The Chelsea 871LDFJW-B5TZ or 871LDFJWB5TZ is a 10-bolt PowerShift (hydraulic) Power Take-Off from Chelsea's 871 Series, engineered for Allison transmission applications. The series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous-duty operation. A ductile iron bearing cap rated 117% stronger than gray iron handles the vibrational stress common with modern engine designs, and an O-ring sealing configuration between the housing and bearing cap improves clamp load and sealing reliability. Nine gear ratios and thirteen output options give this PTO broad application flexibility across fire and rescue, refuse, truck crane, and pumper-cleaner equipment. Optional Wet Spline, SmartStart, and Quiet Gear configurations are available within the 871 Series. The 871 Series replaces the Chelsea 870 Series. Call us to confirm the right configuration for your application.
