About This Remanufactured BorgWarner B3G Turbocharger — Detroit Diesel DD15 The BorgWarner B3G turbocharger is the factory unit on the Detroit Diesel DD15 engine from 2015 through 2021, powering Freightliner Cascadia and other premium Class 8 trucks in long-haul service. The DD15 is known for its efficiency and power density, and the B3G turbocharger — a variable geometry unit with electronic actuator control — is integral to both performance and the engine management system. Part number A4720901480 is the factory OEM designation for this unit. B3G failures are often flagged by the DD15 engine management system as boost control faults before any visible symptoms appear. Physical failure modes include bearing wear causing noise or shaft play, VGT actuator errors (actuator position out of range), and seal failure causing oil in the intake. What Is Rebuilt Full teardown, cleaning, and inspection of all components New journal bearings, thrust bearing, and seals throughout VGT nozzle ring and actuation mechanism inspection Electronic actuator tested for proper range and response CHRA dynamically balanced before final assembly PT Turbo — Detroit Diesel Turbo Specialists PT Turbo has been rebuilding Detroit Diesel turbochargers since 1978 in San Bernardino, California.
