The Chelsea 871XJQTP-B3XV is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmissions. The 871 Series delivers continuous torque ratings up to 670 lb-ft (908 Nm) with no derating required for continuous duty operation. Its compact housing keeps clearance issues to a minimum, while a ductile iron bearing cap, 117% stronger than the gray iron used in the predecessor 870 Series, and an o-ring sealing configuration between the housing and bearing cap improve clamp load and resist vibration. The 871 Series offers nine speed ratios and thirteen output options, including SAE B, SAE BB, and SAE C pump spline configurations. Shaft power reaches 64 HP at 500 RPM and 128 HP at 1,000 RPM. This unit also supports Wet Spline, SmartStart, and Quiet Gear options, the only Chelsea PTO series to offer all three.

Additional Information
The 871 Series replaces the Chelsea 870 Series PTO. Upgrades include a ductile iron bearing cap rated 117% stronger than the gray iron used on the 870 Series, plus an o-ring sealing configuration to improve clamp load and reduce the effects of engine vibration. The 871 Series is the only Chelsea PTO to offer all three of the brand's signature options simultaneously: Wet Spline (extends PTO and pump shaft life), SmartStart (reduces shock load at start-up), and Quiet Gear (reduces operating noise). Typical markets include fire and rescue, truck cranes, pumper cleaner, and refuse equipment.
