View Full Version : LS6 transmission pilot bearing and removal tool - pics!

Just wanted to share my experience with removing the pilot bearing from a LS6.

Here is a pic of the removal tool attached to the pilot bearing - job done! Of course you will be doing this on the back end of the motor. This particular tool is 2-piece. You attach the gripper into the pilot bearing and rotate the nut until it is nice and snug. Then thread in the slide hammer to the gripper. A slide hammer is pretty self explanatory...slide it to the end you want the part to come out - bang, bang, bang.

Some have mentioned grinding the ends of the gripper tool because it doesn't fit into the bearing - hmm. Pop that pin out, angle it just right and get it in there. Put that pin back in place and tighten up the gripper tool.

Trust me it works! Also take notice to the small groove in the pilot bearing, the new one goes in like the old one came out.

Here is a pic of the pilot bearing with the bearing face that you see after you pull the transmission.http://i1058.photobucket.com/albums/t404/jaysenbaker/cts-v_misc/2013-09-01224349_zpsa59b240e.jpg (http://s1058.photobucket.com/user/jaysenbaker/media/cts-v_misc/2013-09-01224349_zpsa59b240e.jpg.html)

Here is the backside of the bearing that you don't see...unless you pull that sucker out.

Just a quick note, when installing the new pilot bearing...put it in the freezer for awhile. Put it in a ziplock bag. It helps to shrink the metal and makes installing it with a RUBBER mallet super easy, 4-5 gentle taps and it's flush - done!

Autozone and Napa both rent this exact pilot bearing removal tool.

Nice, but you might want to note that not all stores have that tool. Neither my local AutoZone or Advanced Auto had that tool when I checked a couple of weeks ago. So I wound up buying this, which fits our pilot bearings nicely:


$43. It's basically a copy of the tool sold by Harbor Freight, minus the case.

Awesome find! I inspected the tool at Advance Auto and the jaws were broken. So buying one beforehand is great planning and the cost is cheap relative to what you are installing.

Nice floor.

Thanks, lol. My garage floors are epoxy coated. The rest of the garage is pretty nice - I did a lot of remodeling.
