Turbo Oil Supply Hose Assembly S50 8.5L DDEC 3
Detroit Diesel

This high grade steel hose assembly is engineered to deliver a reliable oil feed to the turbocharger on S50 8.5L engines equipped with DDEC 3. The design features precision flared ends set at 45 degrees on both sides, with 5/8-18 UNF in fittings, which ensures secure, leak resistant connections in tight engine compartments. The stainless steel construction handles the elevated temperatures and aggressive oil environment found near the turbocharger, maintaining structural integrity and resisting fatigue over long service intervals. By routing oil directly to the turbine bearings, this assembly minimizes the risk of oil starvation during high boost, accelerating spool-up and protecting critical components from wear. The VMRS code 045-012-047 places this item within the turbo lubrication subsystem, supporting accurate maintenance planning and part replacement. Compatibility is aligned with the Detroit Diesel S50 8.5L family using DDEC 3 controls, making it a precise match for the OEM lubrication path rather than a generic retrofit. When installed correctly, the hose assembly supports consistent oil pressure, reduces vibration-induced wear on hose lines, and simplifies service with preconfigured end fittings that streamline installation during turbo maintenance or overhaul events. Cross references are limited, underscoring its targeted fitment in the specified platform.
