Multiquip 0845054204 Collar

The Multiquip 0845054204 Collar is a genuine OEM component designed for the DCA Ultra-Silent and Super-Silent diesel generator series, including the DCA220SSK, DCA300SSC, DCA300SSK, DCA400SSI, DCA400SSK, DCA400SSV, DCA180SSK, DCA180SSV, DCA250SSI, and related variants. Sourced directly from Multiquip, this collar is manufactured to the same tolerances and material specifications as the original part installed at the factory. It is a direct-fit replacement that slots into position without modification, ensuring your generator is restored to its correct operating configuration. DHS Equipment stocks this part and ships it ready for installation on the full range of compatible DCA series units.

Key Features

• Genuine OEM Material Integrity — Manufactured to Multiquip's original dimensional and material specs, ensuring the collar holds its shape, seating, and grip under the mechanical loads typical of diesel generator operation.
• Exact-Fit Installation — Engineered to the same geometry as the original, this collar installs directly into compatible DCA series generator assemblies without reworking mating components.
• Broad DCA Series Compatibility — Confirmed fitment across the DCA220SSK, DCA300SSC, DCA300SSK, DCA400SSI, DCA400SSK, DCA400SSV, DCA180SSK, DCA250SSI, and multiple fleet-specific variants including GEER and SUNBELT configurations.
• Structural Retention — A correctly seated collar maintains precise alignment of adjoining components, preventing unwanted movement, wear, or loosening during extended generator run cycles.
• Genuine OEM Part Number — this part is the authoritative Multiquip part number for this collar, eliminating guesswork when ordering for DCA Ultra-Silent and Super-Silent units.

A collar is a mechanical retention and alignment component used to locate, secure, or constrain adjacent parts within an assembly — preventing axial or radial movement that would otherwise cause accelerated wear, misalignment, or component failure. In a diesel generator, collars are commonly used around shafts, housings, and structural connections where precise component positioning is critical to sustained output and safe operation. When a collar is worn, cracked, or missing, connected components can shift out of position, leading to vibration, uneven loading, and potential damage to surrounding parts.
