The Multiquip 1586123910 is a genuine OEM Crankshaft Metal 0.20MM designed for DAC7000SS, DAC7000SSW, and DAC7000SSA ultra-silent diesel generators, as well as DLW300ES, DLW300ESA, and DLW300ESA1 diesel light welders. Sourced directly from Multiquip, this undersize bearing shell is manufactured to exact dimensional tolerances for engines that have undergone crankshaft regrinding to the 0.20MM undersize specification. Confirm your engine's crankshaft journal diameter and grind specification before ordering to ensure this is the correct undersize grade for your application.
Key Features
- Undersize-Specific Bearing Clearance — Engineered to the 0.20MM undersize specification, delivering the precise oil film clearance required after a crankshaft regrind to maintain correct bearing-to-journal contact.
- Genuine OEM Construction — A Multiquip-sourced OEM component, manufactured to the same material grade and dimensional standards as the original bearing metal installed at the factory.
- Direct-Fit Replacement — Sized and profiled to seat correctly in the original bearing housing without modification, allowing a straightforward engine rebuild installation.
- Broad DAC and DLW Series Fitment — Compatible with DAC7000SS, DAC7000SSW, and DAC7000SSA ultra-silent generator models, as well as DLW300ES, DLW300ESA, and DLW300ESA1 welder platforms.
- Engine Longevity After Rebuild — Using the correct undersize bearing metal restores proper lubrication and load distribution at the crankshaft journal, protecting the engine from premature wear following a regrind service.
A crankshaft metal — commonly called a bearing shell or rod/main bearing insert — sits between the crankshaft journal and its housing, creating a precision oil film that allows the crankshaft to rotate smoothly under load. When an engine is rebuilt and the crankshaft journals are reground to remove scoring or wear, standard-size bearing shells no longer provide the correct clearance, and an undersize bearing metal such as this 0.20MM grade is required to restore the proper fit. Using the wrong size bearing risks insufficient oil pressure, accelerated journal wear, and ultimately catastrophic engine failure, making correct undersize selection a critical step in any crankshaft rebuild procedure.
