If you’ve just purchased a Rotomaster remanufactured turbocharger, your unit comes with an upgraded Compact Brushless Actuator (CBA). This replaces the older Smart Remote Actuator (SRA), which is no longer available for Ford 6.4L Powerstroke V2S and HP Turbo systems from 2008-2010.
The CBA delivers the same performance as the original but comes with significant advantages, making installation easier and improving durability.
Why Upgrade to the CBA Actuator?
The CBA is a modernized replacement for the discontinued SRA, offering these key benefits:
- Newer, more compact design
- Higher torque capability for better response
- No water cooling required, simplifying installation
- Higher temperature tolerance for improved durability
Step-by-Step Installation Guide
Step 1: Remove Coolant Pipe Routing
One of the biggest advantages of the CBA is that it doesn’t require water cooling like the old SRA. This means you need to reroute your existing coolant lines.
Action Step:
- Remove the actuator coolant block.
- Remove the short hose that connected the old actuator coolant block to the reservoir.
- Ensure the cooling circuit is properly closed without modifications.
Step 2: Calibrate the New Actuator
Unlike the older SRA, the CBA automatically calibrates when powered on—no external calibration is required.
Action Step:
- Turn on the vehicle to power up the actuator.
- Rev the engine to 20% of full travel (a safe position).
- The actuator will wait for the ECU to send information before executing a full-span sweep to learn its limits.
