The Chelsea 871 Series Power Take-Off, part number 871XAFJP-H5RS or 871XAFJPH5RS, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmissions. The 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 options give technicians a wide range of configuration possibilities for demanding vocational applications including fire and rescue, refuse, truck cranes, and pumper-cleaner units. A ductile iron bearing cap rates 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap improves clamp load while reducing vibrational effects. The compact housing height limits clearance conflicts during installation. Call us to confirm proper fit for your specific transmission and application.
The 871 Series replaces the Chelsea 870 Series PTO. This series is the only Chelsea PTO offering all three of Chelsea's high-demand options in a single platform: Wet Spline (extends PTO and pump shaft life), SmartStart (reduces shock load at start-up), and Quiet Gear input. Electronic Overspeed Control (EOC) is also available to protect driven equipment. Typical markets include fire and rescue, refuse, truck cranes, and pumper-cleaner bodies. Reference documents for this series include the 871 Series Parts List (HY25-2871-M1/US) and the 267/281/288/871/878 Series Owner's Manual published by Parker Chelsea.
