The Chelsea 871XHFJP-B5XV is a 10-bolt PowerShift (hydraulic) 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. Its compact housing keeps clearance issues to a minimum, and the ductile iron bearing cap is 117% stronger than the gray iron cap used in its predecessor, the 870 Series. An o-ring sealing configuration between the housing and bearing cap improves clamp load and reduces the effects of engine vibration. The 871 Series offers nine speed ratios and thirteen output options, including SAE B, SAE BB, and SAE C pump spline configurations, making it a versatile fit across fire and rescue, refuse, truck crane, and pumper cleaner applications. Available with Wet Spline, SmartStart, and Quiet Gear options.
