The Chelsea 890PAFJW-D5XY or 890PAFJWD5XY is a hydraulic hot-shift power take-off from the 890 Series, engineered specifically for Allison 3000 MD and 4000 HD Series transmissions. It mounts via a 10-bolt pattern and positions the pump output to the rear of the transmission, improving clearance between the PTO and the frame rail. The one-piece main shaft eliminates input splines between the PTO body and the output extension, and the clutch is located at the rear of the housing so the gear section sits tight against the transmission. The SAE C ("XS") output uses wet-spline technology to reduce wear on the pump shaft in demanding duty cycles. Continuous torque is rated up to 670 lb-ft; shaft power reaches 128 HP at 1,000 RPM.
