The Chelsea 890LEFJW-B5ZS or 890LEFJWB5ZS is a hydraulic hot-shift Power Take-Off built for Allison 3000 MD and 4000 HD Series transmissions. The 890 Series mounts using a 10-bolt pattern and positions the SAE C output flange at the rear of the transmission, creating clearance between the PTO and the frame rail without the need for a separate extension. The main shaft is a one-piece design, eliminating the input splines that would otherwise sit between the PTO body and the output extension. The clutch locates at the rear of the housing so the gear section tucks tight against the transmission. Wet Spline lubrication protects the PTO and pump shaft splines under continuous-duty demands. Continuous torque rating reaches 670 lb-ft; intermittent torque is rated at 501 lb-ft and above. Shaft power at 1,000 RPM is 128 HP. Call us to confirm proper fit for your application.
