Cummins Turbochargers — part numbers

101 numbers covering complete turbochargers, cartridges, and the mounting, oil feed and drain hardware that goes with them. Applications run from the single-turbo B series engines through to the twin-turbo arrangements on the larger KTA families.

Turbocharger part numbers are among the least forgiving in this catalogue. A turbo is matched to a specific engine build — the compressor and turbine housing trim, the wastegate setting where fitted, and the mounting flange all vary between builds that share an engine name. The number stamped on the turbo nameplate is the reliable identifier. If it is legible, send it; if it is not, send photographs of the unit from several angles including both housings and the mounting face.

The failure question matters more here than in most categories. Turbochargers rarely fail on their own account. They fail because of oil supply problems, because of ingested debris, or because the engine was shut down hot without an idle period, and a new turbo fitted without addressing the cause will fail the same way. If you are replacing a turbo, tell us why the last one failed. Where the answer is oil-related we will quote the oil feed line and filter in the same enquiry as a matter of course.

On tier, we quote genuine and quality remanufactured units. Remanufactured turbochargers from a reputable rebuilder are a legitimate option and considerably cheaper; unbranded new units at prices that look too good generally are. As everywhere on this site, the tier is stated on the line.

For a quotation, send the turbo nameplate number where you have it, the engine serial and CPL, and photographs of the installed unit.
