Multiquip C1367700304 Lock Plate

The Multiquip C1367700304 Lock Plate is a genuine OEM component designed for the DCA-series ultra-silent diesel generator lineup, including DCA250SSI, DCA300SSC, DCA400SSI, DCA600SSV, DCA800SSK2, and DCA1100SSC models. As a direct Multiquip OEM part, the part is manufactured to the same specification as the original, ensuring correct fitment without guesswork. This lock plate is compatible across a wide range of DCA-series configurations, including Tier 4 variants such as the DCA400SSI4F, DCA400SSI4F3, DCA600SSV4F3, and related sub-variants. Sourcing the correct OEM lock plate matters — an improperly fitting or worn plate can compromise the mechanical integrity of the assembly it secures.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original specification, delivering the correct material grade and dimensional accuracy expected of a structural retention component.
• Direct Drop-In Replacement — Engineered to seat and secure exactly as the original, with no filing, bending, or adaptation required during installation.
• Broad DCA-Series Compatibility — Fits DCA250SSI, DCA300SSC, DCA400SSI, DCA600SSV, DCA800SSK2, DCA1100SSC, and associated Tier 4 and ultra-silent variants.
• Structural Retention Integrity — Keeps fasteners and mating components positively locked in position, preventing loosening under the vibration loads common during generator operation.
• Supports Safe Generator Operation — A correctly installed lock plate prevents unintended fastener movement in critical assemblies, supporting consistent and safe machine function.

A lock plate is a mechanical retention device used to prevent fasteners or rotating components from backing out or shifting during operation. In diesel generator applications like the DCA-series, equipment is subject to continuous vibration and thermal cycling that can cause conventional fasteners to loosen over time. The lock plate engages with the fastener or adjacent hardware to hold it firmly in place, maintaining the integrity of the assembly it secures. When a lock plate becomes worn, bent, or damaged, it can no longer reliably prevent movement, which may lead to component loosening and potential mechanical failure within the generator system.
