Detroit Diesel Series 60 12.7L & Caterpillar C12 K31 Wastegated Turbocharger | BorgWarner 172743 New
This is the BorgWarner 172743, a new K31 wastegated turbocharger, not a rebuild, for the Detroit Diesel Series 60 12.7L. Catalogs list it for 1998 to 2007 engines, across the wastegated ratings up to 500 hp. It is BorgWarner’s replacement for the Garrett turbos these engines were built with: the GTA4294BNS, Garrett 714788-5001S, 714788-5003S, 714788-5005S and 714788-5006S, and the GTA4202BNS, Garrett 714792-5002S. That covers Detroit 23528065, 23525462, 23528052, 23526679, 23528059 and 23522190 and the other Detroit numbers in the cross reference list below. BorgWarner sells the same turbo as 172743BW.
Seller catalogs also list it for Caterpillar C12 truck engines, crossing to Caterpillar 0R7252, 0R7292, 0R7293, 0R7578, 0R7579, 10R1054 and 10R1055. Caterpillar turbos go by arrangement number, so confirm with us before ordering for a C12. This K31 is not listed for the Garrett TMF5502, which takes BorgWarner 171701 or 171702, or for the variable geometry Garrett GTA4502V turbos in the Garrett 758204 series. Heavy truck turbos are matched by the number on the turbo tag.
Confirm Fitment Before You Order
Series 60 turbos are matched by the number on the turbo tag, not by truck model or year. Catalogs list this K31 for the Garrett 714788 and 714792 series, including Detroit 23528065, 23525462, 23528052, 23526679, 23528059 and 23522190. Detroit 23535324 (Garrett 714788-5009S) is listed against it by one catalog only, so ask us first. For a Caterpillar C12, send the arrangement number or the Caterpillar turbo number: one catalog notes that some C12 arrangements also need a Caterpillar mounting kit. Send us your tag number and engine serial number. Call 530-668-0818 and we will confirm the exact match at no charge before anything ships.

Find out why the old turbo failed before you fit this one. Check the oil feed and drain lines for coke and restrictions, change the engine oil and filter, clean the charge air cooler and piping of oil and debris, check the wastegate signal line for cracks, and prime the turbo with clean oil before first start.

Frequently Asked Questions
Which engines does the BorgWarner 172743 fit?
The Detroit Diesel Series 60 12.7L built with a wastegated Garrett GTA4294BNS or GTA4202BNS turbo, listed by catalogs for 1998 to 2007. Catalogs also cross it to Caterpillar C12 truck turbos, which must be confirmed by arrangement number.
What is the difference between 172743 and 172743BW?
They are the same BorgWarner K31 turbo, sold under two BorgWarner numbers. Both replace the same Garrett and Detroit numbers.
Which Garrett turbos does it replace?
Catalogs list it for Garrett 714788-5001S, 714788-5003S, 714788-5005S and 714788-5006S (GTA4294BNS) and 714792-5002S (GTA4202BNS). That covers Detroit 23528065, 23528052, 23528059 and others. Give us your tag number so we can check it against the number on your engine.
Will it fit a Series 60 with the Garrett TMF5502 or a variable geometry turbo?
It is not listed for either. The TMF5502 takes BorgWarner 171701 (Detroit 23515635, 23515636 or 23516431) or 171702 (Detroit 23518588, 23518597 or 23523197), and the variable geometry GTA4502V has its own Garrett numbers. Call 530-668-0818 with your turbo tag number.
