Description
The Chelsea 871 Series Power Take-Off, part number 871XGFJP-G5XV or 871XGFJPG5XV, is a 10-bolt PowerShift (hydraulic) PTO 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 installers wide flexibility across fire and rescue, refuse, truck crane, and pumper cleaner applications. A ductile iron bearing cap rated 117% stronger than gray iron and an O-ring sealing configuration between the housing and bearing cap address vibrational loads from modern engine designs. The compact housing minimizes clearance issues, and the Wet Spline pump flange helps extend PTO and pump shaft service life. Call us to confirm proper fit for your specific transmission and application.
