Multiquip 6210612811 Oil Cooler Gasket DCA400SSK S6D140F-2

The Multiquip 6210612811 is a genuine OEM Oil Cooler Gasket DCA400SSK S6D140F-2 designed for the DCA400SSK ultra-silent diesel generator. As a direct OEM component, this gasket is manufactured to the exact material and dimensional specifications required by the S6D140F-2 engine, ensuring a leak-free seal between the oil cooler and the engine block. Sourced directly through Multiquip's authorized parts network, 6210612811 is the correct replacement for DCA400SSK units requiring oil cooler service. DHS Equipment supplies this part as a stocked genuine OEM item, so you can get your generator back in service without compromise.

Key Features

• OEM-Grade Sealing Material — Manufactured to the precise compression and material grade required for oil cooler interfaces on the S6D140F-2 engine, maintaining oil pressure integrity under sustained operating temperatures.
• Direct Drop-In Replacement — Engineered to match the original mounting profile and bolt pattern of the DCA400SSK oil cooler assembly, requiring no trimming or modification during installation.
• Confirmed Fitment for DCA400SSK — Specifically validated for the Multiquip DCA400SSK ultra-silent diesel generator equipped with the Komatsu S6D140F-2 engine.
• Prevents Oil Contamination and Coolant Crossover — A properly seated oil cooler gasket keeps engine oil and coolant circuits isolated, protecting the engine from internal fluid mixing that can cause rapid wear or catastrophic failure.
• Critical Fuel System Safety Boundary — In diesel generator applications, a compromised oil cooler gasket can allow coolant ingestion into the oil circuit, leading to bearing failure and unplanned generator shutdown — making this a safety-critical service item.

The oil cooler gasket forms a pressure-tight seal between the oil cooler core and the engine block, allowing engine oil to pass through the cooler and shed heat without mixing with the engine coolant circuit. On heavy-duty diesel engines like the S6D140F-2, this component operates under continuous thermal cycling and elevated oil pressure, making gasket integrity essential to long-term engine health. When this gasket deteriorates or fails, oil and coolant can cross-contaminate, leading to milky oil, overheating, accelerated bearing wear, and potential engine damage if not addressed promptly.
