The Multiquip 03919800 is a genuine OEM Exhaust Manifold 2G40 RW1404 designed for RAMMAX walk-behind roller models including the RW1404, RW1404MR, and RW1504HF. As a direct Multiquip OEM component, 03919800 meets the same design and material standards as the original part fitted at the factory. This manifold is compatible with the RW1404MR from S/N 326075 and up, and with the RW1504HF up to S/N — confirm your serial number before ordering to ensure the correct application. Sourcing genuine OEM ensures a straight-swap installation with no guesswork on fit or function.
Key Features
- Genuine OEM Construction — Cast to the original material and dimensional specification for the 2G40 engine exhaust application, maintaining correct port alignment and sealing surface integrity.
- Direct-Swap Installation — Mounts to the existing exhaust port and hardware positions on compatible RAMMAX roller engines without alteration to surrounding components.
- Confirmed Roller Fitment — Verified for RW1404, RW1404MR (S/N 326075 and up), and RW1504HF (up to S/N 1534188) RAMMAX walk-behind rollers.
- Engine Exhaust Flow Integrity — A properly sealed exhaust manifold keeps combustion gases routed correctly, protecting engine efficiency and preventing heat and pressure losses that can degrade output over time.
- Exhaust System Safety — A cracked or warped manifold allows hot exhaust gases to escape toward the operator and surrounding components; replacing a failed unit promptly addresses a genuine safety concern on powered compaction equipment.
The exhaust manifold collects spent combustion gases from the engine's cylinder head and channels them out through the exhaust system. On a walk-behind roller like the RW1404 series, a sound manifold is essential for maintaining correct engine back-pressure, fuel efficiency, and overall power output. When the manifold cracks, warps, or develops a blown gasket surface, exhaust gases leak at the joint, causing increased noise, loss of engine performance, and potential heat damage to nearby fuel and electrical lines.
