Multiquip 1G07214506 Cylinder Head Cover Assembly

The Multiquip 1G07214506 Cylinder Head Cover Assembly is a genuine OEM component designed for the DLW400ES series diesel light welder generators. Sourced directly through Multiquip's authorized parts network, this assembly ensures an exact match to the original equipment specification — no guesswork on fitment or compatibility. If you're servicing a DLW400ES, DLW400ESA, or DLW400ESA1 unit, 1G07214506 is the correct OEM replacement to restore your machine to proper working order.

Key Features

• Genuine OEM Construction — Manufactured to the same tolerances and material standards as the original part, ensuring a correct seal and structural match at the cylinder head.
• Direct-Fit Assembly — Designed as a complete cylinder head cover assembly, it installs using the existing mounting points on DLW400ES series engines with no modification to hardware or mating surfaces.
• Confirmed DLW400ES Series Fitment — Compatible with DLW400ES, DLW400ESA, and DLW400ESA1 diesel light welder generator models.
• Engine Integrity Protection — A properly seated cylinder head cover keeps oil contained and contaminants out of the valve train, preventing accelerated wear and oil loss during operation.
• Fuel System and Oil Sealing Compliance — As a cover assembly on a diesel engine, maintaining a proper seal is critical to preventing oil leaks that could create fire hazards or damage adjacent electrical and fuel system components on the welder generator.

The cylinder head cover assembly sits atop the engine's cylinder head, enclosing the valve train and forming a sealed barrier that retains engine oil while blocking dirt, debris, and moisture from entering the upper engine. It plays a direct role in maintaining proper lubrication to the rocker arms and valves. When the cover or its gasket fails — through cracking, warping, or a compromised seal — oil leaks develop, valve train components are exposed to contamination, and engine performance deteriorates rapidly.
