The Wacker Neuson Fly Wheel is a genuine OEM component designed for BPS1550B, BPS1550Bw, BPS2050B, BPS2050Bw, and A5000/160B series equipment. As a factory-sourced part, it is manufactured to the exact tolerances and balance specifications required by the original design, ensuring a direct, correct-fit installation with no guesswork. This fly wheel is the right choice when you need confidence that the replacement part matches what came off the machine. Verify your model number against the fitment list before ordering to confirm compatibility.
Key Features
- OEM-Balanced Construction — Manufactured to the precise rotational balance and mass specifications of the original, preventing vibration irregularities that can stress the engine over time.
- Direct-Fit Installation — Engineered to bolt up to the crankshaft and ignition trigger components exactly as the original, with correct keyway alignment and bolt pattern.
- Broad BPS and A-Series Fitment — Confirmed compatibility across BPS1550B, BPS1550Bw, BPS2050B, BPS2050Bw, and A5000/160B models, covering a range of Wacker Neuson pump and power unit applications.
- Consistent Engine Timing — A correctly functioning fly wheel maintains steady ignition trigger timing; a worn or damaged unit can cause misfires, hard starting, or erratic engine behavior.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, carrying the same part number — 5100067156 — used by authorized service centers worldwide.
The fly wheel is a heavy rotating disc mounted directly to the engine crankshaft. Its primary job is to store rotational energy during the power stroke and release it smoothly through the remaining engine cycles, keeping the crankshaft turning steadily between firing events. On most small engines, the fly wheel also carries the magnets that trigger the ignition system, making its condition and correct installation critical to reliable starting and consistent engine timing. A fly wheel that is cracked, out of balance, or has damaged magnet pockets will cause ignition problems, rough running, or complete failure to start.
