The Multiquip 1686123480 is a genuine OEM Crankshaft Metal M designed for DLW300ES and DAC7000SS series diesel welders and generators. Sourced directly from Multiquip, this component meets the original engineering specifications of the equipment it serves. Confirmed fitment includes the DLW300ES, DAC7000SS, DAC7000SSA, and DAC7000SSW — making it a straightforward, no-guesswork replacement for operators running these machines. DHS Equipment stocks this part to help you get your equipment back in service with the correct OEM component the first time.
Key Features
- Genuine OEM Crankshaft Precision — Manufactured to the original dimensional tolerances required for correct crankshaft seating, journal clearances, and bearing alignment in these engines.
- Direct-Fit Replacement — Matches the original mounting geometry and interface points, allowing straightforward installation without machining or adaptation.
- Confirmed Fitment — Compatible with DLW300ES series diesel light welders and DAC7000SS, DAC7000SSA, and DAC7000SSW ultra-silent diesel generators.
- Restored Engine Output — A correctly functioning crankshaft maintains proper power stroke conversion and engine balance; a worn or damaged crankshaft causes vibration, bearing wear, and eventual engine failure.
- Critical Engine Integrity — As a core rotating component, correct crankshaft condition is essential to maintaining oil pressure, engine timing, and safe sustained operation of the generator or welder.
The crankshaft is the central rotating component of an internal combustion engine, responsible for converting the up-and-down motion of the pistons into the rotational force that drives the generator or welder output. It works in direct contact with the connecting rods and main bearings, making its dimensional accuracy critical to engine balance and longevity. When a crankshaft becomes worn, scored, or damaged, it can cause excessive vibration, loss of oil pressure, accelerated bearing failure, and ultimately a complete engine seizure if left unaddressed.
