Eaton expands its aftermarket drivetrain portfolio with five new flywheel part numbers covering Volvo, Paccar, Detroit Diesel and Caterpillar engine applications commonly used in medium- and heavy-duty fleets. The additions include coverage for Volvo VED12, Paccar MX13, Detroit Diesel DD15 (AMT and MT variants), and Caterpillar 3306 platforms, with cross-reference part numbers to support easier substitution in service environments. The expanded lineup is intended to improve parts availability for high-volume engine platforms, helping fleets and repair shops reduce downtime during drivetrain repairs. The flywheels support torque transfer and smooth power delivery, addressing ongoing demand for replacement components as fleets extend vehicle service life.
