The Chelsea 871XJQTP-D3AC or 871XJQTPD3AC is a 10-bolt PowerShift (hydraulic) Power Take-Off built for Allison transmissions. Part of Chelsea's 871 Series, it delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous-duty applications. The compact housing height keeps clearance concerns minimal, and nine available speed ratios plus thirteen output options give installers broad flexibility across fire and rescue, refuse, pumper cleaner, and truck crane applications. The ductile iron bearing cap is 117% stronger than the gray iron cap used on the earlier 870 Series, and an O-ring sealing configuration between the housing and bearing cap reduces vibrational effects and improves clamp load. Wet Spline, SmartStart, and Quiet Gear options are all available within this series. Call us to confirm the right configuration for your application.
