The Wacker Neuson Washer is a genuine OEM component designed for a range of Wacker Neuson equipment including CT36BDT and CT48BDT walk-behind concrete trowels, PT2B and PT3B centrifugal trash pumps, PD3B diaphragm pumps, and B 3000 and B 5000 gasoline power units for internal vibrators. As a factory-sourced part, it is manufactured to the exact material and dimensional specification of the original, ensuring a direct, correct fit wherever this washer is used in the assembly. Sourcing the correct OEM washer matters — an undersized, oversized, or wrong-grade substitute can cause uneven load distribution, fastener loosening, or premature wear on surrounding components. Keep a verified replacement on hand to restore your equipment to full operating condition without guesswork.
Key Features
- OEM Material and Dimensional Spec — Manufactured to the exact thickness, inner diameter, and hardness grade of the original, ensuring proper load distribution across the fastener joint.
- Direct Drop-In Replacement — Matches the original seating surface and bore, so it installs straight into the existing fastener position without rework or shimming.
- Broad Fitment Across Multiple Machine Families — Confirmed fit for CT36BDT and CT48BDT walk-behind trowels, PT2B and PT3B trash pumps, PD3B diaphragm pumps, and B 3000 / B 5000 gasoline power units.
- Protects Mating Surfaces — Correctly rated washers prevent fastener heads from pulling through or embedding into softer housing material, preserving the integrity of surrounding components.
- Genuine Wacker Neuson OEM Part — Supplied through the authorized Wacker Neuson parts network under part number 5000039296, with full traceability back to the original equipment specification.
A washer distributes the clamping load of a bolt or nut across a wider surface area, preventing damage to the material being fastened and maintaining consistent joint tension over time. In equipment that is subject to vibration — such as concrete trowels, trash pumps, and engine-driven power units — washers play a critical role in keeping fastened assemblies tight and secure through continuous mechanical stress. When a washer is missing, deformed, or the wrong specification, fasteners can work loose, mating surfaces can become damaged, and the structural integrity of the assembly can be compromised, leading to more extensive and costly repairs.
