FAQ

Q: How do I verify this turbocharger will fit my Cummins engine?

A: Check the existing turbocharger on your engine for stamped part numbers. If the number matches 4051033, 4049358, 33500958, or 3537951, this unit is a direct replacement. Additionally, confirm your engine model is L360, L325, or Dcec series. If you are unsure, contact us with your engine serial number and current turbocharger part number for verification assistance.

Q: What installation precautions should I take?

A: Professional installation by a qualified diesel mechanic is strongly recommended. Before installation, ensure the engine oil supply line is clean and unrestricted. Always replace oil and oil filters when installing a new turbocharger to prevent contamination. Inspect the air intake system for debris and clean or replace air filters. Prime the turbocharger with clean engine oil through the oil inlet before starting the engine to prevent dry start damage.

Q: What maintenance is required for this turbocharger?

A: Regular maintenance includes checking boost pressure during operation, inspecting for oil leaks at connections, and listening for unusual noises. Follow the engine manufacturer’s recommended oil change intervals using the correct oil grade. Allow the engine to idle for 2-3 minutes before shutdown, especially after heavy operation, to allow the turbocharger to cool and prevent oil coking. Periodically check all mounting bolts and hose connections for tightness.
