The Wacker Neuson Flywheel is a genuine OEM component designed for the WP1550RW and WP1550R vibratory plate compactors and the PT2R centrifugal trash pump. As a direct Wacker Neuson OEM part, the is manufactured to the same specification as the original, ensuring a correct, no-hassle installation. This flywheel is a verified match for the WP1550 series plates and PT2R pumps, giving you confidence that you are ordering the right part the first time.
Key Features
- Genuine OEM Casting and Balance Spec — Manufactured by Wacker Neuson to the original rotational balance tolerances, maintaining smooth engine operation and preventing vibration-induced wear.
- Direct Drop-In Replacement — Matches the original mounting interface and keyway alignment, so the 5000084405 installs directly onto the crankshaft without machining or adaptation.
- Confirmed Fitment Across Two Machine Families — Compatible with the WP1550RW and WP1550R 15 kN vibratory plate compactors and the PT2R 2-inch centrifugal trash pump.
- Sustained Power Transfer — A correctly seated flywheel stores and delivers rotational energy evenly; a worn or cracked flywheel causes misfires, rough running, and loss of output in both compaction and pumping applications.
- Ignition System Integrity — On small-engine equipment, the flywheel carries the magneto magnets that trigger ignition timing; a damaged flywheel can cause hard starting or no-start conditions, making accurate replacement critical.
The flywheel is bolted to the engine crankshaft and serves as the primary energy storage component in the engine's rotating assembly. It smooths out the power pulses from each combustion cycle, keeping the engine running evenly under load — essential for consistent plate compaction force and steady pump output. On these models, the flywheel also houses the ignition magnets that work with the coil to fire the spark plug; if the flywheel is cracked, chipped, or the magnets are damaged, the engine will lose spark timing and may not start at all.
