The Chelsea 871LGFJW-D5TS is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmissions. The 871 Series features a compact housing that reduces clearance issues, a ductile iron bearing cap rated 117% stronger than gray iron, and an o-ring sealing configuration between the housing and bearing cap to improve clamp load and reduce the effects of engine vibration. Continuous torque capacity for the series reaches 670 lb-ft (908 Nm), with no derating required for continuous-duty operation. The 871 Series supports nine speed ratios and thirteen output options, and is the only Chelsea PTO offering Wet Spline, SmartStart, and Quiet Gear options together. Sold by Pro Gear and Transmission.
