This is the BorgWarner 14969880000, a new S410SX turbocharger for the Caterpillar 3406E and C15. Three catalogs also list it for the C16. BorgWarner’s catalog lists it as an S410SX Big Bore Upgrade, and it is also sold as the S478 Big Cat. It has a 78 mm forged milled compressor wheel, a 96 mm turbine wheel, a 360 degree thrust bearing, a Cat style slip coupling compressor outlet and a 1.32 A/R turbine housing with no wastegate. It is an upgrade unit. It is not the number Caterpillar fitted at the factory.

Catalogs file it in place of the factory style wastegated S410G on these engines, BorgWarner 177148. It has no wastegate, so it is a change from the factory setup, not the factory-spec part. It is the smaller of two non-wastegated sister units: BorgWarner 14969880001 is the same S410SX with an 80 mm compressor wheel and a 1.58 A/R turbine housing. The part name gives this 78 mm unit a 600 to 650 hp rating. Heavy truck turbos are matched by the number on the turbo tag, so read your tag and call us before you order.

Specifications

Fits / Applications

• Caterpillar 3406E and C15, as a non-wastegated upgrade turbo
• Three catalogs also list it for the C16
• Catalogs that name the 3406 version say 3406E. Only one aftermarket catalog adds the 3406B and 3406C, so call first for those.
• Not listed as a replacement for either turbo on the twin-turbo C15 ACERT. Call first if your engine has two turbos.
• Catalogs file it in place of the factory style wastegated S410G, BorgWarner 177148. It is not the factory replacement number.
• Match by the number on your turbo tag
• Sister unit with an 80 mm compressor wheel and 1.58 A/R housing: BorgWarner 14969880001

Prime the turbo with clean engine oil before first start, fit new oil feed and drain gaskets, and check the air intake and charge air cooler for oil or debris left by the old turbo. This unit has no wastegate, so there is no actuator line to connect.
