What it does
Exhaust gas spins the turbine, which drives the compressor wheel on the same shaft and pushes more air into the engine. More air lets the engine burn more fuel cleanly, giving the rated power.
Where it is used
Made for the Cummins 6BTAA, 6BTA5.9 diesel engines and the Komatsu SA6D102 engine in PC220-7 and PC270-7 excavators. The full list is in the tables above.

Yes, it was made for the Cummins 6BTAA, and 2 more listed under compatible equipment. Check the old turbocharger is marked 3598036 or one of the cross references, because makers change parts between serial ranges.
On the Cummins 6BTAA, 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.
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.
No. It is an aftermarket turbocharger made to replace the Cummins 3598036. It is not made by the original manufacturer; the number only shows what it replaces.
