Common Holset HE351CW Failure Symptoms

If your 5.9L 24v Cummins turbo is showing any of these symptoms, a full rebuild is recommended:

• Wastegate actuator drift or stuck operation — overboost or underboost, inconsistent boost between runs
• Excessive shaft play or oil seal leakage — blue smoke at idle, oil residue in the intercooler piping, end-play beyond OEM tolerance
• Bearing failure — whining, grinding, or whistling that scales with RPM
• Loss of boost and reduced power — turbo not holding rated boost, sluggish acceleration, excess EGT

Advanced Rebuild Kit — Everything in One Box

This package supplies the rebuild components listed in What’s Included for the Holset HE351CW turbocharger.

Balancing Notes

This kit contains unassembled repair components. Compressor wheels and turbine shafts are individually balanced; balancing the completed rotating assembly is recommended best practice.
