The Chelsea 871LAQTW-B5TK or 871LAQTWB5TK is a 10-bolt, hydraulic PowerShift Power Take-Off from the 871 Series, designed for Allison transmissions. The 871 Series delivers continuous-duty torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous operation. Nine speed ratios and thirteen output options give this series broad application flexibility across fire and rescue, refuse, truck crane, and pumper-cleaner equipment. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap improves clamp load while reducing vibrational effects. Wet Spline lubrication, SmartStart, and Quiet Gear options are available. Call us to confirm proper fit for your application.
