The Chelsea 890 Series Power Take-Off, part number 890LDFJW-G5XY or 890LDFJWG5XY, is a hydraulic hot-shift PTO engineered specifically for Allison 3000 MD and 4000 HD Series transmissions. It uses a 10-bolt mounting pattern and an SAE C output flange, with a wet-spline output shaft to reduce wear on the PTO and pump shaft in demanding service. The one-piece main shaft eliminates the input splines found in PTO-plus-extension setups, and the rear-mounted clutch lets the housing tuck tightly against the transmission for improved pump clearance. Shaft power output reaches 64 HP at 500 RPM and 128 HP at 1,000 RPM, with a continuous torque rating up to 670 ft-lb. Common applications include aerial trucks, fire and rescue, refuse vehicles, and truck cranes. A genuine Chelsea part available from Pro Gear and Transmission.
