The Chelsea 871 Series Power Take-Off, part number 871XGFJP-B5SV or 871XGFJPB5SV, is a 10-bolt hydraulic PowerShift 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 operation. Nine available speed ratios and thirteen output configurations give installers broad flexibility across fire and rescue, refuse, pumper cleaner, and truck crane applications. A ductile iron bearing cap rated 117% stronger than gray iron and an O-ring sealing configuration between the housing and bearing cap reduce vibration damage from modern engine designs. Optional Wet Spline pump flange, SmartStart shock-load reduction, Quiet Gear input, and Electronic Overspeed Control (EOC) make the 871 Series the only Chelsea PTO to offer all three of the brand's high-demand protection solutions. Call us to confirm the correct configuration for your truck and pump combination.
The 871 Series replaces the earlier Chelsea 870 Series PTO. All design upgrades - ductile iron bearing cap, O-ring housing seal, and optional Wet Spline, SmartStart, and Quiet Gear - are focused on reducing the vibrational damage caused by current and future engine designs. Applicable Parker Chelsea documentation includes the 267/281/288/871/878 Series Owner's Manual and the 871 Series Parts List (HY25-2871-M1/US). Part number 871XGFJP-B5SV is also referenced as SP871XGFJP-B5SV in some catalog listings. Pro Gear and Transmission carries this genuine Chelsea PTO - call us to confirm proper fit and configuration for your specific vehicle and driven equipment.
