FAQ

The HE431V (5350060 / 4955462) fits the 2005-2007 Cummins ISM02, ISL, ISM, ISME and QSM11 engines on CM875, including CPL8557 370HP. OE and interchange numbers include 5350060, 4045934RX, 4089600, 3781163, 4044006, 4045934, 4955462. If your number is not listed, send it with the old part's dataplate photo and we confirm the match before shipping.

Pneumatic. The VGT vanes are controlled by a boost-pressure-operated canister — no electronic actuator, no wiring harness, no ECM calibration required. If your turbo has an electronic actuator with a connector, you need the HE431VE instead.

The HE531V (2881992) is a larger turbo for higher-HP ISM/QSM11 applications (1999-2015). The HE431V is the smaller turbo for the CM875 platform at 370 HP. Both use pneumatic actuators. Match by part number.

Yes. Ships with the pneumatic VGT actuator and mounting gaskets.

Brand new, 100% new components, dynamically balanced. No core charge. One-year unlimited-mileage warranty.

Yes. US stock, volume pricing for shops, fleets, transit agencies, and distributors.

HE431V VGT for Cummins ISM and ISL: The CM875 Platform Turbo

The HE431V serves the Cummins ISM and ISL engines during the CM875 era (2005-2007). It is a VGT turbo with a pneumatic actuator — not electronic — which makes it simpler to diagnose and install than the later electronic VGT turbos (HE400VG, HE451VE). If your engine has a pneumatic canister on the turbo instead of an electronic box with a wiring harness, this is likely your turbo.

HE431V vs HE431VE vs HE531V on the ISM

Cummins used several VGT turbos on the ISM/QSM11 platform across different model years:

TurboActuatorPlatformYears
HE431V (this page)PneumaticCM8752005-2007
HE431VE12V electronicCM21502007-2013 (ISC/ISL)
HE531V/HE531VEPneumaticVarious1999-2015 (ISM/QSM11)

The quickest way to identify your turbo: if the actuator is a pneumatic canister with no wiring harness, you have either the HE431V or the HE531V. The HE531V is a larger turbo for higher-HP ISM applications. If the actuator is an electronic box with a connector, you have the HE431VE or HE400VG series. Always confirm by part number.

Common failure modes

  • Pneumatic actuator diaphragm failure — the canister diaphragm cracks, causing stuck vanes (open or closed). Test with regulated air supply.
  • Vane ring soot buildup — especially common on buses and vocational trucks with frequent stop-start duty cycles.
  • Bearing wear — shaft play at 200k-400k miles. Oil past seals, rising EGT.

Cross Reference Numbers

This turbocharger replaces the following OE and interchange numbers:

  • 5350060
  • 4045934RX
  • 4089600
  • 3781163
  • 4044006
  • 4045934
  • 4955462

Related configuration: HE431VE 4047231 with electronic actuator.

Installation and Care

  • Find out why the old turbo failed before installing the new one. Oil starvation or contaminated oil will destroy the replacement the same way.
  • Change the engine oil and filter. Flush or replace the oil feed line.
  • Replace the exhaust manifold and oil drain gaskets. Prime the turbo with clean oil before startup.
  • Connect the pneumatic actuator reference hose and verify VGT vane movement before loading the engine.
  • Idle 3-5 minutes and verify VGT vane movement by watching the actuator rod respond to boost changes.
