Power density is for what the Chelsea 877 Series Power Take-Off (PTO) is known. This series is constant mesh for applications that do not need to disengage like when using load-sense pumps. It 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 requirement 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. The robust design of this PTO provides all the power necessary to get the work done. It features pressure lubrication integrated into the PTO housing that requires one hose for a simplified installation - the hose is included with the PTO. Eight internal gear ratios provide a wide variety of speeds to meet virtually all application requirements. Rotatable 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 877 Series the BEST choice for Snow & Ice. Refuse, Aerial, and Defense truck requirements.
