Where it is used
Made for the Cummins 6CT 8.3 litre engines.

Yes, it is a direct replacement for the Cummins 3535635 with the same fitting.
Often as long as the engine, 8,000 hours or more, when the oil and air filters are kept on schedule. Most turbos fail early from oil or dirt problems, not age.
Blue or black smoke, a whistle or siren noise, loss of power, oil in the intake or exhaust, or the shaft rubbing the housing.
Most failures come from oil starvation, dirty oil, or something passing through the wheels. Find the cause first: a blocked oil feed or dirty air path will kill the new turbocharger too.
A little radial play is normal on journal bearing turbos. Wheels touching the housing, or any noticeable end float, are not.
No. It is an aftermarket turbocharger made to replace the Cummins 3535635. It is not made by the original manufacturer; the number only shows what it replaces.
