The Chelsea 890LEFJW-D5AF or 890LEFJWD5AF is a hydraulic PowerShift PTO from the 890 Series, designed specifically for Allison 3000 MD and 4000 HD Series transmissions. It mounts with a 10-bolt pattern and delivers up to 670 ft-lb continuous-duty torque with an SAE C ("XS") output shaft and SAE C outlet flange. The one-piece main shaft eliminates input splines between the PTO and output extension, and the clutch locates at the rear of the housing to tuck tightly against the transmission and improve pump clearance. Wet spline lubrication is standard, extending PTO and pump shaft service life in demanding applications such as aerial, fire and rescue, refuse, and truck crane work. Shaft power output is 64 HP at 500 RPM and 128 HP at 1,000 RPM. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
