This is the BorgWarner 177148, a new S410G (S400 family) wastegated turbocharger for the Caterpillar 3406E 14.6L truck engine and the single-turbo C15 that followed it, the 6NZ and 9NZ engines. Catalogs list it for 475 to 550 hp. Two catalogs date the turbo group to 1994 through 2007 engines, and three also name the 3406C. It is a complete new turbo, not a rebuild. It replaces Cat 0R7923, 0R7310, 0R7299, 0R7152, 0R7201, 0R7203, 0R7223, 0R6986, 0R6989, 124-3032, 124-3035, 136-6390, 137-4832, 141-8937, 141-8939, 146-4328, 160-6201, 166-6752, 167-9271 and 196-5951. It also takes the place of the earlier BorgWarner 169227 and 170354 and Garrett 466445-0015, 466445-0018, 466445-0021, 466445-0023, 471142-0003 and 471142-0005.

Two new turbos on our site cover this Cat number group: this BorgWarner S410G and the Garrett 704604-5011S. Catalogs cross them to each other and to Cat 0R7923 and 196-5951. The 3406E used other S410G turbos at other ratings, such as BorgWarner 174260 and 175963, so the Cat number decides it, not the engine model. The 3406B turbo on our site is the S4DS 178063, which replaces a different set of Cat numbers. The twin-turbo C15 ACERT uses a separate high pressure and low pressure turbo with their own Cat numbers. Heavy truck turbos are matched by the number on the turbo tag. Low boost, a sticking wastegate, oil in the charge pipes and shaft play are the usual reasons for replacement.

Specifications

Fits / Applications

• Caterpillar 3406E 14.6L truck engine, listed for 475 to 550 hp
• Caterpillar C15 single turbo, serial prefixes 6NZ and 9NZ, where the turbo tag crosses to Cat 0R7923 or 196-5951
• Three catalogs also list this turbo for the 3406C. On a 3406C, match the Cat number on the turbo tag.
• Two catalogs date this turbo group to 1994 through 2007 engines. Match the Cat number, not the year.
• Replaces Cat 0R7923, 0R7310, 0R7299, 160-6201, 166-6752, 167-9271 and 196-5951, plus the earlier 3406E numbers listed below
• Match by the number on your turbo tag

Find out why the old turbo failed before you fit this one. Check the oil feed and drain lines, change the engine oil and filter, clean the charge pipes and charge air cooler of oil and debris, check the wastegate line for leaks, and pre-oil the turbo through the feed port before the first start.

Frequently Asked Questions

Is the BorgWarner 177148 the same turbo as the Garrett 704604-5011S?

They are two makers’ turbos for the same Caterpillar numbers. Catalogs cross them to each other and to Cat 0R7923 and 196-5951, so either one replaces the other.

What Cat numbers does the 177148 replace?

Cat 0R7923, 0R7310, 0R7299, 0R7152, 0R7201, 0R7203, 0R7223, 0R6986, 0R6989, 124-3032, 124-3035, 136-6390, 137-4832, 141-8937, 141-8939, 146-4328, 160-6201, 166-6752, 167-9271 and 196-5951.

Will it fit a C15 ACERT with twin turbos?

This S410G is listed for the 3406E and the single-turbo C15. The twin-turbo C15 ACERT uses separate high pressure and low pressure turbos with their own Cat numbers, such as the Garrett 741154-5011S high pressure turbo.

How do I make sure it matches my engine?

Read the number off your turbo tag and compare the whole number to the list here. Dash numbers matter: Garrett 704604-0006, for one, is a different turbo in two catalogs. If the tag is unreadable, call 530-668-0818 with your engine serial number and horsepower rating.
