Shift type is wire/cable mechanical. The output shaft is a 1-1/4" round with keyway. Intermittent torque is rated at 250 lb-ft (339 Nm); check application pages for the torque rating specific to your installation. Output power runs 46-55 HP (31-40 kW), with shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Compatible transmissions include Allison, Eaton/Fuller, Volvo/Mack, Hino, and others. The cast iron housing uses tapered cone output bearings for strong load capacity, and pump shafts are greaseable to reduce spline fretting and corrosion.
