Multiquip RE556879 Gasket

The Multiquip RE556879 Gasket is a genuine OEM component designed for the DCA Super-Silent generator series, including DCA70SSJU4F, DCA150SSJU4F, DCA180SSJU4F, DCA220SSJU4F, and DCA300SSJU4F models. As a factory-sourced part, it meets the original design specifications for the engine assembly it services, ensuring a correct, leak-free fit without guesswork. This gasket covers both standard and 60 Hz variants across multiple model revisions including 4F, 4F2, and 4F3 configurations. Order RE556879 with confidence knowing it is the same part your machine was built with from day one.

Key Features

• Genuine OEM Material Integrity — Manufactured to the original compound and thickness specification, delivering the compression seal performance the engine was engineered around.
• Drop-In Replacement — Matches the original bolt pattern and sealing surface geometry for straightforward installation without rework or shimming.
• Broad DCA Series Coverage — Fits DCA70SSJU4F, DCA150SSJU4F, DCA180SSJU4F, DCA220SSJU4F, and DCA300SSJU4F series Super-Silent generators across 4F, 4F2, and 4F3 revisions, including 60 Hz variants.
• Leak Prevention — A correctly seated gasket maintains the pressure boundary between mating surfaces, protecting engine efficiency and preventing fluid or exhaust contamination that leads to accelerated component wear.
• Fuel and Exhaust System Safety — A failed or degraded gasket on a diesel generator can allow exhaust gases or fuel to escape at the joint; using the correct OEM replacement directly addresses that risk.

A gasket creates a static seal between two mating engine or system surfaces, filling microscopic irregularities to prevent the escape of fluids, gases, or pressure under operating conditions. On a diesel-powered generator like the DCA Super-Silent series, gaskets are critical to maintaining combustion integrity, proper oil containment, and exhaust routing. When a gasket deteriorates, compresses unevenly, or fails, the resulting leak can cause loss of engine efficiency, contamination of adjacent components, or unsafe exhaust exposure — making timely replacement with the correct OEM part essential.
