This is the Alliant Power AP90942, a BorgWarner B2UV variable geometry turbocharger for the International A26 engine, remanufactured by Alliant Power. It is a complete turbo with the electronic actuator already fitted. It replaces Navistar 2517623C91 through 2517623C96, 5012032R91, 5012032R92 and 7099274C91 through 7099274C94, and BorgWarner 12769700027 and 12769880027.

Low boost, a boost or actuator fault code, oil in the charge pipes, shaft play or a turbo that whistles or howls under load are the usual reasons this unit comes off. On a variable geometry turbo, soot in the vanes and a failed actuator give the same low power complaint, so check for exhaust leaks, a split charge air cooler and a blocked aftertreatment system before you condemn the turbo. A refundable core applies to this remanufactured unit.

Find out why the old turbo failed before you fit this one. Change the engine oil and filter, check the oil feed and drain lines for restriction, prime the turbo with clean oil, and clean or replace the charge air cooler if the old turbo passed oil or broke up. Follow the truck maker’s procedure for the actuator after fitting.
