The Chelsea 871 Series Power Take-Off, part number 871XGFJP-D5XV or 871XGFJPD5XV, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmissions. The compact housing reduces clearance issues across multiple installation arrangements. Continuous torque capacity reaches 670 lb-ft (908 N-m), with no derating required for continuous-duty operation. Nine speed ratios cover a wide range of application speeds, and thirteen output options accommodate various hydraulic pump configurations. A ductile iron bearing cap delivers 117% greater strength than gray iron, and the o-ring sealing configuration between the housing and bearing cap reduces vibrational effects while improving clamp load. The 871 Series is the only Chelsea PTO offering all three premium options -- Wet Spline, SmartStart, and Quiet Gear -- in a single platform. Call us to confirm proper fit for your specific transmission and equipment.
