The Multiquip 40084700 ST45 Bushing is a genuine OEM component designed for the ST45 swing tube concrete pump. Sourced directly from Multiquip, this bushing is manufactured to the same standards as the original part installed at the factory, ensuring a correct fit within the ST45 pump assembly. If you're servicing or rebuilding an ST45 concrete pump, this is the exact replacement bushing your machine calls for.
Key Features
- Genuine OEM Material Grade — Machined to the dimensional tolerances required for proper load distribution and wear resistance in a concrete pump bushing application.
- Direct Swap for ST45 Applications — Engineered to seat correctly within the ST45 pump assembly, requiring no machining or custom fitting during installation.
- Confirmed ST45 Fitment — Verified replacement for the Multiquip ST45 swing tube concrete pump series.
- Maintains Pump Stroke Integrity — A worn or failed bushing allows excessive play in the pump mechanism, leading to loss of output pressure and accelerated wear on surrounding components; this OEM replacement restores proper tolerances.
- Authentic Multiquip Part — Part 40084700 is a genuine Multiquip replacement, giving you confidence that the component meets the specifications the ST45 was designed around.
A bushing in a concrete pump serves as a wear interface between moving components, absorbing friction and maintaining proper alignment under the high-stress, high-cycle demands of pumping concrete. When a bushing wears down or fails, it allows unwanted movement between parts, which accelerates damage to the surrounding assembly and can compromise pumping efficiency or cause premature component failure. Replacing a worn bushing promptly with the correct OEM part is one of the most cost-effective ways to protect the broader pump mechanism.
