BorgWarner 12639900004 Turbo | Navistar MaxxForce 7 6.4L | Remanufactured

BorgWarner B2UV-63 turbocharger, part number 12639900004, remanufactured by BorgWarner for Navistar MaxxForce 7 6.4L engines with EPA07 emissions. BorgWarner is the original equipment manufacturer for this turbocharger, and the reman work is done by BorgWarner rather than a third party. This is the single-turbocharger EPA07 application — EPA10 MaxxForce 7 engines use a two-stage compound turbo system and this unit will not serve them. [CONFIRM: actuator included / not included]

Compatibility & Fitment

• Engine: Navistar MaxxForce 7, 6.4 L, EPA07
• Equipment: International medium-duty trucks and buses

Fitment gate — this is the single-turbocharger EPA07 application. EPA10 MaxxForce 7 engines use a two-stage compound system with separate high-pressure and low-pressure turbochargers, and this unit does not replace either half of it. Confirm your emissions era before ordering.

Second fitment gate — read the part number off the turbo you are removing and match it before ordering. If your existing unit carries 176180, 177328 or 177539, this is the current replacement.

Installation note — BorgWarner specifies inspecting the air cleaner, air cleaner duct and exhaust manifold for foreign material before fitting, since debris left in those areas can damage the turbocharger immediately on startup. Remove old gasket material from the exhaust manifold and the oil supply and drain line flanges, and inspect both lines for cracking, kinks or restriction. Replace them if there is any doubt.

Conclusion

This is the BorgWarner B2UV-63 turbocharger for the EPA07 Navistar MaxxForce 7 6.4L, remanufactured by BorgWarner rather than a third party. It is the current revision, replacing three earlier part numbers. Confirm your engine is EPA07 rather than EPA10 before ordering, since the EPA10 engines use an entirely different two-stage turbo system.
