The Chelsea 897 Series Power Take-Off Assembly, part number 897CAFJW-M3ZS or 897CAFJWM3ZS, is a constant-mesh PTO built for Allison 3000 and 4000 Series transmissions. It mounts via a 10-bolt pattern and positions the SAE C output flange at the rear of the transmission, tucking the housing tightly inboard for improved clearance between the pump and the frame rail. A one-piece main shaft eliminates the input splines found in conventional PTO-plus-extension setups. Wet Spline Technology lubricates the output interface to reduce wear in high-cycle or demanding duty. Continuous torque capacity reaches 670 ft-lb; intermittent torque is rated at 501+ ft-lb. Output power at 1,000 RPM reaches 128 HP. Common applications include aerial trucks, fire and rescue, refuse, and truck cranes. Call us to confirm proper fit for your specific Allison transmission configuration.
