The Chelsea 890LFFJW-D5XY or 890LFFJWD5XY is a hydraulic PowerShift PTO assembly built for Allison 3000 MD and 4000 HD Series transmissions. It mounts via a 10-bolt pattern and positions the SAE C flange output at the rear of the transmission, tucking the housing tightly inboard so the gear section clears the frame rail while moving the pump further back for added clearance. The one-piece main shaft eliminates input splines between the PTO body and the output extension. Wet-spline output technology reduces spline wear under continuous-duty loads. The 890 Series delivers up to 670 ft-lb continuous torque and shaft power of 64 HP at 500 RPM or 128 HP at 1,000 RPM. A genuine Chelsea part from Pro Gear and Transmission.
