The Chelsea 897 Series Power Take-Off 897LEFJW-M5AF or 897LEFJWM5AF is a constant-mesh PTO designed specifically for Allison 3000 and 4000 Series transmissions. It mounts via a 10-bolt pattern and uses an SAE C outlet flange with an SAE C (XS) output shaft. The continuous-duty torque rating reaches 670 lb-ft (908 Nm), with intermittent torque capability above 501 lb-ft. Shaft power output is 64 HP at 500 RPM and 128 HP at 1,000 RPM. The one-piece main shaft eliminates the input splines found in PTO-plus-extension configurations, and the pump interface locates to the rear of the transmission for improved frame-rail clearance. Wet spline output lubrication extends pump shaft life in demanding service. Common applications include aerial trucks, fire and rescue, refuse, and truck crane equipment. Call us to confirm proper fit for your application.
