Shift engagement is wire/cable mechanical. The 1-1/4" round output shaft with keyway delivers up to 250 lb-ft intermittent torque (339 Nm); verify your specific rating on the Chelsea application pages. Shaft power output is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Compatible transmission manufacturers include Allison, Eaton/Fuller, Volvo/Mack, and Hino, among others. The cast iron housing uses tapered cone output bearings for load capacity, and greaseable pump shafts help reduce spline fretting and corrosion.
