The Chelsea 871 Series Power Take-Off, part number 871XAFJP-D5RF or 871XAFJPD5RF, is a 10-bolt PowerShift (hydraulic-shift) PTO designed for Allison transmissions. The 871 Series carries a continuous torque rating up to 670 lb-ft (908 N-m) with no derating required for continuous-duty operation. Nine speed ratios cover a wide range of output requirements, and thirteen output configurations are available across the series. A ductile iron bearing cap delivers 117% greater strength than gray iron, while an O-ring sealing configuration between the housing and bearing cap improves clamp load and reduces the vibrational effects of modern engine designs. The compact housing minimizes clearance concerns during installation. Optional Wet Spline, SmartStart, and Quiet Gear features make the 871 the only Chelsea PTO offering all three solutions in one unit. Call us to confirm the correct configuration for your application.
