The Wacker Neuson 5200019841 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 direct-from-manufacturer component, this bolt is produced to the same specifications as the original hardware installed at the factory, ensuring correct fit across all covered variants. Confirmed fitment includes the APT4T Pump with Surge Brake, APT4T Pump with Electric Brake, APT4S Pump with Skid, and their respective Cold Weather counterparts. When replacing worn or damaged hardware, using the correct OEM bolt keeps structural connections secure and prevents assembly issues caused by incorrect thread pitch or dimensional variance.
Key Features
- Genuine OEM Hardware Grade — Manufactured to the exact dimensional and tensile specifications of the original bolt, maintaining correct clamping force for pump assembly joints.
- Drop-In Replacement — Matches original thread pitch, diameter, and head spec for straightforward installation with no modifications to mating components.
- Broad APT Series Fitment — Compatible with APT4T Pump (Surge Brake and Electric Brake) and APT4S Pump with Skid, including all Cold Weather variants of each.
- Structural Integrity — A correctly torqued, properly sized bolt keeps pump housings, brackets, and attached components securely fastened under operational vibration and load.
- Prevents Costly Secondary Damage — A stripped, undersized, or incorrect bolt can allow movement in critical joints, leading to accelerated wear on surrounding components and unplanned repairs.
A bolt in a pump assembly serves as the primary fastener holding structural and functional components together — housing sections, mounting brackets, and connected hardware all depend on correctly specified fasteners to maintain alignment and resist vibration-induced loosening. When a bolt fails, stretches, or is replaced with an incorrect substitute, joint integrity is compromised, which can allow movement between mating surfaces and lead to leaks, misalignment, or component damage. Using the correct OEM bolt ensures the connection performs as originally engineered throughout the service life of the pump.
