Before you install your compressor cover, there are two final measurements you should make to ensure all parts have the proper clearance. The first is the end thrust. Place a small flat piece of metal, such as a turbo nameplate or flat washer, on the end of the turbine shaft. Place the magnetic base of the dial indicator on the bearing housing flange or some other close point of anchor and position the dial indicator on top of the plate. Using your hands, thrust the turbine wheel up and then down to check the thrust movement of the rotating group. Compare this to your specs. Typically you should see approximately 0.003 inch. If this is in spec, you’re almost home.
