The Chelsea 890CBFJW-B3CK or 890CBFJWB3CK is a hydraulic PowerShift PTO Assembly from the 890 Series, engineered specifically for Allison 3000 MD and 4000 HD Series transmissions. It mounts via a 10-bolt pattern and uses an SAE C ("XS") output flange, delivering a continuous-duty torque rating of 670 ft-lb and intermittent torque above 501 ft-lb. Output power reaches 128 HP at 1,000 RPM and 64 HP at 500 RPM. The one-piece main shaft eliminates input splines between the PTO and output extension, and the clutch sits at the rear of the housing to improve clearance between the transmission and frame rail. Wet-spline output technology helps extend shaft life in demanding duty cycles. Typical applications include aerial trucks, fire and rescue apparatus, refuse trucks, and truck cranes. Call us to confirm proper fit for your application.
