This is the Garrett 704604-5011S, a new GT4702 turbocharger for the Caterpillar 3406E 14.6L truck engine and the single-turbo C15 that followed it, the 6NZ and 9NZ engines. It is a complete new Garrett turbo, not a rebuild. It replaces Cat 0R7923, 0R7310, 0R7299, 160-6201, 166-6752, 167-9271 and 196-5951, and catalogs cross it to the BorgWarner S410G 177148. Catalogs list the Cat 0R7923 group for 475 to 550 hp. Two of them date it to 1994 through 2007 engines, and three also name the 3406C.

We list two new turbos for this Cat number group: this Garrett and the BorgWarner 177148. Catalogs cross them to each other. Two catalogs also show the Garrett 704604-0011 in place of the earlier 3406E numbers Cat 0R7201, 0R7223 and 146-4328. The BorgWarner page carries the rest of the earlier 3406E Cat numbers that catalogs tie to this group. The 3406B turbo on our site is the S4DS 178063, which replaces a different set of Cat numbers. The twin-turbo C15 ACERT takes separate high pressure and low pressure turbos with their own Cat numbers. Heavy truck turbos are matched by the number on the turbo tag, not by engine model alone. Low boost, oil in the charge pipes, shaft play and a wheel that has rubbed the housing are the usual reasons for replacement.

Frequently Asked Questions

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

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 704604-5011S replace?

Cat 0R7923, 196-5951, 0R7310, 0R7299, 160-6201, 166-6752 and 167-9271. Two catalogs also show it in place of Cat 0R7201, 0R7223 and 146-4328. If your tag shows a different Cat or Garrett number, call us and we will check it.

Will it fit a C15 ACERT with twin turbos?

This GT4702 is listed for the 3406E and the single-turbo C15. The twin-turbo C15 ACERT takes separate high pressure and low pressure turbos with their own Cat numbers, such as the Garrett 741154-5011S high pressure turbo.

My old turbo has a Garrett 704604 tag. Is this the replacement?

If the tag reads 704604-0007 or 704604-0011, or Cat 0R7923 or 196-5951, yes. A tag that reads 704604-0006 is a different turbo in two catalogs, and catalogs do not settle the other dash numbers. For those, or if the tag is gone, call 530-668-0818 with your engine serial number and horsepower rating.
