The Wacker Neuson 5200021818 Bolt is a genuine OEM fastener designed for the APT4T and APT4S series self-priming centrifugal trash pumps. As a factory-sourced component, it meets the exact specifications set during original manufacture, ensuring proper clamping force, thread engagement, and material grade for the application. This bolt is confirmed to fit across multiple APT4T and APT4S configurations, including surge brake, electric brake, and cold weather variants. Whether you are servicing a standard unit or a cold weather-equipped pump, part number 5200021818 is the correct replacement.
Key Features
- Genuine OEM Material Grade — Sourced directly from Wacker Neuson, this bolt is manufactured to the exact tensile strength and thread specification required for the pump assembly, preventing loosening or fastener failure under sustained vibration and load.
- Direct-Fit Replacement — Threads, head size, and shank dimensions match the original hardware exactly, allowing straightforward installation without reworking mounting points or mating components.
- Broad APT4T and APT4S Compatibility — Fits surge brake, electric brake, and cold weather configurations across both the APT4T and APT4S pump series, making it a versatile service part for mixed fleets.
- Maintains Structural Integrity — A correctly torqued, properly spec'd bolt keeps pump housings, mounts, and covers sealed and aligned. A worn, stripped, or incorrect fastener can allow misalignment, leaks, or component separation during operation.
- Verified OEM Part Number — Cross-referenced against Wacker Neuson parts documentation so you can order with confidence that 5200021818 is the correct fastener for your machine.
A bolt at this location on a trash pump assembly serves as a critical fastener holding structural or cover components securely together during operation. Trash pumps handle demanding pumping cycles and generate consistent vibration, placing ongoing stress on every fastener in the assembly. When a bolt stretches, strips, or is substituted with an incorrect grade, it can compromise housing alignment, allow fluid ingress, or cause component separation — all of which interrupt pumping operations and can lead to more extensive damage if left unaddressed.
