Multiquip 8973524030 Oil Pan Gasket 4BD1

The Multiquip 8973524030 is a genuine OEM Oil Pan Gasket 4BD1 designed for the DCA40SSAI ultra-silent diesel generator. As a direct Multiquip OEM replacement, this gasket is manufactured to the exact material and dimensional specifications required by the 4BD1 engine, ensuring a proper seal between the oil pan and engine block. Sourced directly through authorized Multiquip supply channels, the part is the correct service part for DCA40SSAI units requiring oil pan gasket replacement.

Key Features

• OEM-Grade Sealing Material — Manufactured to the compression and chemical-resistance specifications of the 4BD1 engine, delivering an oil-tight seal under sustained operating temperatures and pressures.
• Direct Drop-In Replacement — Matches the original oil pan bolt pattern and sealing surface profile of the 4BD1 engine block, allowing straightforward installation without modification.
• Confirmed DCA40SSAI Fitment — Verified for use on the Multiquip DCA40SSAI ultra-silent diesel generator; always cross-reference your model code before ordering.
• Prevents Oil Loss and Engine Contamination — A properly seated oil pan gasket maintains the engine's lubrication system integrity; a failed or deteriorated gasket allows oil to escape, leading to low oil pressure and accelerated engine wear.
• Fuel and Oil Resistant Composition — Formulated to withstand continuous exposure to engine oil without swelling, cracking, or losing compression — critical for a generator running extended duty cycles.

The oil pan gasket forms the seal between the engine's oil pan and the bottom of the engine block, keeping engine oil contained within the lubrication circuit. On a diesel generator like the DCA40SSAI, maintaining that seal is essential — even a minor leak can reduce oil level, starve bearings and moving components of lubrication, and cause significant internal engine damage over time. When this gasket hardens, cracks, or is disturbed during service, replacing it with the correct OEM part ensures the seal is fully restored to specification.
