The Chelsea 890LCFJW-B5AF or 890LCFJWB5AF is a hydraulic PowerShift (hot-shift) power take-off built for Allison 3000 MD and 4000 HD Series transmissions. It mounts via a 10-bolt pattern and positions the pump output to the rear of the transmission, tucking between the gearbox and the frame rail to maximize pump clearance without an extension adapter. The main shaft is a one-piece design that eliminates the input splines between the PTO and the output extension. Output is an SAE C (XS) flange with Wet Spline technology to reduce pump shaft wear in demanding duty cycles. Continuous-duty torque reaches 670 lb-ft; intermittent torque is rated at 501+ lb-ft. Shaft power runs 64 HP at 500 RPM and 128 HP at 1,000 RPM. Common platforms include aerial, fire and rescue, refuse, and crane trucks. Call us to confirm proper fit for your specific transmission configuration.
