When replacing a power steering pump the main drive pulley MUST be removed and reinstalled onto the new replacement pump. This pulley is pressed onto the input shaft of the pump which then in turn drives the inner pump workings. This connection allows the engine to transfer its power through the serpentine belt which is fitted over the power steering pump pulley.


Power Steering Removal Tool

The tool will take up about 12 inches in front of the pump so you must either clear remove in front of the pump or remove the pump mounting to allow room. Once this has been achieved and there is sufficient room in front of pump attach the removal tool by fitting the tool into position and using force to turn the press.


Removing Power Steering Pulley

When the tool starts working you will here a "pop" informing you the pulley has started moving. Continue this action until the pulley becomes free of the pump input shaft. Once repairs have been made and the pulley needs to be reinstalled its best to first warm the pulley to about 120 degrees F.


Checking Pulley Temperature

Make sure the shaft the pulley will be installed on is clean from rust and nicks, this will make the installation processes more difficult. If debris is present use a small piece of sandpaper to smooth out the surface be fore installation. DO NOT LUBRICATE THE SHAFT OR PULLEY. If grease or oil is present clean thoroughly before installation. Anything but a clean surface can cause the pulley to slip which would create a failure.
