HE431VE 4047231 4955533 Turbocharger for Cummins ISC 8.3L ISL 8.9L

The HE431VE is the Holset VGT turbocharger for the Cummins ISC 8.3L and ISL 8.9L engines, covering 2007-2013 model years on the CM2150 platform. This is a variable-geometry turbo with a 12V electronic actuator that controls the vane ring for boost optimization across the full RPM range. The HE431VE is used in medium-duty trucks (Freightliner M2, International, Kenworth T270/T370), school buses, motorhomes, and vocational applications. This listing is for the turbo without the electronic actuator. If your existing actuator tests good, reuse it. Built new with all new components, dynamically balanced, ships with gaskets. We supply shops, fleets, and distributors.

FAQ

The HE431VE (4047231 / 4955533) fits the 2007-2013 Cummins ISC 8-3L and ISL 8-9L engines on CM2150. OE and interchange numbers include 4047231, 4047232, 4047233, 4047234, 4047235, 4047236, 4047290, 2839565, 2839573, 2839574, 4955533, 4955534, 4955692, 4955693, 5354629. If your number is not listed, send it with the old part's dataplate photo and we confirm the match before shipping.

No. The HE400VG (4352565RX) is a different turbo used on later-model ISL/ISC engines. Different compressor cover, different actuator mount, different vane ring. They do not interchange. Match by part number on the turbo nameplate.

No. This listing is the turbo assembly only, without the 12V electronic actuator. Reuse your existing actuator if functional and run ECM calibration after install. Contact us if you need both components.

HE431VE VGT Turbo for Cummins ISC 8.3L and ISL 8.9L

The HE431VE is one of the most common VGT turbos in the medium-duty segment. It serves the ISC and ISL engines from 2007-2013 in everything from delivery trucks to school buses. Understanding the difference between the HE431VE and the HE400VG (4352565RX) — both used on the ISL/ISC platform — is important for ordering the right part.

HE431VE vs HE400VG on the ISL/ISC

Both turbos fit the ISL/ISC 8.9L engine family, but they are used on different model years and emissions tiers:

Key part #4047231 series4352565RX series

Check the turbo nameplate for the model designation and part number. The HE431VE and HE400VG have different compressor covers, different actuator mounts, and different vane ring configurations. They do not interchange.

Common ISC/ISL applications for the HE431VE

  • Freightliner M2 106/112 with ISC 8.3L or ISL 8.9L
  • International DuraStar, 4300/4400 series
  • Kenworth T270, T370
  • Peterbilt 330, 335, 340
  • School buses (IC Bus, Thomas Built) with ISC/ISL
  • Class A diesel motorhomes with ISL 8.9L

Failure modes

  • Vane ring sticking — soot accumulation jams the VGT vanes. Common in stop-and-go city duty where DPF regens are frequently interrupted. Results in derate codes and poor throttle response.
  • 12V actuator failure — the electronic actuator motor or internal gears fail. VGT position fault codes appear. Test the actuator response separately before replacing the turbo.
  • Bearing wear — shaft play develops over 200k-400k miles in medium-duty applications. Oil in intake, rising EGT.

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.
  • Transfer the existing electronic actuator only if it tests good, then run the required ECM VGT calibration.
  • Idle 3-5 minutes and verify VGT tracking via the ECM.
