You will need the special tools from CAT. They aren't cheap, you may want to have a shop change them.

Its a threaded bar stock piece that actually screws into the cup.You adapt a slide hammer to the top and pull them.As long as there are No clearance issues its a easy job.Dont forget to drain the coolant first.
