The Wacker Neuson Ignition Coil is a genuine OEM ignition coil designed for a wide range of Wacker Neuson equipment, including CT36-9 and CT48-9 walk-behind concrete power trowels, PT3 trash pumps, GP4000 and GPi4300 portable generators, BFS and BFSX floor saws, and BPU 3050 reversible vibratory plate compactors. As a direct OEM replacement, this coil is manufactured to the same specifications as the original, ensuring correct output and a drop-in fit with no improvised solutions needed. Confirm your model number against the fitment list before ordering — this coil spans multiple machine families, so matching your specific model is the best way to get the right part the first time.
Key Features
- OEM-Spec Ignition Output: — Engineered to deliver the correct spark voltage and timing curve required by the original engine, ensuring reliable ignition across all compatible models.
- Broad Cross-Family Fitment: — Covers CT36-9 and CT48-9 concrete trowels, PT3 trash pumps, GP4000 and GPi4300 generators, BFS and BFSX floor saws, and BPU 3050 plate compactors.
- Direct Drop-In Replacement: — Mounts using the original mounting points and connects to existing wiring without adaptation, matching the physical profile of the factory coil.
- Prevents Hard-Start and Misfire Issues: — A worn or failed ignition coil causes hard starting, rough running, or complete no-start conditions; replacing with a correctly specified coil restores normal engine behavior.
- Fuel System Safety Relevance: — A properly functioning ignition coil prevents incomplete combustion and raw fuel discharge, which is especially important on equipment operating near flammable materials or in enclosed spaces.
- Genuine Wacker Neuson Part: — Supplied as genuine OEM, backed by Wacker Neuson's part quality standards and traceable to part number 5000156643 for accurate ordering and service records.
The ignition coil generates the high-voltage electrical pulse that fires the spark plug at precisely the right moment in the engine's combustion cycle. Without a functioning coil, the engine receives no spark and will not start or will run intermittently and with reduced power. Over time, the coil's internal windings can degrade from heat cycling and vibration, leading to weak spark output, increased fuel consumption, and eventual engine failure to start — replacing the coil restores the ignition system to its designed operating condition.
