The Chelsea 890 Series Power Take-Off, part number 890CBFJW-B3CS or 890CBFJWB3CS, is a hydraulic PowerShift (hot-shift) PTO 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 continuous torque up to 670 lb-ft and intermittent torque rated at 501+ lb-ft. Shaft power output reaches 64 HP at 500 RPM and 128 HP at 1,000 RPM. The one-piece main shaft eliminates input splines between the PTO and the output extension, and the clutch is positioned at the rear of the housing so the gear section tucks tightly against the transmission, improving pump clearance. Wet-spline output technology protects both the PTO and pump shaft in demanding duty cycles. Fits aerial, fire and rescue, refuse, and truck crane applications. Call us to confirm proper fit for your application.
