Understand Why original Turbocharger Failed: • Contaminated Oil? • Inlet/Outlet restriction? • Foreign Impact Damage? • Overheated? 2. Do Thorough Preparation: • Verify Turbo Part Number & Application is correct • Ensure correct gaskets are being used (Never use gasket sealant on oil inlet/outlet • Always replace oil/filters/Air Cleaner/Clean Air Cleaner Housing • Change the Oil Inlet line as a standard practice • Ensure that DPF Filter is clean and EGR Valve is functioning properly • Verify that there are no Exhaust Muffler restrictions • Crank the engine, without starting it to push out all old oil from oil feed Line • Check All Lines/Hoses for cracks or chafing • Check PVC system for restrictions and replace PVC Filter 3. Proper Installation is Critical: • Ensure that no dirt enters the oil or air paths of the Turbo • All old gasket material must be removed/check Flanges for flatness to create proper sealing surface • All O-rings and gaskets must be in place and correctly positioned • Although Turbo is Prelubed at factory, pour oil down the oil feed port before start up • Crank Engine for 15-20 seconds to prime oil feed to Turbo • When Engine is first started, let idle for 3-5 minutes to warm up while you check for oil/air leaks/ Coolant level • Verify Engine Oil Level is proper TECH Tips Made with FlippingBook RkJQdWJsaXNoZXIy MTEyNjY3NA== 30Turbo Solutions Top 3 Reasons for Turbocharger Failure MIDWESTWHEEL.COM IOWA MISSOURI DES MOINES 1436 E.
