5.15.Confirm that the hydraulic pressure has been relieved by rotating the brake drum / hub assem- bly. If the it will not rotate, confirm that the brake is released and that the brake linkage is not bound.

5.16.If there is any possibility of fluid contamination, drain and flush the system, and replace the filter before installing the new hydro pump.

5.17.Position a catch pan beneath the hydro pump to be removed. Have four 1/2” JIC plugs and two 1/2” JIC caps within reach.

5.18.Disconnect the feed line that runs from from the front of the hydro pump to the filter manifold using a 7/8” wrench on the nut, and a 13/16” wrench to hold the fitting on the hydro pump. Plug the line, cap the fitting on the pump.

5.19.Disconnect the return line that runs from from the outboard side of the hydro pump to the res- ervoir using a 7/8” wrench on the nut, and an 11/ 16”” wrench to hold the fitting on the hydro pump. Plug the line, cap the fitting on the pump. See Figure 5.14.

5.20.Disconnect the two lines that connect the hydro motor to the back of the hydro pump using a pair of 7/8” wrenches. Plug the lines.
