HE431VE 4047231 VGT Turbo for Cummins ISC 8.3L ISL | New

HE431VE 4047231 VGT Turbocharger for Cummins ISC 8.3L ISL

HE431VE

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) fits the Cummins ISC 8.3L and ISL 8.9L engines on the CM2150 platform, 2007-2013 model years. OEM numbers include 4047231-4047236, 2839574, 2839565, 4955533, 4955534, 4955692, 4955693, and 5354629.

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.

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

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

Yes. US stock, volume pricing for shops, fleets, school districts, and distributors.

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:

Detail	HE431VE (this page)	HE400VG (4352565RX)
Years	2007-2013	Later model ISL/ISC
Platform	CM2150	Later CM platforms
Actuator voltage	12V	Varies
Key part #	4047231 series	4352565RX 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

This listing does not include the 12V actuator. Transfer your existing actuator if it tests good. Run ECM VGT calibration after install.
Replace exhaust manifold and oil drain gaskets (included).
Flush oil feed line. Prime turbo before startup.
Idle 3-5 minutes, verify VGT tracking via ECM.
