The Chelsea 871 Series Power Take-Off, part number 871XAFJP-D3AC or 871XAFJPD3AC, is a 10-bolt hydraulic PowerShift 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 operation. Nine speed ratios and thirteen output configurations give technicians flexibility to match a wide range of driven equipment. 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 demands of modern engine designs. Optional Wet Spline pump flange, SmartStart, and Quiet Gear input round out the feature set. Call us to confirm proper fit for your application.
The 871 Series replaces the Chelsea 870 Series PTO. It is the only Chelsea PTO to offer all three of Chelsea's high-demand options on a single platform: Wet Spline, SmartStart, and Quiet Gear. Relevant service documents include the 267/281/288/871/878 Series Owner's Manual, the 871 Series Parts List (HY25-2871-M1/US), and the 871 Series Sales Literature published by Parker Chelsea.
