The Multiquip 1569423940 is a genuine OEM Crankshaft Metal 0.40MM Set designed for the DAC7000SS, DAC7000SSW, and DAC7000SSA ultra-silent diesel generator series, as well as the DLW300ES welder series. As a factory-sourced component, this bearing set is engineered to meet the exact dimensional and material tolerances specified for the engine's crankshaft journal, ensuring a correct fit without guesswork. Sourced directly through Multiquip's OEM supply chain, this is the same part used in original production — giving you confidence that it belongs in your machine. If you have questions about fitment for your specific unit, the DHS Equipment team is ready to help.
Key Features
- Undersized Bearing Precision: — The 0.40MM undersize specification is engineered to match re-machined crankshaft journal dimensions, ensuring correct oil clearance and bearing load distribution in the engine.
- Genuine OEM Construction: — Manufactured to Multiquip's original material and hardness specifications, this crankshaft metal set delivers the same structural integrity as the components installed at the factory.
- Direct Engine Application: — Designed to install into the correct bearing saddle positions within the engine block, following the same fitment procedure as the original bearing set.
- Confirmed Fitment: — Verified for use with DAC7000SS, DAC7000SSW, and DAC7000SSA ultra-silent diesel generators and the DLW300ES welder series.
- Engine Longevity After Reconditioning: — Using the correctly sized bearing set during a crank regrind service restores proper oil film thickness, protecting against premature wear, overheating, and engine failure after rebuild.
- Critical Safety Fit for Rotating Components: — Incorrect bearing clearance in a crankshaft assembly can cause catastrophic engine failure; using the correct OEM-specified undersize set is essential for safe, stable operation after engine reconditioning.
The crankshaft bearing set — also referred to as crankshaft metals — are precision-machined inserts that sit between the crankshaft journals and the engine block's bearing saddles. Their primary function is to maintain a controlled oil film that supports the rotating crankshaft, preventing metal-to-metal contact under load. When a crankshaft is reground to remove wear or scoring, the journal diameter is reduced by a set amount — in this case 0.40MM — and a matching undersized bearing set must be installed to restore the correct operating clearance. Installing the wrong size results in excessive play or binding, both of which lead to rapid bearing failure, oil pressure loss, and serious engine damage.
