The Multiquip 1156390030 is a genuine OEM Bolt designed for the DCA ultra-silent diesel generator series, including DCA25SSIU, DCA25SSI, DCA25SSI2, DCA60SSI2, DCA25SSAI, DCA25SSIU-GEER, and DCA60SSAI models. As a direct OEM replacement, this bolt is manufactured to the exact specifications required by Multiquip for use in these generator units. Sourcing the correct hardware matters on equipment where structural integrity and vibration resistance are critical — an undersized or incorrect bolt can compromise torque retention and overall assembly stability. DHS Equipment stocks this part to help you get your generator back in service with confidence.
Key Features
- OEM-Grade Hardware Specification — Manufactured to Multiquip's exact thread pitch, grade, and dimensional requirements for the DCA ultra-silent generator series, ensuring correct clamping force and torque retention.
- Direct Drop-In Replacement — Engineered to seat and torque exactly as the original, with no reworking of mating components or mounting points required during installation.
- Broad DCA Series Compatibility — Confirmed fitment across DCA25SSIU, DCA25SSI, DCA25SSI2, DCA60SSI2, DCA25SSAI, DCA25SSIU-GEER, and DCA60SSAI generator models.
- Vibration and Load Resistance — Correct fastener grade ensures the bolt maintains its clamp load under the continuous vibration and thermal cycling typical of diesel generator operation, preventing loosening over time.
- Structural Assembly Integrity — Using the specified OEM bolt preserves the designed clamping characteristics of the assembly, protecting surrounding components from stress caused by improper fastener substitutions.
A bolt in a diesel generator assembly does far more than simply hold components together — it is engineered to maintain a precise clamping force across a specific joint, resisting vibration-induced loosening and thermal expansion over thousands of operating hours. In generator applications, where panels, mounts, and mechanical enclosures are subject to constant engine vibration, an incorrect or worn fastener can allow movement that damages mating surfaces or causes misalignment of critical components. Replacing a failed or missing bolt with the correct OEM part, such as Multiquip 1156390030, ensures the assembly performs as originally designed and prevents cascading hardware issues.
