The Wacker Neuson 5100044507 Bolt is a genuine OEM fastener designed for PT3A, PT4A, PT3A(I), and PT4A(I) series self-priming centrifugal trash pumps. As a factory-sourced component, it is manufactured to the exact dimensions and material grade specified for these pumps, ensuring a correct and secure fit every time. This bolt is confirmed compatible across multiple PT-series configurations, making it a straightforward replacement when servicing your pump.
Key Features
- Genuine OEM Material Grade — Manufactured to Wacker Neuson's specified tensile and thread standards for fasteners used in trash pump assemblies, so clamping force and thread engagement meet original design requirements.
- Direct Bolt-In Replacement — Matches the original thread pitch, diameter, and length, seating into existing threaded bores without any rework or modification to mating components.
- Broad PT-Series Compatibility — Confirmed fit across PT3A, PT4A, PT3A(I), and PT4A(I) pump models, covering both standard and industrial configurations in the 3- and 4-inch discharge families.
- Structural Integrity Where It Counts — A correctly torqued OEM bolt maintains housing alignment and sealing pressure; a worn, stripped, or incorrect fastener can allow casing separation or fluid leaks under pump operating loads.
- Fluid System Safety — On a self-priming trash pump handling liquids under pressure, a properly rated fastener helps prevent unintended casing separation, protecting operators and the work site from unexpected fluid discharge.
Bolts in a trash pump assembly do more than hold the housing together — they maintain the compression and alignment needed for the pump's volute, impeller, and wear plate to function as a sealed system. When a bolt stretches, strips, or fails, internal components can shift, casing joints can weep, and prime can be lost. Replacing a damaged or missing fastener with the correct OEM-specification bolt restores the clamping integrity the pump depends on to move water and solids reliably under continuous load.
