The Chelsea 871XGFJP-D5RS is a 10-bolt PowerShift (hydraulic) PTO assembly engineered for Allison transmissions. Part of Chelsea's 871 Series, this unit carries a continuous torque rating of up to 670 lb-ft (908 N-m) with no derating required for continuous duty. Nine speed ratios and thirteen output options give installers the flexibility to match a wide range of driven equipment. The compact housing profile reduces clearance conflicts during installation. Standard features include a ductile iron bearing cap rated 117% stronger than gray iron, an O-ring sealing configuration between the housing and bearing cap to improve clamp load and resist vibration, and Wet Spline pump flange lubrication to extend both PTO and pump shaft service life. Optional Quiet Gear input, SmartStart shock-load reduction, and Electronic Overspeed Control (EOC) are also available within the series. Call us to confirm the exact configuration is correct for your application.
The 871 Series replaces the popular Chelsea 870 Series PTO. Common markets include fire and rescue apparatus, truck cranes, pumper-cleaner units, and refuse vehicles. The 871 Series is the only Chelsea PTO to offer all three of the brand's premium options - Wet Spline, SmartStart, and Quiet Gear - on a single platform.
