10mm, 13mm Sockets and ½” or 3/8” rachet to suit
Small Breaker Bar ½” drive
Bent External Circlip Pliers
Hammer
Vice (100mm / 4” jaws required)
Center Punch
Assorted Larger sockets to drift bearing from pulley.
Parts Used:
NACHI bearing No 30BGS10DST2 or 30BGOSS2DS
Pulley and bearing removal procedure:
Remove top of radiator cowl
Remove compressor cover plate
Turn ignition and air conditioning on (don’t start the motor!)
Start to undo 10mm bolt retaining pulley
Turn off ignition.
Undo drive belt idler pulley by undoing but not removing the 3 10mm bolts.
Remove the center retaining bolt on compressor, being careful to note and not lose any shim washers on the bolt.
Slide the end cover of the pulley toward the front the vehicle and carefully remove, once again taking careful note of any shim washers that may be present up the spline in the center of the end plate.
Using the bent circlip pliers carefully remove the circlip retaining the pulley and bearing.
Slide pulley forward and off the center shaft.

Bearing replacement:
Find a socket that has a small end that will just fit into the center hole of the bearing. Sit the pulley on a flat support or vice jaws, making sure they are just wide enough apart for the bearing to be pushed out without hitting the jaws. Place the socket into the bearing and using a 2lb hammer proceed to carefully drift the bearing from the pulley. Do not use excessive force, use just what you need to get the job done. As the bearing is moving, make sure you drift it so it remains straight in the pulley.
Once removed you get to clean the pulley and make sure you remove any burrs that may make it hard to fit the new bearing.
Carefully line up and gently start pushing the new bearing up into the pulley using very light taps with the hammer. DO NOT hit the center of the bearing! Always only apply pressure to the outer shell of the bearing during this part of the job. You are just trying to line it up straight and push it in enough to hold it before the next stage of the job. Make sure you get it as straight and evenly centered as you can. Using the old bearing, place the pulley, bearing and old bearing in the vice and use the vice pressure to push the bearing into the pulley. All the while ensuring it is straight and even. Try to use continuous and even force and ensure you push the bearing fully into the pulley. When you are sure you have it, remove it from the vice and check to see the bearing is hard up against the shoulder of the pulley. You will notice some small dints on the pulley. These were there to retain the bearing. Using a center punch, lightly pop in these dints to spread them back over the edge of the bearing to retain it as before. One pop in each dint will do just fine.

Reassembling the pulley to the compressor etc is just the reverse of the dismantling procedure.
Make sure you get those shims back where they originally came from.
DO NOT over tension the drive belt or you will be doing this again in a few months time.
You have just saved your self a swag of money!
