The Chelsea 871LFFJW-B5TK is a 10-bolt, PowerShift (hydraulic) Power Take-Off from Chelsea's 871 Series, designed for Allison transmission applications. The 871 Series carries a continuous torque rating up to 670 lb-ft (908 N-m) with no derating required for continuous duty cycles. Nine available speed ratios and thirteen output options give this series broad application flexibility across fire and rescue, refuse, truck crane, and pumper/cleaner equipment. This unit is the only Chelsea PTO series to combine all three of Chelsea's high-demand options: Wet Spline pump flange for extended shaft life, SmartStart for reduced shock load at startup, and Quiet Gear input. The ductile iron bearing cap and o-ring sealing configuration replace the legacy 870 Series with measurably stronger, more vibration-resistant construction. Call us to confirm proper fit for your specific transmission and application. Part number 871LFFJW-B5TK or 871LFFJWB5TK.
The 871 Series replaces the Chelsea 870 Series PTO. This is the only Chelsea PTO series to offer Wet Spline, SmartStart, and Quiet Gear options in a single platform.
