Yes, it was made for the Cummins ISB3.9, and 1 more listed under compatible equipment. Check the old turbocharger is marked 3769718 or one of the cross references, because makers change parts between serial ranges.
On the Cummins ISB3.9, 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.
A little radial play is normal on journal bearing turbos. Wheels touching the housing, or any noticeable end float, are not.
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.
No. It is an aftermarket turbocharger made to replace the Cummins 3769718. It is not made by the original manufacturer; the number only shows what it replaces.
