Excessive shaft endplay allows the rotating assembly to contact the housing, causing compressor wheel degradation, pressurized oil blow-by past the dynamic piston ring seals, and severe boost leakage. This manifests as heavy black smoke under acceleration, high exhaust gas temperatures (EGTs), and critical loss of grade-climbing power.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct bolt-on unit utilizes a heat-resistant \u003cstrong\u003eK418 alloy\u003c\/strong\u003e turbine wheel engineered to survive continuous high-thermal loading without blade deflection or micro-cracking. Featuring a 72.72 mm inducer and 64.06 mm 10-blade exducer, paired with a precision-machined 6+6 blade cast aluminum compressor wheel (59.2 mm inducer \/ 82.04 mm exducer, 52 trim), this turbocharger delivers factory airflow efficiency and transient boost response. The core features heavy-duty bronze hydrodynamic journal bearings and a 360-degree thrust collar assembly fed via standard oil-cooled galleries, matching OEM oil feed and drain port patterns without housing clocking or manifold adapter plates.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Turbocharger\u003c\/li\u003e\n  \u003cli\u003e1 Turbine Inlet Flange Gasket\u003c\/li\u003e\n  \u003cli\u003e2 Oil Line Gaskets\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100 style=\" border-collapse: collapse border: solid font-size: min-width:\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e1993-2001 International 4700,4900\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eDT466, DT466E, I530E \/ 4000-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e175-275 hp \/ 430-800 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e1826344C93, 1826344C91, 1826344092, 1825632C93, 1825632C91, 1825632RX1, 2506765C91, 1806077C91, 1806078C91, 1806079C91, 4307268R91, 409770-0019, 409770-0020, 409770-0021, 409770-0022, 409770-5019, 409770-5020, 409770-5021, 409770-5022, 466409-0, 684663C92, 684937C91, 691020C91, 691059C91, 691409C91, 691409C92, 735095C91, 735270C91\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1993-2001 International 4700 Medium Duty Truck (7.6L DT466 \/ DT466E, 8.7L DT530 \/ I530E)\u003c\/li\u003e\n  \u003cli\u003e1993-2001 International 4900 Heavy Duty Truck (7.6L DT466 \/ DT466E, 8.7L DT530 \/ I530E)\u003c\/li\u003e\n  \u003cli\u003eNavistar DT408P, DT466P, DT466E, and I530E commercial diesel applications up to 275 HP\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the 4000-Series 4700,4900?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1993-2001 International 4700,4900 equipped with the \u003cstrong\u003eDT466\u003c\/strong\u003e, \u003cstrong\u003eDT466E\u003c\/strong\u003e, or \u003cstrong\u003eI530E\u003c\/strong\u003e engine; always verify your current turbo tag against listed OEM part numbers to confirm precise housing match.\u003c\/p\u003e\n\n\u003ch4\u003eWhat pre-installation steps are critical to prevent immediate turbo failure?\u003c\/h4\u003e\n\u003cp\u003eFlush or replace the oil feed line, change engine oil and filter, inspect the charge air piping for debris, and manually pre-lube the center housing with clean oil prior to initial crank.\u003c\/p\u003e\n\n\u003ch3\u003eThe International Commercial Fleet Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe GCWR medium-duty hauling, municipal routes, and sustained highway operation, this turbocharger restores the payload torque and operational reliability fleet operators demand.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67610967310584,"sku":"DS-ECLZUV4QY","price":320.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/turbocharger-gta3776b-gta3782b-for-international-4700-4900-1993-2001-7-6l-8-7l-1.jpg?v=1791567049","url":"https:\/\/performancechiptuning.com\/fr\/products\/turbocharger-gta3776b-gta3782b-for-international-4700-4900-1993-2001-7-6l-8-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
