The Wacker Neuson 5200019990 Bolt is a genuine OEM fastener designed for the APT4T and APT4S pump series, including surge brake, electric brake, and cold weather configurations. As a genuine OEM component, it is manufactured to the exact specifications required by Wacker Neuson, ensuring a correct, consistent fit every time. This bolt is confirmed compatible across the full APT4T and APT4S pump lineup, covering both standard and cold weather variants. Sourcing the correct bolt by part number 5200019990 is the simplest way to ensure structural integrity at the point of installation.
Key Features
- Genuine OEM Specification: — Manufactured to exact Wacker Neuson thread pitch, grade, and dimensional tolerances — not an approximate match.
- Drop-In Installation: — Threads and head dimensions align directly with existing hardware points on APT4T and APT4S pump assemblies, requiring no modification to mating components.
- Broad APT Series Coverage: — Fits APT4T Pump with Surge Brake, APT4T Pump with Electric Brake, APT4S Pump with Skid, and all corresponding Cold Weather variants.
- Structural Integrity Under Load: — A correctly torqued, properly spec'd bolt keeps pump assemblies and mounting points secure during operation — a worn or incorrect fastener risks loosening under vibration and pump pressure cycles.
- Verified by Part Number: — Cross-reference part number 5200019990 against your machine's serial number and configuration before ordering to confirm fitment for your specific unit.
A bolt in a pump assembly serves as the primary fastener holding critical components — such as mounting brackets, covers, or structural panels — in proper alignment under operational loads. On self-priming trash pumps like the APT4T and APT4S, pump housings and attached hardware are subjected to vibration, pressure fluctuation, and mechanical stress during every run cycle. A bolt that is worn, stripped, or replaced with an incorrect grade or thread pitch can compromise clamping force, leading to misalignment, leaks, or component separation. Using the correct OEM-specified fastener maintains the structural integrity the pump was engineered around.
