The Chelsea 871 Series Power Take-Off, part number 871XEFJR-N5XV or 871XEFJRN5XV, is a 10-bolt PowerShift (hydraulic-shift) PTO designed for Allison transmissions. The 871 Series carries a continuous torque rating 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 broad flexibility across fire and rescue, refuse, pumper/cleaner, and crane truck applications. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap reduces vibrational stress and improves clamp load. Optional Wet Spline pump flange, SmartStart, and Quiet Gear input round out the feature set. Call us to confirm proper fit for your application.
