Wacker Neuson 5000151409 Adjusting Washer

The Wacker Neuson is a genuine OEM Adjusting Washer designed for a broad range of Wacker Neuson diesel-powered compaction equipment, self-priming trash pumps, and hydronic surface heating systems. This is a direct factory replacement sourced through Wacker Neuson's authorized parts program, ensuring the correct material grade, thickness, and dimensional tolerancing for your application. Compatible machines include the DPU 2440H through DPU 6275H reversible vibratory plate series, DPS 1850H and DPS 2050H single-direction vibratory plates, PT2H and PT3H centrifugal trash pumps, the HSH350 Hydronic Surface Heater, and the DS70 vibratory rammer. With fitment spanning this many machine families, always verify your model and machine number before ordering.

Key Features

• Genuine OEM Material and Dimensional Accuracy — Manufactured to Wacker Neuson's exact thickness and hardness specification, so the washer delivers correct load distribution and does not compress, deform, or allow unwanted shaft play over time.
• Drop-In Replacement for the Correct Stack-Up — The 5000151409 seats directly into the existing assembly position without shimming or modification, restoring the designed axial clearance in one step.
• Wide Cross-Family Fitment — Covers DPU and DPS reversible and single-direction vibratory plate compactors, PT2H and PT3H trash pumps, the HSH350 hydronic surface heater, the DS70 rammer, and the E1100 ground heater — all confirmed under a single OEM part number.
• Maintains Proper Bearing and Shaft Alignment — A worn or missing adjusting washer allows excess axial movement, which accelerates bearing wear, increases vibration, and can lead to premature failure of adjacent rotating components.
• Authorized OEM Supply Chain — Sourced through Wacker Neuson's official parts network, so the part number, revision level, and material spec match what was originally installed at the factory.

An adjusting washer is a precision-thickness spacer used to set and maintain the correct axial clearance — or "end play" — between rotating components such as shafts, bearings, and housings. By occupying a defined amount of space within the assembly stack, it prevents the shaft from moving too far in either direction during operation, which keeps bearing loads within their designed range. When an adjusting washer wears thin, cracks, or goes missing, the resulting excess movement puts uneven stress on bearings and seals, causing accelerated wear, increased heat, and eventual component failure across multiple machine types — from compactor exciter units to pump impeller shafts.
