The Chelsea 871 Series Power Take-Off Assembly, part number 871XAFJW-D3RY or 871XAFJWD3RY, is a 10-bolt PowerShift (hydraulic) PTO engineered for Allison transmission applications. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous duty. Nine speed ratios and thirteen output options cover a wide range of vocational requirements. A ductile iron bearing cap rated 117% stronger than gray iron and an O-ring sealing configuration between the housing and bearing cap improve clamp load and reduce vibration-related wear. The 871 Series is the only Chelsea PTO to combine Wet Spline, SmartStart, and Quiet Gear options in a single platform. Call us to confirm proper fit for your application.
