The Chelsea 871XBQTP-B5RK or 871XBQTPB5RK is a 10-bolt PowerShift (hydraulic shift) Power Take-Off from the Chelsea 871 Series, designed for Allison transmission applications. Continuous torque capacity reaches 670 lb-ft (908 N-m) with no derating required for continuous duty use. The series offers nine speed ratios and thirteen output options, giving installers a wide range of configuration choices. A ductile iron bearing cap, rated 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap address the vibrational stresses of modern engine designs. The compact housing height helps clear tight installation envelopes. Call us to confirm proper fit and configuration for your specific application.
