Buy wp20596 - Genuine Cummins HE300VG/HE351VE Turbocharger Kit - 1 - wisentpartscenter.com

Description

The Genuine Cummins 4352330HX Turbocharger Kit is a variable geometry turbocharger (VGT) designed for compatible Cummins ISB 6.7L diesel engines. Part of the Holset HE300VG and HE351VE turbocharger family, it uses adjustable turbine geometry to control exhaust gas flow and boost pressure across different engine operating conditions. This turbocharger supports engine response, power delivery, and emissions-system operation in medium-duty trucks and commercial vehicles equipped with the corresponding Cummins engine configuration.

Key Functions

- Uses exhaust gas energy to compress intake air and increase engine boost pressure.
- Adjusts turbine geometry to improve boost response across varying engine speeds and loads.
- Supports engine torque and power delivery during acceleration and heavy loads.
- Helps regulate exhaust backpressure as part of the engine's emissions-control strategy.
- Works with the engine control system to maintain the required boost and turbocharger operating conditions.

Purpose of the Part

The Cummins Turbocharger uses exhaust gas energy to drive a turbine connected to a compressor, increasing the amount of air entering the engine's cylinders. Its variable geometry mechanism adjusts the turbine's effective flow area to provide responsive boost at lower engine speeds while maintaining efficient airflow under higher loads. The turbocharger also helps manage exhaust backpressure, supporting engine performance and the operation of the emissions-control system.

Issue Symptoms / When to Replace

A worn or malfunctioning variable geometry turbocharger can cause engine performance and boost-control problems. Common symptoms include:

- Reduced engine power or poor acceleration.
- Low or inconsistent boost pressure.
- Excessive black exhaust smoke under load.
- Check Engine light or turbocharger control faults.
- Unusual whining, grinding, or other turbocharger noises.
- Oil leakage or excessive oil consumption.
- Sticking variable geometry mechanism or restricted vane movement.

Similar symptoms can also result from a faulty electronic actuator, charge-air leaks, restricted intake or exhaust systems, damaged sensors, or lubrication problems. Diagnose the turbocharger and related components before replacement.

Brand Information

Cummins manufactures diesel engines and power systems for commercial vehicles, industrial equipment, and other heavy-duty applications. Holset turbochargers are produced by Cummins Turbo Technologies, which develops turbocharging systems for diesel engines. The HE300VG and HE351VE families use variable geometry technology to support boost control, engine response, and emissions performance.

Installation Notes

Before installing the Cummins Turbocharger, inspect the engine oil supply and drain lines for restrictions, contamination, or damage. Prime the turbocharger with clean engine oil before initial startup, and check the intake, exhaust, and charge-air systems for leaks or debris that could cause repeat failure. If an electronic actuator is being installed or transferred, follow the applicable Cummins service procedure for proper actuator installation and calibration.

How to Identify an OEM Part

Identify the Cummins Turbocharger using the Holset identification plate on the compressor housing, which lists the turbocharger assembly number, serial number, customer number, and model. Compare these details with the original turbocharger and confirm whether the replacement requires an HE300VG or HE351VE configuration. The electronic actuator, when present, may have its own separate identification plate.
