The Chelsea 871LDFJW-B5TK or 871LDFJWB5TK is a 10-bolt hydraulic PowerShift Power Take-Off from the Chelsea 871 Series, designed for Allison transmissions. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous-duty applications. Nine speed ratios and thirteen output options give this unit broad versatility across fire and rescue, refuse, truck crane, and pumper-cleaner applications. The ductile iron bearing cap is 117% stronger than gray iron, and the O-ring sealing configuration between the housing and bearing cap improves clamp load while reducing the vibrational effects of modern engine designs. Wet Spline, SmartStart, and Quiet Gear options are all available within the 871 Series. Call us to confirm proper fit for your application.
