The Multiquip M1311400004 is a genuine OEM Inter-Cooler Pipe designed for DCA36SPXU4F and DCA45SSIU4F series super-silent diesel generators. As a factory-sourced component, it matches the original routing, diameter, and connection points of the charge-air circuit, ensuring a straight-forward installation with no fabrication or adaptation. This part is confirmed to fit the DCA36SPXU4F, DCA45SSIU4F, and DCA45SSIU4FC8 models, including 60Hz variants operated in rental and fleet applications. Sourcing the correct M1311400004 from DHS Equipment means you receive an authentic Multiquip part backed by OEM quality assurance.
Key Features
- Genuine OEM Charge-Air Integrity — Factory-sourced tubing maintains the correct internal bore and pressure rating required for turbocharged diesel charge-air delivery, preventing boost leaks that degrade generator output.
- Exact Routing and Connection Match — Replicates the original pipe geometry, end fittings, and clamp positions so the component seats correctly between the turbocharger and inter-cooler without rerouting hoses or brackets.
- Broad DCA Series Compatibility — Fits DCA36SPXU4F, DCA45SSIU4F, and DCA45SSIU4FC8 super-silent generator models, including 60Hz configurations used in rental fleet and commercial standby applications.
- Sustained Power Output Under Load — A sound inter-cooler pipe keeps intake air temperatures in spec, allowing the engine to produce rated power consistently; a cracked or collapsed pipe causes derating, rough running, and excessive exhaust temperatures.
- Fuel System and Emissions Compliance — Maintaining proper charge-air flow supports Tier 4 Final combustion efficiency and emissions compliance on DCA series units equipped with after-treatment systems.
The inter-cooler pipe is the conduit that carries compressed, heated air from the turbocharger outlet to the inter-cooler (charge-air cooler), and then routes the cooled, denser air onward to the engine's intake manifold. By reducing intake air temperature, the inter-cooler allows the engine to burn more fuel efficiently and produce its rated power output. When this pipe cracks, collapses, or its end connections loosen, boost pressure escapes, intake air temperature rises, and the engine loses power — often triggering fault codes or automatic derating on electronically controlled Tier 4 generator sets.
