The Chelsea 871LEFJW-D5TY is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmissions. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 N-m) and is rated for continuous-duty operation without derating. A compact housing reduces clearance concerns, and multiple assembly arrangements give installers flexibility in tight mounting situations. The 871 Series replaces the Chelsea 870 Series, incorporating a ductile iron bearing cap that is 117% stronger than the gray iron predecessor and an o-ring sealing configuration between the housing and bearing cap for improved clamp load and reduced vibration effects. Nine speed ratios and thirteen output options are available across the series. Common markets include fire and rescue, refuse, pumper/cleaner, and truck crane applications.
