The Wacker Neuson is a genuine OEM Spark Plug Terminal Cap designed for a wide range of Wacker Neuson floor saws and vibratory plate compactors. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component it replaces. Compatibility spans the BFS735 gasoline floor saw series, the WP1540A and WP1550A single-direction vibratory plates, and the VP1135A, VP1135Aw, and VP2050Aw vibratory plate families. Keeping this cap in good condition ensures a clean, consistent electrical connection at the spark plug — critical to reliable engine starting and smooth operation across all covered models.
Key Features
- Genuine OEM Electrical Integrity — Manufactured to Wacker Neuson's exact conductor and insulation specifications, ensuring correct voltage transfer to the spark plug without arcing or misfiring.
- Secure Snap-Fit Connection — Designed to seat firmly onto the spark plug terminal, maintaining a weatherproof seal and vibration-resistant contact — essential on high-frequency vibratory compaction equipment.
- Broad Model Coverage — Fits BFS735 floor saw models, WP1540A and WP1550A vibratory plates, and VP1135A and VP2050Aw series plates, covering a wide cross-section of Wacker Neuson gasoline-powered equipment.
- Supports Clean Engine Starting — A correctly seated terminal cap delivers a full, consistent spark, enabling confident cold and warm starts on both saws and compactors in demanding site conditions.
- Ignition Safety Compliance — Proper insulation on the terminal cap prevents unintended electrical discharge and protects operators during routine spark plug servicing and inspection.
The spark plug terminal cap is the connector that joins the ignition wire to the top of the spark plug, completing the high-voltage circuit that ignites the air-fuel mixture in the engine cylinder. It provides both an electrical connection and mechanical retention, holding the ignition lead securely in place even under the constant vibration produced by plate compactors and floor saws. When the cap cracks, loosens, or loses its internal contact, the engine may misfire, run erratically, or fail to start — making it a small part with a significant impact on machine uptime.
