The Chelsea 871XCFJW-B5RS or 871XCFJWB5RS is a 10-bolt PowerShift (hydraulic) 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) without derating, making it a practical choice for fire and rescue, refuse, truck crane, and pumper-cleaner applications. Nine speed ratios and thirteen output options give installers a wide fit window. The ductile iron bearing cap is 117% stronger than the gray iron cap used in the predecessor 870 Series, and an o-ring sealing configuration between the housing and bearing cap improves clamp load and resists vibrational stress. Optional Quiet Gear input, SmartStart shock-load reduction, and Electronic Overspeed Control (EOC) are available within the series. Call us to confirm the exact configuration for your application.
