The Wacker Neuson Stud is a genuine OEM fastener designed for the PT3V, PT3A, PTK3, and PT3B series 75mm/3in centrifugal trash pumps. As a direct OEM replacement, this stud is manufactured to the same specifications as the original hardware, ensuring correct thread engagement and clamping load across all compatible PT3 pump configurations. Whether you're servicing a PT3A, PT3B, PT3V, or a PTK3 pump kit, this is the factory-authorized part for the job.
Key Features
- Genuine OEM Thread Integrity — Manufactured to exact thread form and material grade specifications, so fastener engagement matches original assembly tolerances on PT3 series pumps.
- Drop-In Hardware Replacement — Installs directly into the original mounting position with no chasing, re-tapping, or thread modification needed.
- Broad PT3 Series Coverage — Confirmed fit across PT3V, PT3A, PTK3, and PT3B 75mm/3in centrifugal trash pump models.
- Maintains Pump Assembly Integrity — A worn, stripped, or broken stud can compromise housing sealing and component clamping; replacing with the correct OEM stud restores proper torque retention and pump assembly stability.
- Factory-Authorized Part — Sourced directly from Wacker Neuson, this stud carries the same part number — 5000077801 — used by authorized service dealers worldwide.
A stud is a headless threaded fastener used to secure pump housings, covers, or structural components together. Unlike a bolt, a stud remains fixed in one mating surface while a nut is torqued onto the exposed end, allowing for more consistent clamping force and easier component removal during service. When a stud is damaged, corroded, or sheared, it can prevent proper sealing of pump assemblies — leading to leaks, misalignment, or the inability to reassemble the unit correctly. Replacing a failed stud with the correct OEM part restores the pump to its designed clamping specification.
