The Chelsea 871XGFJW-G5RS is a 10-bolt PowerShift (hydraulic) Power Take-Off from Chelsea's 871 Series, designed for Allison transmission applications. 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 installers broad flexibility across fire and rescue, truck crane, pumper cleaner, and refuse applications. The compact housing keeps clearance issues to a minimum. A ductile iron bearing cap - 117% stronger than gray iron - and an O-ring sealing configuration between the housing and bearing cap improve clamp load and reduce vibrational stress. This assembly also supports Chelsea's Wet Spline, SmartStart, and Quiet Gear options within the same platform. Also referenced as 871XGFJWG5RS. Call us to confirm proper fit for your application.
