The Chelsea 897 Series Power Take-Off Assembly, part number 897LEFJW-M5XV or 897LEFJWM5XV, is a constant-engagement PTO engineered for Allison 3000 and 4000 Series transmissions. The 897 Series uses a one-piece main shaft that eliminates the input splines found between a standard PTO and an output extension, positioning the pump interface at the rear of the transmission so the housing and gear section tuck tightly against the transmission for better clearance. Mounting is 10-bolt, with an SAE C outlet flange and wet-spline output technology to reduce wear on the PTO and pump shaft under demanding duty cycles. Continuous torque rating reaches 670 ft-lb; shaft power output runs 64 HP at 500 RPM and 128 HP at 1,000 RPM. Typical applications include aerial trucks, fire and rescue, refuse, and truck crane service. Call us to confirm proper fit for your specific Allison transmission configuration.
