The Chelsea 871 Series Power Take-Off (part number 871XEFJW-D3RS or 871XEFJWD3RS) is a compact 10-bolt PowerShift hydraulic PTO designed for Allison transmissions. The 871 Series delivers continuous-duty torque capacity up to 670 lb-ft (908 N-m) without derating, backed by nine available speed ratios and thirteen output configurations. A ductile iron bearing cap provides 117% greater strength compared to gray iron, and an O-ring sealing configuration between the housing and bearing cap improves clamp load while reducing vibration-related stress. Optional Wet Spline pump flange, SmartStart, and Quiet Gear input round out the available configurations. Common applications include fire and rescue apparatus, pumper-cleaner trucks, refuse vehicles, and truck cranes. Call us to confirm proper fit for your application.
The 871 Series replaces the earlier Chelsea 870 Series PTO. This assembly is the only Chelsea PTO to offer all three of the manufacturer's high-demand options in a single platform: Wet Spline pump flange, SmartStart, and Quiet Gear. Typical market applications include fire and rescue, pumper-cleaner, refuse, and truck crane installations. Reference documents: 871 Series Parts List (HY25-2871-M1/US) and the 267/281/288/871/878 Series Owner's Manual are published by Parker Chelsea for this series.
