The Wacker Neuson Washer is a genuine OEM replacement built for the PDT2A, PDT3A, PDI3A, PT3A, PT3A(I), PT4A, and PT4A(I) series pumps. Sourced directly from Wacker Neuson, this washer matches the exact material grade, dimensions, and tolerancing of the original component installed at the factory. Correct fitment is confirmed across multiple pump configurations, making it a straightforward drop-in service part for any of the covered models.
Key Features
- Genuine OEM Material and Dimensional Spec — Manufactured to the same hardness and thickness tolerances as the original, ensuring consistent clamping load and surface distribution across fastened joints.
- Direct Drop-In Replacement — Matches the original bore diameter and outer profile exactly, so it seats correctly without modification during reassembly.
- Broad Pump Series Coverage — Fits PDT2A, PDT3A, PDI3A, PT3A, PT3A(I), PT4A, and PT4A(I) pump models, covering both standard and inlet-primed variants.
- Protects Mating Surfaces — A correctly sized washer distributes fastener load evenly, preventing housing distortion, fretting, and premature wear at the contact point.
- Backed by Wacker Neuson OEM Supply — Carries the Wacker Neuson part number 5100039332, so you can verify compatibility against your service manual or parts diagram before ordering.
A washer acts as a load-spreading interface between a fastener — such as a bolt or nut — and the surface it clamps against. By distributing the clamping force over a larger area, it prevents the fastener from pulling through softer materials, protects machined surfaces from damage, and helps maintain consistent tension across the joint. When a washer is worn, deformed, or missing, the fastener can work loose under vibration, leading to misalignment, leaks, or component failure in the surrounding assembly.
