The Wacker Neuson 5000400304 Water Manifold Complete is a genuine OEM component designed for WP1540 and WP1550 series single-direction vibratory plate compactors. As a direct OEM replacement, this assembly is manufactured to the same specifications as the original part, ensuring a correct, trouble-free installation on your machine. It fits a wide range of WP1540 and WP1550 variants, including standard, asphalt, and wheel-kit-equipped configurations. Always verify your model number before ordering to confirm compatibility.
Key Features
- Genuine OEM Construction — Manufactured to original design specs, meaning correct port sizing, thread pitch, and flow characteristics are preserved — no guesswork on water distribution performance.
- Complete Assembly — Supplied as a complete manifold unit, so all internal passages and fittings are pre-assembled and ready to install as a single, drop-in replacement.
- Broad WP Series Compatibility — Fits a wide range of WP1540 and WP1550 model variants, including A, AW, V, VW, R, RW, and W configurations, as well as wheel-kit-equipped machines.
- Consistent Water Distribution — A properly functioning water manifold ensures even water flow across the plate surface, which is essential for asphalt compaction work where sticking and surface damage must be prevented.
- Sourced Direct from Wacker Neuson — Part number 5000400304 is an authorized Wacker Neuson OEM part, backed by the manufacturer's parts program for traceability and confidence.
The water manifold on a vibratory plate compactor distributes water evenly across the compaction plate surface during asphalt work, preventing hot asphalt from sticking to the baseplate and protecting both the machine and the mat finish. When the manifold becomes cracked, blocked, or begins leaking, water distribution becomes uneven or stops entirely, causing asphalt to adhere to the plate and potentially damaging the surface being compacted. Replacing a failed or worn manifold restores proper water coverage and allows the machine to continue asphalt compaction work cleanly and efficiently.
