Multiquip 1569491490 Exhaust Manifold Stud

The Multiquip 1569491490 Exhaust Manifold Stud is a genuine OEM component designed for DLW300ES, DLW300ESA, and DLW300ESA1 series diesel light welder/generators. As a direct OEM replacement, this stud is manufactured to the same specifications as the original hardware, ensuring a secure, leak-free connection between the exhaust manifold and engine block. Sourced directly through authorized Multiquip supply channels, 1569491490 is the correct part for this application — verify your model code before ordering to confirm fitment.

Key Features

• Genuine OEM Hardware Grade — Manufactured to the same thread pitch, length, and material specification as the original stud, ensuring proper torque retention at exhaust manifold operating temperatures.
• Direct Bolt-In Replacement — Threads directly into the engine block and accepts the original manifold flange and nut without rework or modification to the mounting surface.
• Confirmed Fitment for DLW300ES Series — Compatible with DLW300ES, DLW300ESA, and DLW300ESA1 diesel light welder/generator models.
• Maintains Exhaust Seal Integrity — A properly installed manifold stud keeps clamping force even across the exhaust flange, preventing exhaust gas leaks that can affect engine performance and operator safety.
• Exhaust System Safety — Failed or broken exhaust manifold studs can allow hot exhaust gases to escape near the engine block, making timely replacement important for safe machine operation.

The exhaust manifold stud is a threaded fastener that anchors the exhaust manifold firmly against the engine block, allowing exhaust gases to flow out of the engine cleanly and safely. When a stud stretches, corrodes, or breaks, the manifold can no longer seat correctly against the head or block, resulting in exhaust leaks, increased noise, and potential heat damage to surrounding components. Replacing a worn or broken stud restores proper clamping force and keeps the exhaust system sealed under the high thermal cycling conditions typical of diesel-powered welder/generator use.
