International MaxxForce DT / DT466 B2FS Low-Pressure Turbocharger | BorgWarner 12749900075 Remanufactured
This is the BorgWarner 12749900075, the B2FS low pressure stage turbocharger for the two stage turbo system on the EPA10 International MaxxForce DT (DT466) 7.6L inline six, remanufactured by BorgWarner. It is the larger turbo of the pair, and catalogs carry it as the DT466 standard torque (DT466ST) unit. The new version of the same turbo is BorgWarner 12749880075. It replaces Navistar 1882866C1, 1889487C91 to C94, 1899113C1 to C3, 1899113C91 to C93, 5010936R90 to R93 and 5010937R1, and the older BorgWarner numbers 179323 and 179510.
This listing is the low pressure turbo only. The high pressure stage is a separate turbo, and catalogs pair this one with BorgWarner 11559880047 new or 11559900047 remanufactured. The MaxxForce DT also used a second low pressure turbo with a close number, 12749880076 (Navistar 1889489, 1891335 and 5010934), so match the number on the tag. Two catalogs date this turbo 2010 to 2012 and another 2011 to 2013. When one stage fails from oil starvation or debris, check the other stage before the truck goes back to work. A refundable core applies, so keep the old turbo complete.

Find out why the old turbo failed before this one goes on. Check the oil feed and drain lines for coking or restriction, change the engine oil and filter, inspect the piping between the two stages and the charge air cooler for oil and debris, and pre-oil the turbo before the first start. Inspect the high pressure stage while the system is apart.
