The Chelsea 871XJFJP-D3XV is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmission applications. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 Nm) with no derating required for continuous-duty use. A compact housing reduces clearance concerns at installation, and multiple assembly arrangements provide flexibility across a wide range of mounting configurations. Nine speed ratios and thirteen output options accommodate varied application requirements. The 871 Series succeeds the popular 870 Series, incorporating a ductile iron bearing cap rated 117% stronger than the gray iron predecessor and an o-ring sealing configuration between the housing and bearing cap to improve clamp load and reduce vibration-related wear.
