Product Details

This is a fully remanufactured Holset HE300VG Turbo Actuator, part number R8481772AA, found in 2013 - 2020 medium or heavy duty trucks with a 6.7L Cummins engine. Each actuator is completely remanufactured mechanically and electronically at our facility in Greenville, SC. We rebuild actuators with new OE ball bearings and new bushings. We correct all known issues on each circuit board using OE spec or better replacement components, and test each actuator on a turbocharger. Our actuators include the installation kit and gaskets for 6.7 Liter Cummins Engines.

Common Diagnostic Codes

If your exhaust brake is not functioning or you have any of the following codes you may have a faulty actuator.

  • U010C - No communication
  • P00AF - Boost control module performance
  • P003A - Boost control module exceeding learning limit

If your truck has an HE351VE Turbocharger and you would like to upgrade to an HE300VG Turbo Actuator, please text or call 800-547-2049.

Optional Calibrator Tool Rental

The actuator will require calibration to complete the re-installation. Calibration can be performed with any standard, capable tool including Cummins INSITE, Holset E-Tool, and various Snap-On, Matco, and Autel tools. We can include an optional calibration tool in the shipment of your actuator for an additional rental fee of $100. This calibration tool allows you to accomplish the entire installation process without a trip to the dealer or mechanic. Additionally, unlike other calibration procedures, our calibration tool will not require any changes to your custom tune. There will be an additional charge of $500 if the calibration tool is NOT returned to us within 15 calendar days of the shipment of this product.


  1. The purchase of this replacement turbo actuator requires your original "core" be shipped to Circuit Board Medics after you receive the module. We do not require an up front core deposit, but a core charge must be captured if a rebuildable turbo actuator is not returned to Circuit Board Medics. If your core is not received within 15 calendar days, an additional core charge of $350 will be charged to your credit card.


Your original turbo actuator must meet the following qualifications:

  • No fire damage
  • No prior repair attempts
  • No damage to the housing
  • Must be a genuine Holset actuator

Does your actuator have a coolant port on the side?

Threaded Coolant Port

Smooth Coolant Port
