The Wacker Neuson 5200020043 Bolt is a genuine OEM fastener designed for APT4T and APT4S series pumps. As a direct OEM replacement, this bolt is manufactured to the exact specifications required by Wacker Neuson, ensuring correct thread pitch, grade, and dimensional fit for the application. Compatible across multiple APT4T and APT4S configurations — including surge brake, electric brake, and cold weather variants — this single part number covers a broad range of units in the APT pump lineup. Whether you're servicing a standard APT4S Pump w/Skid or an APT4T Pump in a Cold Weather configuration, the 5200020043 is the correct OEM choice.
Key Features
- OEM-Grade Fastener Integrity — Manufactured to Wacker Neuson's exact thread specification and hardness grade, so torque values and clamping force remain consistent with the original assembly.
- Drop-In Replacement — Threads directly into the existing hardware points on APT4T and APT4S pump assemblies with no modification to mating components.
- Broad APT Series Compatibility — Fits APT4T Pump configurations with surge brake, electric brake, and cold weather options, as well as APT4S Pump w/Skid models in both standard and cold weather variants.
- Structural Confidence Under Load — A correctly spec'd bolt maintains proper joint tension throughout pump operation; an incorrect or worn fastener risks joint loosening, misalignment, or component separation under vibration.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, carrying the same part number used by authorized service centers for APT pump maintenance and repair.
A bolt in a pump assembly does more than hold components together — it maintains the clamping load that keeps mating surfaces sealed and aligned under continuous operating stress. In pump applications where vibration is constant, an improperly sized or incorrect-grade fastener can back out, stretch, or fail, leading to component movement, fluid leaks, or more serious mechanical damage. Using the correct OEM fastener like the Wacker Neuson 5200020043 ensures the joint performs exactly as engineered throughout the service life of the pump.
