Multiquip 0041220000 Flat Washer

The Multiquip 0041220000 Flat Washer is a genuine OEM component designed for the DCA Super-Silent and Ultra-Silent generator series, including DCA70, DCA125, DCA150, DCA180, DCA220, DCA250, DCA300, DCA400, DCA500, DCA600, and DCA800 models, as well as select NGA Super-Silent generator models. As a genuine Multiquip OEM part, the part meets the exact material and dimensional specifications called out in the original build. With fitment spanning the full DCA generator lineup, this flat washer is a high-volume service item worth keeping in stock for planned maintenance and unexpected repairs alike.

Key Features

• Genuine OEM Material Specification — Manufactured to the exact thickness, inner diameter, and outer diameter called out in Multiquip's original engineering documents, ensuring consistent clamping load and surface distribution.
• Drop-In Hardware Fit — Matches the fastener sizing and seating geometry used throughout the DCA generator assembly, so it installs directly without modification to surrounding hardware.
• Broad DCA Series Coverage — Fits DCA70, DCA125, DCA150, DCA180, DCA220, DCA250, DCA300, DCA400, DCA500, DCA600, and DCA800 series generators, as well as select NGA Super-Silent models, making it a versatile stock item across a mixed fleet.
• Consistent Load Distribution — A correctly sized flat washer spreads fastener load evenly across the mating surface, protecting generator housings and structural panels from stress concentrations that can crack or deform over time.
• Supports Scheduled Fastener Service — Replacing washers during routine torque inspections and panel service intervals maintains joint integrity on high-vibration generator applications where hardware fatigue is accelerated.

A flat washer serves as a load-distributing interface between a fastener — bolt head or nut — and the surface it bears against. By spreading clamping force over a wider area, it prevents the fastener from pulling through or deforming softer materials and reduces surface wear at the joint. On large diesel generators like the DCA series, where engine vibration and thermal cycling continuously stress fastened connections, correctly specified washers are essential to maintaining joint torque and structural integrity. A missing or undersized washer can allow fasteners to loosen prematurely, leading to panel movement, misalignment, or accelerated wear of the components being secured.
