This is the Alliant Power AP90960, a Holset HE500VG style variable geometry turbocharger remanufactured by Alliant Power and supplied with the electronic actuator. It is built for the Cummins ISX15 (CM871) at the EPA07 emissions level and replaces Cummins 4309076. Many catalogs still list this turbo as the HE561VE. A refundable core applies.

Catalogs also list Cummins 4309076 as 2881997, 2881785, 4955425 and 4956010, and for CPL 2732. The actuator supplied replaces Cummins 6378270 (also listed as 4034289), a 12 volt unit. The EPA07 ISX15 used several different turbochargers under the same model names: Alliant Power AP90962 replaces Cummins 4309077 and is not the same part. Go by the number on the old turbo, not the year.

Specifications

Fits / Applications

• Cummins ISX15 (CM871), EPA07 emissions level, about 2007 to 2010
• Engines built with Cummins turbo 4309076, also listed as 2881997, 2881785, 4955425 and 4956010 (catalogs list CPL 2732)
• Supplied with the electronic actuator, which replaces Cummins 6378270 (12 V)
• Not the same turbo as Alliant Power AP90962 (Cummins 4309077): match by engine serial number (ESN) and the old turbo’s data plate

Prime the turbo with clean engine oil before the first start, fit new oil feed and drain gaskets, and check the oil feed line, the drain and the charge air cooler for debris from the old turbo. Find out why the old turbo failed before this one goes on.
