The Wacker Neuson 5200020188 Bolt is a genuine OEM fastener designed for APT4T and APT4S series self-priming pumps. As a direct factory replacement, this bolt is sourced and specified to match the original hardware used during manufacture, ensuring correct torque retention and structural integrity at the installation point. Compatible across multiple APT4T and APT4S configurations — including Surge Brake, Electric Brake, and Cold Weather variants — the 5200020188 is the correct replacement when original hardware is damaged, stripped, or lost during service.
Key Features
- Genuine OEM Hardware Spec: — Manufactured to the exact thread pitch, grade, and dimensional tolerances called out in the Wacker Neuson parts manual, ensuring proper clamping force at the fastened joint.
- Drop-In Replacement: — Matches the original bolt profile, allowing direct installation without chasing threads or sourcing additional hardware.
- Broad APT Series Fitment: — Confirmed compatible with APT4T Pump (Surge Brake and Electric Brake), APT4S Pump with Skid, and Cold Weather variants across both series.
- Structural Integrity at the Joint: — A correctly torqued OEM bolt maintains the designed clamping load; an underspec or worn fastener can allow joint movement, leaks, or component misalignment under pump operating pressure.
A bolt in a pump assembly serves as the primary mechanical fastener holding housings, covers, flanges, or mounting brackets in correct alignment under continuous vibration and fluid pressure. When a bolt is stripped, corroded, or broken, the joint it secures can shift or separate, leading to fluid leaks, premature seal wear, or component damage. Replacing a failed bolt with the correct OEM specification fastener restores the designed clamping load and keeps the pump operating as intended.
