The Wacker Neuson Flat Washer is a genuine OEM component designed for the PT2A, PT3A, and PT4A series self-priming centrifugal trash pumps, including indirect-drive variants. As a direct Wacker Neuson OEM part, the is manufactured to the exact material grade, thickness, and dimensional tolerances specified for these pumps — ensuring proper load distribution and secure fastener seating throughout the assembly. This washer fits across the full PT2A, PT3A, PT4A, PT2A(I), PT3A(I), and PT4A(I) model range, making it a versatile stock item for crews running multiple pump sizes on the same jobsite.
Key Features
- OEM-Grade Material Specification — Manufactured to Wacker Neuson's exact material and dimensional standards, delivering the correct hardness and surface finish needed for consistent load distribution in pump assemblies.
- Drop-In Replacement — Matches the original mounting hole diameter and outer diameter precisely, seating correctly against fastener heads and mating surfaces without adjustment or rework.
- Broad PT-Series Compatibility — Confirmed fitment across PT2A, PT3A, PT4A, PT2A(I), PT3A(I), and PT4A(I) trash pump models, covering both standard and indirect-drive configurations.
- Protects Fastener Integrity — Proper washer seating prevents fastener pull-through and surface deformation under vibration and load — critical in high-cycle pump environments where fastener loosening accelerates wear.
- Genuine OEM Part — Sourced directly from Wacker Neuson, carrying the correct part number 5100050898 for confident ordering and parts record accuracy.
A flat washer distributes the clamping load of a bolt or nut across a broader surface area, preventing damage to the material beneath and keeping fasteners secure under sustained vibration and operational stress. In trash pumps like the PT2A, PT3A, and PT4A series, components are exposed to continuous engine vibration and hydraulic forces that can cause improperly supported fasteners to loosen or bore into softer surfaces over time. A worn, undersized, or missing flat washer compromises joint integrity, which can lead to leaks, misalignment, or accelerated wear at critical connection points.
