The Wacker Neuson 5200020109 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 factory-sourced component, it is manufactured to the exact specifications required by Wacker Neuson, ensuring a correct, secure fit within the assembly. This bolt is compatible across multiple APT4T and APT4S variants, making it the right choice for operators maintaining any configuration within these pump families. Confirm your machine's model number before ordering to ensure this is the correct fastener for your application.
Key Features
- Genuine OEM Fastener Grade — Sourced directly from Wacker Neuson, this bolt meets the exact thread pitch, shank diameter, and tensile strength specified for the APT4T and APT4S pump assemblies.
- Drop-In Replacement — Engineered to the original dimensions, this bolt installs directly into the existing fastener location without modification to surrounding hardware or mating components.
- Broad APT4 Series Coverage — Fits the APT4T Pump with Surge Brake, APT4T Pump with Electric Brake, APT4S Pump with Skid, and Cold Weather variants of both series.
- Structural Integrity Under Load — A properly torqued, correctly specified bolt keeps pump components firmly seated during operation; an incorrect or worn fastener can allow movement that leads to misalignment or component damage.
- Critical Fastener for Brake and Pump Systems — Used across Surge Brake and Electric Brake configurations, correct bolt specification is essential for maintaining the mechanical integrity of brake-related assemblies on trailer-mounted pump units.
A bolt in a pump assembly serves as the primary mechanical fastener holding structural or functional components together under operational stress. In the APT4T and APT4S pump systems — which are trailer-mounted units designed for self-priming water transfer — fasteners must maintain clamping force against vibration, hydraulic load, and frequent trailer movement. When a bolt stretches, strips, or is replaced with an incorrect substitute, it can compromise the alignment and security of connected components, potentially leading to leaks, mechanical failure, or brake system issues in trailer-mounted configurations. Using the correct OEM-specified fastener ensures the assembly remains tight and functions as designed.
