The Chelsea 890CEFJW-B3ZS or 890CEFJWB3ZS is a hydraulic PowerShift power take-off built 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, moving the pump away from the frame rail for improved clearance. The one-piece main shaft eliminates input splines between the PTO and the output extension, and the wet-spline output extends pump shaft life under demanding duty cycles. Continuous torque is rated up to 670 ft-lb, with intermittent torque starting at 501 ft-lb. Shaft power output reaches 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.
