation.
• Broad Multi-Generation Fitment — Verified across BS50, BS60, BS70 rammer families (two-cycle, four-cycle, oil-injected, and battery-assisted variants) as well as WP1540 and WP1550 vibratory plate models.
• Prevents Contamination-Driven Wear — A degraded or missing ring seal allows dirt, moisture, and debris into precision internal bores, accelerating wear on pistons, bearings, and crankshaft components. Replacing 86312 at the first sign of seepage keeps those surfaces protected.
• Fuel and Oil System Integrity — In fuel-side or oil-side applications, a correctly seated Ring Seal is essential for maintaining system pressure and preventing hazardous leaks — making timely replacement both a performance and a safety consideration.

A ring seal is a precision-formed elastomeric or composite sealing element that fills the gap between two mating surfaces or the space around a moving shaft to prevent the passage of fluids, gases, or contaminants. In vibratory rammers, ring seals are used at critical junctions in the fuel system, lubrication circuit, and internal drive assembly to maintain pressure boundaries and keep abrasive particles out of machined surfaces. When a ring seal hardens, cracks, or takes a permanent set over time, leaks develop that can starve lubrication points, allow fuel to migrate where it should not, or introduce grit into bearing surfaces — any of which will accelerate internal wear and ultimately lead to costly component damage if left unaddressed.
