The Wacker Neuson U-Bolt is a genuine OEM component designed for PT3A, PT4A, PT3A(I), and PT4A(I) series self-priming centrifugal trash pumps. Sourced directly from Wacker Neuson, this U-Bolt meets the exact specifications of the original hardware used on the production line. It is a direct replacement for worn or damaged fastening hardware across the PT3A and PT4A pump families, including both standard and indirect-priming configurations. Whether you are completing a scheduled service or repairing a pump in the field, part number ensures correct fitment without guesswork.
Key Features
- Genuine OEM Hardware Integrity — Manufactured to Wacker Neuson's original dimensional tolerances, ensuring the correct thread pitch, bend radius, and material grade for secure clamping performance.
- Drop-In Replacement — Matches the original mounting configuration on PT3A and PT4A pumps, aligning with existing mounting points for a straightforward installation.
- Broad PT-Series Compatibility — Fits PT3A, PT4A, PT3A(I), and PT4A(I) trash pump models, covering both standard and indirect-priming variants in the 3- and 4-inch discharge families.
- Structural Fastening Reliability — A properly torqued U-Bolt keeps critical pump components securely anchored during high-vibration operation; a loose or damaged one can allow movement that stresses adjacent fittings and connections.
- Verified Part Number — Order with confidence using Wacker Neuson part number 5100050894, cross-referenced across all listed PT3A and PT4A model configurations.
A U-Bolt is a curved fastener shaped like the letter U, threaded on both ends, used to clamp and secure components to a frame or mounting surface. On Wacker Neuson trash pumps, it anchors pump assemblies or associated hardware in place, preventing movement and maintaining alignment during operation. When a U-Bolt becomes bent, corroded, or stripped, it can no longer maintain the clamping force needed to keep components stable, which may lead to vibration-related wear or loosening of adjacent parts over time.
