The Chelsea 871 Series Power Take-Off Assembly, part number 871XGFJP-D5AC or 871XGFJPD5AC, is a 10-bolt PowerShift (hydraulic shift) PTO designed for Allison transmissions. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 N-m) with no derating required for continuous-duty operation. Nine speed ratios and thirteen output options give technicians the flexibility to match the PTO to a wide range of equipment, from fire and rescue apparatus to refuse trucks and truck cranes. 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 effects while improving 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.
