Mercedes-Benz transmissions available on Sterling Acterra models
Mercedes-Benz manual transmissions are now available for order on Sterling Acterra class 5-8 trucks.
The six-speed Mercedes-Benz manual transmissions feature hydraulically-actuated clutch systems and are offered in two versions — the direct-drive MBT520 for trucks up to 40,000 pounds gross combination weight and the over-drive MBT660 for trucks up to 60,000 pounds GCW. The transmissions are available for the class 5-8 Sterling Acterra models working in beverage hauling, towing, pick-up and delivery, utility service, construction, and other applications.
The MBT520 is a direct-drive transmission with an overall gear ratio of 9.20, for engines that produce peak torque up to 520 pound-feet. The MBT660 is an overdrive transmission for engines up to 660 pound-feet peak torque, with an overall gear ratio of 9.18.
Both feature a standard SAE 6-bolt PTO port on their right side for easy installation of a power take-off device. The port is mounted at the 5 o’clock position.
The MBT520 and MBT660 are compatible with medium-duty diesel engines built by Mercedes-Benz, Caterpillar and Cummins and carry a two-year warranty.
