The Wacker Neuson 5200020091 Bolt is a genuine OEM component designed for APT4T and APT4S series pumps. As a direct factory replacement, this bolt delivers the correct dimensions, thread pitch, and material grade required for proper assembly and long-term hold in demanding pump applications. It is compatible across multiple APT4T and APT4S configurations, including Surge Brake, Electric Brake, and Cold Weather variants, as well as APT4S Pump with Skid models. Sourcing the correct OEM bolt ensures the fastened joint maintains its integrity under the vibration and load cycles these pump units encounter in the field.
Key Features
- Genuine OEM Thread and Grade Accuracy — Manufactured to the exact thread specification and material grade called out in the Wacker Neuson assembly, eliminating the risk of thread mismatch or fastener fatigue common with generic substitutes.
- Drop-In Assembly Fit — Engineered to install directly into the existing mounting point without reworking threads or modifying the surrounding hardware.
- Broad APT4T and APT4S Compatibility — A single part number covers Surge Brake, Electric Brake, Cold Weather, and Pump with Skid variants across both the APT4T and APT4S model families.
- Structural Integrity Under Pump Operation — A correctly torqued, properly graded bolt keeps critical pump components secured during operation; a fatigued or mismatched bolt can lead to joint movement, misalignment, and accelerated component wear.
A bolt in a pump assembly serves as the primary fastener holding structural or functional components in their correct position. In pump applications like the APT4T and APT4S, fasteners must withstand continuous vibration and fluid-transfer loads without loosening or failing. When a bolt wears, strips, or is replaced with an incorrect grade or thread pitch, it can compromise the alignment and security of the components it retains, leading to leaks, misalignment, or component separation during operation.
