The Wacker Neuson Washer is a genuine OEM replacement built for the PT3A, PT4A, PT3A(I), and PT4A(I) series trash pumps. As a factory-sourced component, the meets the same dimensional and material standards as the original part it replaces, ensuring a correct, trouble-free installation. This washer is verified against multiple PT-series configurations, making it a straightforward drop-in replacement for scheduled maintenance or repair work.
Key Features
- OEM Material and Dimensional Accuracy — Manufactured to the exact thickness, bore, and hardness spec of the original washer, so load distribution and clamping force are maintained as designed.
- Direct Drop-In Replacement — Seats and torques identically to the factory-installed washer, requiring no filing, shimming, or adjustment during reassembly.
- Broad PT-Series Coverage — Confirmed fitment across PT3A, PT4A, PT3A(I), and PT4A(I) pump models, covering both standard and metric-compatible configurations in that family.
- Preserves Proper Fastener Clamping — A correctly spec'd washer spreads fastener load evenly across the mating surface; an undersized or worn washer can allow fasteners to loosen under vibration, leading to leaks or component damage.
- Genuine Wacker Neuson Part — Sourced directly through the Wacker Neuson OEM supply chain and identified by part number 5100044497 for confident, error-free ordering.
A washer serves as a load-distributing interface between a fastener — such as a bolt or nut — and the surface it clamps against. By spreading the clamping force over a wider area, it prevents the fastener from pulling through or damaging softer materials and helps maintain consistent tension over time, even under the vibration typical of pump operation. When a washer is missing, deformed, or incorrectly sized, fastener tension becomes uneven, which can allow joints to work loose, cause surface damage to housings or covers, and ultimately lead to leaks or component misalignment.
