The Chelsea 871LDQTW-B3TS or 871LDQTWB3TS is a 10-bolt PowerShift (hydraulic) PTO Assembly from the 871 Series, designed for Allison transmissions. The 871 Series supports continuous torque up to 670 lb-ft (908 N-m) with no derating required for continuous duty. Nine speed ratios and thirteen output options give this series exceptional application flexibility for fire and rescue, truck cranes, refuse, and pumper/cleaner equipment. A ductile iron bearing cap rated 117% stronger than gray iron, combined with an O-ring sealing configuration between the housing and bearing cap, addresses vibration from modern engine designs. Wet Spline lubrication, SmartStart, and Quiet Gear options are all available on this series. Call us to confirm the correct fit for your specific transmission and application.
