The Chelsea 890XCFJW-D5XY or 890XCFJWD5XY 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 positions the SAE C output flange to the rear of the transmission, improving pump clearance without the need for a separate extension. The main shaft is one piece, eliminating the input splines between the PTO body and the output. A wet-spline output extends pump shaft life under demanding duty cycles. Continuous torque reaches 670 ft-lb, with intermittent torque rated at 501+ ft-lb. Shaft power output is 64 HP at 500 RPM and 128 HP at 1,000 RPM. Common applications include aerial trucks, fire and rescue, refuse trucks, and truck cranes. A genuine Chelsea part available from Pro Gear and Transmission.
