International MaxxForce DT / DT466 B2UV Turbocharger with Actuator | BorgWarner 12639880001 New (1881102C91)
This is the BorgWarner 12639880001, a new B2UV variable geometry turbocharger. Catalogs also call it the BV63. It is the mid mount turbo for the International MaxxForce DT and DT466 7.6L inline six, the version with the 70 mm aluminum compressor wheel, listed at about 245 hp (180 kW), and it comes as a complete unit with the electronic actuator fitted. It is a new turbo, not a rebuild. BorgWarner’s remanufactured version of the same turbo is 12639900001. Three catalogs list it for 2005 to 2010 model years. It replaces Navistar 1832666C91, 1850493C91, 1876116C91 to C96, 1881102C91 to C93, 1881104C91 to C93 and 5010720R91 to R93.
Two other mid mount B2UV turbos carry close numbers and look alike. BorgWarner 12639880002 (Navistar 1876118, 1881105 and 1881106) is the same engine’s turbo with a 76 mm titanium compressor wheel, and 12639880003 (Navistar 1877634 and 1881107) is the one catalogs list for the MaxxForce 9 and DT570 9.3L. Each has its own Navistar numbers, so match the number on your turbo tag before you order: this one is the 12639880001 family.

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, check the air filter and intake piping for dirt tracks, and pre-oil the turbo before the first start. Clear and recheck any boost or actuator fault codes after the install. Catalogs list the Alliant Power AP0170 turbo installation kit for this turbo, sold separately.
