The Chelsea 871 Series Power Take-Off, part number 871XJFJP-D5SV or 871XJFJPD5SV, 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 options give installers the flexibility to match a wide range of hydraulic pump and driveline configurations. The compact housing reduces clearance issues common in tight chassis installations. This series supports Wet Spline lubrication, SmartStart shock-load reduction, and Quiet Gear input as available options. 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 effects. Common markets include fire and rescue, refuse, truck cranes, and pumper-cleaner applications. Call us to confirm proper fit for your application.
The Chelsea 871 Series replaces the earlier 870 Series PTO. The 871 Series is the only Chelsea PTO to offer all three of Chelsea's high-demand solutions - Wet Spline, SmartStart, and Quiet Gear - on a single platform. Electronic Overspeed Control (EOC) is available to protect driven equipment. Typical market applications include fire and rescue apparatus, refuse trucks, truck cranes, and pumper-cleaner vehicles. Part number 871XJFJP-D5SV is also referenced as SP871XJFJP-D5SV in some catalog sources.
