The Chelsea 871 Series Power Take-Off, part number 871XAFJW-L3RZ or 871XAFJWL3RZ, is a compact 10-bolt hydraulic PowerShift PTO designed for Allison transmission applications. The series is rated for continuous-duty operation at torque capacity up to 670 lb-ft (908 N-m), so no derating is required for sustained-run equipment such as fire and rescue apparatus, pumper cleaners, refuse trucks, and truck cranes. Nine available speed ratios and thirteen output options give installers flexibility to match drive and pump 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 vibration damage. Optional Wet Spline, SmartStart, and Quiet Gear configurations are available within the 871 Series. The 871XAFJW-L3RZ is sold by Pro Gear and Transmission.
