The Wacker Neuson Rotary Shaft Seal is a genuine OEM component designed for the BH 22, BH 23, BH 24, BH 55, and BH 65 series gasoline breakers. As a direct OEM replacement, part is manufactured to the same specifications as the original, ensuring a proper fit within the crankshaft or drive shaft assembly of these gas-powered demolition tools. This seal is compatible across a broad range of BH-series configurations including standard, Low Vibration, RS, and rw variants. Sourcing the correct OEM part is critical on high-vibration equipment like breakers, where seal integrity directly affects engine longevity and tool performance.
Key Features
- OEM-Grade Sealing Material — Manufactured to original equipment tolerances, delivering the correct compression and material grade needed to withstand the high-rpm, high-vibration operating environment of gasoline breakers.
- Drop-In Shaft Replacement — Engineered to seat correctly on the shaft journal without rework, maintaining proper contact with the shaft surface to prevent oil migration past the seal lip.
- Broad BH-Series Coverage — A single part number covers BH 22, BH 23, BH 24, BH 55, and BH 65 gasoline breakers across standard, Low Vibration, RS, and rw variants, simplifying parts stocking for multi-unit fleets.
- Protects Engine Internals — A functioning rotary shaft seal keeps crankcase oil contained and contaminants out; a worn seal leads to oil leaks, accelerated internal wear, and eventual engine failure on demanding demolition applications.
- Genuine Wacker Neuson OEM Part — Supplied directly in the Wacker Neuson parts chain, so the part number, geometry, and material specification match what was installed at the factory.
A rotary shaft seal sits at the point where a rotating shaft exits the engine or gearbox housing, creating a dynamic barrier between moving and stationary components. Its primary job is to retain lubricating oil inside the crankcase while blocking dust, debris, and moisture from entering — conditions that are especially severe on a gasoline-powered demolition breaker operating in concrete dust and grit. When the seal lip wears, hardens, or tears, oil loss begins, lubrication to critical internal components drops, and abrasive contamination can accelerate damage to bearings and the crankshaft itself.
