The Wacker Neuson is a genuine OEM Cheese Head Screw designed for the PTS4V, PT3A, PT3B, PT3V, PT3Y, PTK3, and PTK4 centrifugal trash pump series. As a factory-sourced component, this screw is manufactured to the exact dimensions and material grade specified by Wacker Neuson, ensuring a direct, correct-fit installation with no guesswork. It serves across multiple pump configurations — including the 75mm/3-inch and 100mm/4-inch variants — making it a versatile stocking item for fleets running mixed pump lineups. Keep part number on hand to avoid delays when routine maintenance or field repairs call for hardware replacement.
Key Features
- Genuine OEM Hardware Grade — Manufactured to Wacker Neuson's exact material and thread specification, so torque values and clamping force match what the pump assembly was engineered around.
- Direct Drop-In Installation — The cheese head profile and thread form align with the original mounting points on the pump housing, requiring no reworking of existing hardware positions.
- Broad Pump Family Coverage — Fits PTS4V, PT3A, PT3B, PT3V, PT3Y, PTK3, and PTK4 series centrifugal trash pumps in both standard and pump-kit configurations.
- Structural Integrity at the Source — Correct fastener spec prevents loosening under pump vibration, which can lead to housing misalignment, seal failure, or fluid ingress if left unchecked.
- Verified Part Number Traceability — Sourced directly through the Wacker Neuson OEM supply chain, so 5000051562 matches the part listed in your machine's service manual without cross-referencing substitutes.
A cheese head screw is a machine fastener identified by its cylindrical head with a flat top and straight sides — designed to sit flush or semi-recessed within a counterbored or clearance hole in a housing assembly. On centrifugal trash pumps like the PTS4V and PT3 series, fasteners like this one secure critical pump components including volute covers, bearing housings, and mounting plates. When a fastener of this type is missing, stripped, or substituted with an incorrect thread or head profile, it can cause joint separation or vibration-induced loosening during pump operation, potentially leading to water ingress, seal damage, or catastrophic housing failure in demanding jobsite conditions.
