The Chelsea 871 Series Power Take-Off, part number 871XEFJP-D5RS or 871XEFJPD5RS, is a 10-bolt, PowerShift (hydraulic) 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 applications. Nine speed ratios and thirteen output options give installers wide flexibility across fire and rescue, truck crane, pumper cleaner, and refuse applications. A ductile iron bearing cap rated 117% stronger than gray iron, combined with an o-ring sealing configuration between the housing and bearing cap, addresses the vibrational stress of modern engine designs. The compact housing profile reduces clearance conflicts during installation. Call us to confirm proper fit for your specific transmission and application.
