It uses a lever mechanical shift and delivers up to 500 lb-ft intermittent torque, with shaft power rated at 48 HP at 500 RPM and 95 HP at 1,000 RPM. The output shaft is a 1-1/2"-10T spline with a 1410 companion flange. Compatible transmission manufacturers include Volvo/Mack, Allison, and Eaton/Fuller. The removable shift cover simplifies backlash adjustment, and the cast iron housing is engineered for demanding service in applications such as fire trucks, bulk haulers, oil field equipment, and large recovery vehicles.
