The Multiquip EM514633 Exhaust Reduction Tube is a genuine OEM component designed for hydraulic-driven concrete pump models LS400, LS500, LS600, LS40TD, LS50TD, and LS60TD. As a factory-sourced replacement, this part matches the original specification exactly, ensuring proper exhaust routing and sealing without adaptation or guesswork. DHS Equipment supplies this part directly as an authorized Multiquip OEM replacement, so you can be confident you are receiving the correct component for your machine. Verify your model code against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Exhaust Specification: — Sourced directly from Multiquip, this tube meets the original exhaust diameter and material spec for LS-series concrete pumps — no dimensional compromise in the exhaust path.
- Drop-In Replacement: — Engineered to match the original mounting points and exhaust outlet dimensions, allowing straightforward installation on the machines it was built for.
- Broad LS-Series Fitment: — Compatible with LS400, LS500, LS600, LS40TD, LS50TD, and LS60TD hydraulic-driven concrete pump models, covering a wide range of Mayco pump configurations.
- Maintains Proper Exhaust Flow: — A correctly fitted exhaust reduction tube channels combustion gases safely away from the engine, protecting operator safety and preventing heat buildup around the pump assembly.
- Exhaust Integrity Matters: — A cracked, corroded, or poorly fitted reduction tube can direct hot exhaust gases toward surrounding components or operators. Replacing with an OEM part restores the designed exhaust pathway.
The exhaust reduction tube serves as a transition fitting within the engine exhaust system, stepping down the exhaust outlet diameter to match the downstream exhaust piping or muffler connection. On hydraulic-driven concrete pumps like the LS-series, maintaining a sealed and correctly sized exhaust path is essential for safe engine operation and compliance with emissions routing design. When this tube corrodes, cracks, or develops leaks, exhaust gases can escape at unintended points, creating heat hazards and reducing engine backpressure management — making timely replacement with the correct OEM part critical.
