Common Holset HY35W 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 HY35W turbocharger.

Balancing Notes

The compressor wheel and turbine shaft are individually balanced. Balancing the assembled rotating assembly is recommended best practice.
