The Chelsea 871 Series Power Take-Off (part number 871XEFJP-B3RK or 871XEFJPB3RK) is a 10-bolt, hydraulically shifted (PowerShift) PTO designed for Allison transmissions. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous duty, making it well suited for demanding vocational applications including fire and rescue, refuse, pumper cleaner, and truck crane service. Nine speed ratios and thirteen output options give installers broad flexibility. The ductile iron bearing cap is 117% stronger than the gray iron cap used on predecessor designs, and an O-ring sealing configuration between the housing and bearing cap reduces vibrational effects and improves clamp load. The 871 Series replaces the Chelsea 870 Series PTO. Call us to confirm proper fit for your application.
