The Wacker Neuson Bolt is a genuine OEM bolt designed for the PD series diaphragm pump lineup, including PDT2A, PDT2, PDI2A(I), PDT3A, PDT3, PDI3A, and PDI3A(I) models. As a direct OEM replacement, this bolt is manufactured to the same specification as the part originally installed at the factory, ensuring a correct fit without guesswork. It is a verified match across multiple PD series machine numbers, covering both 2-inch and 3-inch diaphragm pump configurations. Keep a spare on hand to minimize unplanned service interruptions during pump maintenance or repair.
Key Features
- Genuine OEM Specification — Manufactured to Wacker Neuson's exact dimensional and material requirements, so thread pitch, shank length, and head geometry match the original hardware precisely.
- Direct-Fit Replacement — Installs into the same mounting position as the factory bolt with no modification to mating components or fastener seats.
- Broad PD Series Coverage — Compatible with PDT2A, PDT2, PDI2A(I), PDT3A, PDT3, PDI3A, and PDI3A(I) diaphragm pumps across multiple machine numbers.
- Structural Integrity Under Pump Loads — A correctly torqued replacement bolt maintains proper clamping force on pump housings and covers, preventing leaks and loosening during continuous operation.
- Verified Part Number — Sourced directly from Wacker Neuson under part number 5000179862, eliminating the risk of ordering a mismatched fastener for your pump model.
Bolts in diaphragm pump assemblies serve as the primary fasteners that clamp housing sections, valve covers, and diaphragm retainer plates together under consistent clamping force. On a working pump, these fasteners must maintain their torque rating through repeated pressure cycles, vibration, and exposure to fluids — if a bolt stretches, strips, or fails to seat correctly, the result is housing leaks, reduced pumping performance, or premature diaphragm wear. Replacing a damaged or worn fastener with a correctly specified OEM bolt restores the assembly to its designed clamping load and keeps the pump operating as intended.
