The Multiquip 200403 Exhaust Manifold LS300G is a genuine OEM exhaust manifold designed for the LS300G hydraulic-driven concrete pump. As a direct Multiquip OEM component, it is manufactured to the exact specifications required by the LS300G, ensuring a correct fit without guesswork or modification. DHS Equipment stocks this part to keep your concrete pump running at full capacity when you need it most. Verify your model code against LS300G to confirm compatibility before ordering.
Key Features
- Genuine OEM Construction — Cast and finished to the same material and dimensional standards as the original exhaust manifold on the LS300G, preserving proper exhaust flow and heat tolerance.
- Direct-Mount Replacement — Matches the original bolt pattern and port configuration of the LS300G engine bay, allowing straightforward removal and reinstallation.
- LS300G Concrete Pump Fitment — Sourced specifically for the LS300G hydraulic-driven concrete pump; confirm your model code before ordering.
- Sustained Engine Performance — A correctly sealed exhaust manifold maintains proper back pressure and prevents exhaust gas leaks that can cause engine overheating, power loss, or sensor interference on the LS300G.
- Fuel System and Emissions Integrity — Exhaust leaks at the manifold can introduce combustion gases into the engine bay and affect fuel mixture readings; replacing a cracked or warped manifold restores safe, compliant operation.
The exhaust manifold collects spent combustion gases from the engine's cylinder ports and routes them into the exhaust system. It must withstand extreme heat cycling while maintaining a gas-tight seal against each cylinder head port — a failure at any joint allows hot exhaust gases to escape into the engine compartment, which accelerates wear on surrounding components and reduces engine efficiency. On a hydraulic-driven concrete pump like the LS300G, where consistent engine output directly drives pump performance, a warped, cracked, or leaking manifold can cause noticeable drops in hydraulic pressure and output volume.
