The Chelsea 890CCFJW-B3XY or 890CCFJWB3XY is a hydraulic PowerShift PTO from the Chelsea 890 Series, designed specifically for Allison 3000 MD and 4000 HD Series transmissions. It mounts via a 10-bolt pattern and delivers an SAE C ("XS") output flange, with continuous-duty torque rated up to 670 ft-lbs and intermittent torque exceeding 501 ft-lbs. Shaft power output reaches 64 HP at 500 RPM and 128 HP at 1,000 RPM. The 890 Series moves the PTO pump mounting flange to the rear of the transmission for improved pump clearance, and the wet-spline output (W designation) extends pump and PTO shaft life in demanding service. The one-piece main shaft eliminates input splines between the PTO and output extension, and a rear-mounted clutch allows the housing to tuck tightly against the transmission. Typical applications include aerial trucks, fire and rescue, refuse trucks, and truck cranes. Call us to confirm proper fit for your specific transmission configuration.
