As a factory-sourced component, it meets the exact dimensional and material tolerances required by Multiquip for proper crankshaft alignment and retention. This collar is a direct-fit replacement, ensuring it seats correctly without rework or modification to surrounding components. If you are servicing a DAC super-silent diesel generator or a DLW300ES diesel light welder, part number 1584123250 is the correct OEM specification collar for the application.

Key Features

• Exact OEM Dimensional Tolerancing — Manufactured to Multiquip's original specifications, this collar delivers the precise bore diameter and collar depth needed to correctly position and secure the crankshaft in supported generator and welder models.
• Direct-Fit Installation — Engineered to seat directly onto the crankshaft journal of compatible DAC and DLW series units, aligning with existing keyways and fastener positions without alteration.
• Broad Series Fitment — Confirmed compatible with DA7000SSA2, DA7000SSA2GH, DAC7000SS, DAC7000SSW, DAC7000SSA, and DLW300ES series diesel-powered generators and welders.
• Crankshaft Integrity Protection — A correctly fitted collar maintains proper crankshaft end-play and rotational alignment, preventing premature wear on bearings and seals throughout the drivetrain.
• Genuine OEM Sourcing — Supplied as an authentic Multiquip OEM part, so the material grade, hardness, and geometry match the original component removed from the machine.

The crankshaft collar is a precision retention component mounted on the crankshaft to control its axial position and prevent unwanted lateral movement within the engine or power unit. It works in conjunction with bearings and seals to keep the crankshaft centered and stable during operation, which is essential for consistent power transfer to connected generator or welder components. When this collar wears, cracks, or loses its fit, it can cause excessive crankshaft play, accelerated bearing wear, oil seal failure, and ultimately loss of output performance in the machine.
