Chelsea 870 Series is a hot shift PTO designed to fit Allison and CAT 10-Bolt transmissions. It has the highest torque capability in the smallest package available – up to 670 lbs-ft. It is as robust as the 890 Series, but without the extended shaft.

Power density is for what the Chelsea 870 Series Power Take-Off (PTO) is known. This series utilizes a compact housing that helps eliminate clearance issues, but employs robust moving parts to ensure the best performance. It is available only for 10-Bolt applications that have a high torque requirements and a demanding work load. Two assembly arrangements are offered to maximize installation clearance. High capacity bearings and superior gear designs provide torque ratings up to 670 lbs-ft for the ultimate performance. There is no need to de-rate the PTO for continuous applications. It features six shift options, four of which are integrated into the PTO housing that require one hose for a simplified installation - the hose is included with the PTO. Our popular Electronic Overspeed Control (EOC) is also available to protect the PTO and driven equipment. Eight internal gear ratios provide a wide variety of speeds to meet virtually all application requirements. Direct mount pump flange options are also available with our Wet Spline Technology that provides increased PTO and pump shaft life. Versatility, power, ease of maintenance and installation make the 870 Series the BEST choice for Snow and Ice. Refuse, Aerial, and Defense truck requirements.
