Mack's Auto Repair, LLC in Harahan is pleased to offer the remanufactured Holset HE351VE turbocharger to our customers for 2007 and current Cummins 6.7L diesel engine applications.  Each JASPER remanufactured Cummins 6.7L Holset turbo undergoes a three-step balancing process.   The turbine shaft/wheel assembly, and the compressor wheel, are individually balanced on a component balancer.  The rotating assembly, or center section, is then balanced on a high-speed VSR machine.  The center section is balanced at over 70,000 RPM.  They verify balance is at .05 grams per square inch or below for best operation and improved turbo life.
