The Chelsea 890LFFJW-D5XS or 890LFFJWD5XS is a hydraulic PowerShift power take-off from the Chelsea 890 Series, engineered specifically for Allison 3000 MD and 4000 HD Series transmissions. It mounts via a 10-bolt pattern and locates the pump output to the rear of the transmission, tucking the housing and gear section tightly against the trans for improved clearance between the pump and frame rail. The output shaft is SAE C configuration with Wet Spline lubrication to extend both PTO and pump shaft life under demanding duty cycles. Continuous-duty torque for the 890 Series reaches up to 670 lb-ft, with intermittent torque ratings above 501 lb-ft. Shaft power at 1,000 RPM is 128 HP. The one-piece main shaft eliminates input splines between the PTO body and the output extension. A genuine Chelsea part available from Pro Gear and Transmission.
