The Multiquip 1586122970 Crankpin Metal 0.20MM Set is a genuine OEM undersized bearing set designed for DLW300ES series diesel light welders and DAC7000SS series ultra-silent diesel generators. As an authorized Multiquip OEM component, this set is manufactured to the exact material and dimensional tolerances required for an undersized crankpin journal, ensuring a correct fit during engine reconditioning. Confirmed fitment includes the DLW300ES, DLW300ESA, DLW300ESA1, DAC7000SS, DAC7000SSA, and DAC7000SSW. DHS Equipment stocks genuine Multiquip parts so you can source the right component with confidence.
Key Features
- Undersized OEM Bearing Metal: — Manufactured to a precise 0.20MM undersize specification, engineered for crankpin journals that have been machined during an engine rebuild or overhaul.
- Genuine Multiquip OEM Part: — Sourced directly from Multiquip, part number 1586122970 meets the exact material grade and bearing clearance requirements of the original engine design.
- Confirmed Fitment: — Compatible with DLW300ES, DLW300ESA, and DLW300ESA1 diesel light welders, as well as DAC7000SS, DAC7000SSA, and DAC7000SSW ultra-silent diesel generator models.
- Engine Rebuild Accuracy: — Using the correct undersize bearing set maintains proper oil film clearance at the crankpin, which directly affects bearing life and engine oil pressure after a crank grind.
- Drop-In Reconditioning Component: — Supplied as a matched set to simplify the rebuild process and ensure consistent clearance across the journal without additional sizing or shimming.
The crankpin bearing metals are the precision shell bearings that sit between the connecting rod big-end and the crankshaft crankpin journal. They carry the load of combustion forces while maintaining a thin film of pressurized oil to prevent metal-to-metal contact. When an engine's crankpin journal shows wear or scoring, it is machined to an undersized diameter, and a corresponding undersized bearing set — such as this 0.20MM set — must be installed to restore the correct running clearance. Using the wrong size bearing leads to excessive clearance, low oil pressure, and accelerated wear that can cause connecting rod or crankshaft failure.
