Frequently asked questions

Will it fit my Cummins ISF3.8 diesel engine?

Yes, it was made for the Cummins ISF3.8 diesel engine. Check the old turbocharger is marked 3772742 or one of the cross references, because makers change parts between serial ranges.

How often should I replace the turbocharger on my Cummins ISF3.8 diesel engine?

On the Cummins ISF3.8 diesel engine, 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.

What are the signs the turbocharger needs replacing?

Blue or black smoke, a whistle or siren noise, loss of power, oil in the intake or exhaust, or the shaft rubbing the housing.

Should I change the oil and filter as well?

Yes. Fit new oil and a new filter, and replace the oil feed and drain gaskets. Make sure the drain line is clear and runs downhill.

Is shaft play normal?

A little radial play is normal on journal bearing turbos. Wheels touching the housing, or any noticeable end float, are not.

Is this a genuine Cummins 3772742?

No. It is an aftermarket turbocharger made to replace the Cummins 3772742. It is not made by the original manufacturer; the number only shows what it replaces.
