The Chelsea 890REFJW-B5XK or 890REFJWB5XK is a hydraulic PowerShift Power Take-Off from the Chelsea 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 shaft with an SAE C outlet flange. 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 PTO housing so the gear section tucks close to the transmission for improved frame-rail clearance. Wet-spline lubrication is built in to extend pump shaft life under continuous-duty demand. Shaft power output reaches 64 HP at 500 RPM and 128 HP at 1,000 RPM. Genuine Chelsea from Pro Gear and Transmission. Call us to confirm proper fit for your application.
