The Chelsea 871 Series Power Take-Off Assembly, part number 871XJFJP-G5XV or 871XJFJPG5XV, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmissions. Continuous torque capacity reaches 670 lb-ft (908 N-m) with no derating required for continuous duty applications. Nine speed ratios and thirteen output options give installers broad flexibility across fire and rescue, truck crane, pumper cleaner, and refuse applications. The ductile iron bearing cap is 117% stronger than gray iron, and the o-ring sealing configuration between housing and bearing cap improves clamp load while reducing vibrational effects. Optional Wet Spline pump flange, SmartStart shock-load reduction, Quiet Gear input, and Electronic Overspeed Control (EOC) are available within the 871 Series. The compact housing profile reduces clearance conflicts at installation. Call us to confirm the correct configuration for your application.
