The Chelsea 871 Series Power Take-Off, part number 871XJFJP-D5BC or 871XJFJPD5BC, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmissions. The series carries a continuous torque rating up to 670 lb-ft (908 N-m), and the compact housing profile is engineered specifically to reduce clearance conflicts during installation. A ductile iron bearing cap delivers 117% greater strength compared to gray iron, while an O-ring sealing configuration between the housing and bearing cap improves clamp load and resists the vibrational loads generated by modern engine designs. Nine speed ratios and thirteen output options give this unit broad application flexibility across fire and rescue, refuse, pumper/cleaner, and truck crane equipment. Electronic Overspeed Control (EOC) is available to protect driven equipment. Call us to confirm proper fit for your application.
