The Chelsea 871 Series Power Take-Off Assembly, part number 871XEFJP-D3AC or 871XEFJPD3AC, 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 you the flexibility to match a wide range of equipment requirements. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap improves clamp load while reducing the vibrational effects of modern engine designs. Optional Wet Spline pump flange, SmartStart, and Quiet Gear features make this the only Chelsea PTO offering all three. Call us to confirm proper fit for your application.
