The Chelsea 871LEFJW-B5TS or 871LEFJWB5TS is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 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 need to derate for continuous operation. Nine speed ratios and thirteen output options give installers broad flexibility across fire and rescue, truck crane, pumper cleaner, and refuse body applications. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap reduces vibrational effects and improves clamp load. Optional Wet Spline pump flange, SmartStart, and Quiet Gear input round out the available configurations. A genuine Chelsea part, sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
The Chelsea 871 Series replaces the earlier 870 Series PTO, incorporating upgraded materials and sealing across the product line. Applicable Parker documentation includes the 267/281/288/871/878 Series Owner's Manual, the 871 Series Parts List (HY25-2871-M1/US), and the 871 Series Sales Literature. The 871 Series is the only Chelsea PTO to offer all three of Chelsea's premium options, Wet Spline, SmartStart, and Quiet Gear, within a single platform. Common application markets include fire and rescue apparatus, truck cranes, pumper cleaner bodies, and refuse vehicles.
