871XAFJP-B3RZ Chelsea PTO Assembly

The Chelsea 871 Series Power Take-Off Assembly, part number 871XAFJP-B3RZ or 871XAFJPB3RZ, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmissions. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 N-m) with no derating required for continuous duty applications. Nine speed ratios and thirteen output options give this unit broad application flexibility across fire and rescue, refuse, pumper/cleaner, and truck crane installations. A ductile iron bearing cap rated 117% stronger than gray iron, combined with an O-ring sealing configuration between the housing and bearing cap, reduces vibrational stress from modern engine designs. The compact housing profile keeps clearance conflicts to a minimum. Optional Wet Spline, SmartStart, and Quiet Gear configurations are available. Chelsea's 871 Series is sold by Pro Gear and Transmission. Call us to confirm the right configuration for your specific installation.
