Multiquip 5115400211 Crank Bearing Kit 0.50

The Multiquip 5115400211 is a genuine OEM Crank Bearing Kit 0.50 designed for the DCA25SSI, DCA25SSI2, DCA25SSIU, DCA25SSAI, and DCA25SSIU-GEER ultra-silent diesel generator series. Sourced directly from Multiquip, this kit delivers the exact bearing specification required to restore crankshaft tolerances to original operating standards. The 0.50 undersize rating makes it the correct choice for engines that have undergone crankshaft journal grinding to that dimension. Confirm your engine's journal size before ordering to ensure this kit is the right match for your application.

Key Features

• Precision Undersize Specification: — Rated at 0.50 undersize to match reground crankshaft journals, ensuring correct oil film clearance and proper load distribution across the bearing surface.
• Genuine OEM Component: — Manufactured to Multiquip's original engineering specifications, delivering the same material hardness and dimensional accuracy as the factory-installed bearing set.
• Direct-Fit for DCA25SS Series Generators: — Engineered specifically for the DCA25SSI, DCA25SSI2, DCA25SSIU, DCA25SSAI, and DCA25SSIU-GEER, dropping into the engine block without modification.
• Restores Engine Performance After Crankshaft Service: — A correctly sized crank bearing maintains consistent oil pressure and smooth crankshaft rotation; worn or improperly sized bearings lead to knock, oil pressure loss, and accelerated engine wear.
• Engine Integrity and Longevity: — Using the correct undersize bearing after a journal grind is critical to preventing premature failure — an incorrect bearing size compromises the hydrodynamic oil film that protects the crankshaft under load.

The crankshaft bearings support the rotating crankshaft inside the engine block, allowing it to spin freely while carrying the mechanical loads generated during combustion. They rely on a thin film of pressurized oil to prevent metal-to-metal contact between the crankshaft journal and the bearing shell. When bearings wear or are damaged, oil pressure drops, knocking develops, and the crankshaft itself can sustain permanent damage. During an engine rebuild that involves crankshaft grinding, the journal diameter is reduced to a precise undersize — in this case 0.50 — and the replacement bearing kit must match that dimension exactly to restore proper clearance and protect the engine long-term.
