The Wacker Neuson 5000114802 is a genuine OEM Spark Plug designed for the BS-series gasoline vibratory rammer lineup, including the BS500, BS500-oi, BS60-2 EU, BS600, BS600-oi, BS650, BS700, and BS700-oi models. As a direct OEM replacement sourced through Wacker Neuson's authorized parts program, the 5000114802 meets the exact ignition specifications the engine was built around — no guesswork on heat range, thread pitch, or electrode gap. Keeping a fresh spark plug in your rammer is one of the simplest ways to maintain consistent starts, smooth power stroke cycles, and efficient fuel combustion across every compaction pass.
Key Features
- Correct Heat Range for Rammer Engines — Matched to the thermal demands of BS-series two-stroke and four-stroke rammer engines, ensuring the electrode operates within its designed temperature window for clean, consistent firing.
- Genuine OEM Component — Supplied as an authorized Wacker Neuson OEM part, this spark plug carries the same specification as the unit installed at the factory, so ignition timing and combustion efficiency are not compromised.
- Drop-In Thread and Reach Compatibility — The 5000114802 installs directly into the cylinder head of compatible BS-series rammers with no thread chasing or adapter required.
- Broad BS-Series Coverage — Fits the BS500, BS500-oi, BS60-2 EU, BS600, BS600-oi, BS650, BS700, and BS700-oi gasoline rammers, making it a practical stock item for crews running multiple Wacker Neuson jumping jacks.
- Ignition Reliability Under Hard-Start Conditions — A worn or fouled spark plug is a leading cause of hard starts and misfires in rammer engines. Replacing with a correctly specified OEM plug restores crisp ignition and prevents incomplete combustion that can load up the engine with carbon deposits.
The spark plug is the final link in the ignition chain — it delivers the high-voltage arc that ignites the air-fuel mixture inside the cylinder, driving the piston and powering the rammer's compaction stroke. In a vibratory rammer like the BS-series, the engine operates under repeated load cycles and is exposed to dust, vibration, and temperature swings that accelerate electrode wear and deposit buildup. A degraded spark plug causes misfires, rough idling, hard starting, and reduced compaction output; in severe cases it can lead to unburned fuel washing the cylinder walls and damaging piston rings. Replacing the spark plug at the manufacturer's recommended service interval — or any time starting performance deteriorates — is one of the most cost-effective maintenance steps an operator can take.
