Easy step by step guide on how to remove a typical power steering pump pulley, though appearances may vary the process is the same for most vehicles.
Difficulty Scale: 4 of 10
Precautions: Never use a hammer to remove or install a power steering pump pulley
Before Beginning the Job
Step 1 - 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.
Step 2 - The tool will take up about 12 inches in front of the pump so you must
clear or remove the pump mounting bracket 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.
Step 3 - 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 re-installed' it's best
to first warm the pulley to about 120 degrees F.
Step 4 - 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 before 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.
Step 5 - Once the desired temperature has been achieved gently align the pulley onto the
shaft. Gently spinning the pulley will ensure a "square mount" which will start
the correct alignment before the installing.
Step 6 - By turning the pulley you can take the wobble out which indicates the pulley
is square. Next connect the installation tool to the front of the pump input shaft.
Step 7 - Once the installation is inserted tighten the collar against the pulley. Then
continue tightening with wrenches and a ratchet.
