The Multiquip 1G46023920 Crankshaft Metal 0.40 mm is a genuine OEM bearing shell designed for the DLW330X2 diesel light welder/generator. Sourced directly from Multiquip, this is an exact-specification undersize bearing metal engineered to restore crankshaft journal clearances to manufacturer tolerances during an engine rebuild. If your DLW330X2 is due for a crankshaft service or bottom-end overhaul, this 0.40 mm undersize shell is the correct OEM-specified component for the job.
Key Features
- OEM-Specified Bearing Grade — Manufactured to the exact material hardness and bearing overlay specification required for the DLW330X2 engine, ensuring correct oil film geometry at the crankshaft journal.
- 0.40 mm Undersize Dimension — Precisely ground to 0.40 mm undersize, matching reground crankshaft journals for a correct interference and clearance fit during engine reconditioning.
- Direct OEM Replacement — Part number 1G46023920 cross-references directly to the DLW330X2 engine assembly, dropping into position without additional machining or shimming.
- Supports Full Engine Rebuild Integrity — Using the correct undersize bearing shell maintains proper oil pressure at the crankshaft, which is critical to engine longevity and consistent generator output performance.
- Fits DLW330X2 Welder/Generator — Confirmed OEM fitment for the Multiquip DLW330X2 diesel light welder platform.
A crankshaft bearing metal — also called a bearing shell or main bearing insert — sits between the crankshaft journal and the engine block, creating a precision oil film that allows the crankshaft to rotate smoothly under load. When journals wear or are reground during a rebuild, an undersize bearing metal like this 0.40 mm shell is required to restore the correct clearance and maintain adequate oil pressure. Fitting the wrong size or a worn bearing shell causes oil pressure drop, accelerated journal wear, and can ultimately lead to catastrophic engine failure, making correct part selection critical during any bottom-end reconditioning.
