The Multiquip EM516434 Exhaust Pipe Assembly is a genuine OEM component designed for LS400, LS500, LS40TD, and LS50TD hydraulic-driven concrete pumps. As a direct OEM replacement, EM516434 is manufactured to the same specifications as the original part, ensuring a proper fit within the exhaust system of your Mayco concrete pump. This assembly is confirmed compatible with the LS400, LS500, LS40TD, and LS50TD model lines, giving you confidence that you are ordering the right part the first time.
Key Features
- Genuine OEM Construction — Produced to original Multiquip tolerances and material grades, so the assembly seats, seals, and routes exhaust gases exactly as intended for concrete pump applications.
- Direct Drop-In Replacement — Engineered to match the original mounting points and pipe routing on LS-series concrete pumps, allowing straightforward installation without fabrication or adaptation.
- Broad LS-Series Compatibility — Fits LS400, LS500, LS40TD, and LS50TD Mayco hydraulic-driven concrete pumps, covering both standard and turbo diesel variants in the lineup.
- Sustained Engine Performance — A properly functioning exhaust assembly maintains correct backpressure and vents combustion gases efficiently, supporting consistent engine output and preventing heat buildup around the power unit.
- Exhaust Integrity and Operator Safety — A cracked or failed exhaust assembly can allow hot gases to escape near the engine and operator area; replacing a worn unit restores proper exhaust containment and safe operation on the pour site.
The exhaust pipe assembly routes combustion gases away from the engine and out of the machine safely and efficiently. On concrete pump equipment like the LS-series, maintaining a fully intact exhaust path is critical — a damaged or corroded assembly can cause exhaust leaks that reduce engine efficiency, accelerate heat-related wear on surrounding components, and create hazardous conditions for the operator. Replacing a worn or broken exhaust pipe assembly restores proper gas flow and keeps the power unit running at its intended operating temperature.
