The Wacker Neuson is a genuine OEM Carriage Bolt designed for the PDT3, PDT3A, PDI3, and PDI3A series 75mm/3in diaphragm trash pumps. Sourced directly from Wacker Neuson, this fastener meets the exact specifications used in original production, ensuring a correct, secure fit every time. It is compatible across multiple pump configurations within the PDT3 and PDI3 families, including both standard and inline variants. Confirming part number against your pump's serial number before ordering is always recommended.
Key Features
- Genuine OEM Fastener Grade: — Manufactured to the same torque and tensile specifications as the original hardware, maintaining the structural integrity of the pump assembly.
- Direct-Fit Replacement: — Engineered to match the original thread pitch, diameter, and head profile, so it seats and tightens exactly as the factory hardware does.
- Broad PDT3 and PDI3 Family Coverage: — Compatible with PDT3, PDT3A, PDI3, and PDI3A 75mm/3in diaphragm trash pumps across multiple production configurations.
- Maintains Pump Integrity Under Load: — A correctly torqued carriage bolt prevents casing separation and fluid leaks, keeping pump components firmly seated during demanding pumping operations.
- Secure Fastening Without Rotation: — The carriage bolt's square shoulder locks it against rotation as the nut is tightened, making installation straightforward even in tight pump housing areas.
A carriage bolt is a structural fastener used to clamp and secure pump housing panels, covers, or frame components together. Its domed head and square shoulder are designed to pull flush into the mounting surface, resisting spin-out during tightening without requiring a wrench on the bolt head. When a carriage bolt is worn, corroded, or missing, the clamped joint it holds can loosen under vibration, leading to misalignment, leaks, or premature wear of surrounding components. Replacing it with the correct OEM part ensures the joint returns to its original clamping specification.
