Wacker Neuson 5000402178 Drain Oil Hose Assembly

The Wacker Neuson Drain Oil Hose Assembly is a genuine OEM drain oil hose assembly designed for a wide range of Wacker Neuson vibratory plate compactors, including the WPU1550A, WP1235A, WP1540A, WP1550A, WP2050A, WPP1540A, WPP1550A, and their Aw and US variants. Sourced directly from Wacker Neuson, this assembly carries the same part specifications as the original component fitted at the factory, so you're installing exactly what belongs in your machine. Whether you're servicing a single-direction plate or a reversible plate model, part number covers an extensive lineup of WP and WPU series compactors. Keep your oil change routine clean and straightforward — this assembly ensures fluid is routed and drained correctly every time.

Key Features

• OEM Hose Integrity — Manufactured to the same material and dimensional specifications as the original, ensuring the hose withstands the heat cycles and fluid exposure typical of vibratory plate compactor operation.
• Direct-Fit Replacement — Connects to the existing drain port using the original routing and attachment points, so there's no cutting, splicing, or adapting required during installation.
• Broad Vibratory Plate Compatibility — Fits WPU1550A, WP1235A, WP1540A, WP1550A, WP2050A, WPP1540A, WPP1550A series compactors, including Aw, L, LL, and US configurations.
• Clean Oil Changes Every Time — A properly functioning drain hose assembly directs used oil away from the machine cleanly, protecting surrounding components and keeping service intervals quick and mess-free.
• Leak Prevention — A worn or cracked drain hose can allow oil to escape onto the exciter housing or surrounding components, leading to contamination and potential exciter damage. Replacing it promptly with a genuine OEM part eliminates that risk.

The drain oil hose assembly provides a dedicated fluid path for removing used oil from the exciter housing during routine oil changes on vibratory plate compactors. Without a properly sealed and routed hose, oil drainage becomes imprecise — increasing the risk of spills, incomplete drains, or contamination of external surfaces. A damaged or degraded hose can also allow oil to seep continuously, depleting lubricant levels in the exciter and accelerating internal wear if left unaddressed.
