Multiquip 5115300211 Crank Bearing Kit 0.25

The Multiquip 5115300211 is a genuine OEM Crank Bearing Kit 0.25 designed for the DCA25SSI, DCA25SSI2, DCA25SSIU, DCA25SSAI, and DCA25SSIU-GEER ultra-silent diesel generator series. As a direct Multiquip OEM component, this kit is manufactured to the same specifications as the original bearing set installed at the factory, ensuring a correct fit within the engine's crankshaft journal. Sourced directly through authorized Multiquip distribution channels, the part is the right choice when rebuilding or reconditioning the lower end of your DCA-series generator engine. DHS Equipment stocks genuine Multiquip OEM parts to help you get your equipment back to full operation with confidence.

Key Features

• Undersized OEM Bearing Grade — The 0.25mm undersize specification matches worn or reground crankshaft journals precisely, restoring correct oil clearance and bearing crush without improvisation.
• Genuine Multiquip OEM Kit — Manufactured to original equipment tolerances for the crankshaft bearing bores in Isuzu-powered DCA-series generators, so the bearing shells seat and load correctly from the first startup.
• Confirmed Fitment for DCA25 Series — Verified for DCA25SSI, DCA25SSI2, DCA25SSIU, DCA25SSAI, and DCA25SSIU-GEER ultra-silent diesel generators.
• Engine Rebuild Confidence — Using the correct undersize bearing kit during a crankshaft recondition prevents premature bearing failure, oil pressure loss, and accelerated wear that result from mismatched clearances.
• Critical Lubrication System Integrity — Properly fitted crank bearings maintain the oil film that protects the crankshaft at high load — a worn or incorrect bearing risks catastrophic engine damage and extended downtime on a revenue-generating generator asset.

The crank bearing kit provides the main and rod bearing shells that support the crankshaft within the engine block of your DCA-series generator. These bearings carry the full rotational load of the crankshaft and rely on a precise oil film to prevent metal-to-metal contact. When bearings wear beyond their service limits — or when a crankshaft is reground to remove scoring — an undersize bearing kit like the part is required to restore the correct running clearance. Neglecting worn crank bearings leads to dropping oil pressure, knocking, and ultimately engine seizure, making this kit a foundational component in any lower-end engine rebuild.
