What is the needle bearing in the back end of the crank called? Is this the throw out bearing?
I am building an LS2 402 stroker,,, And I have a McLeod clutch. Today, I noticed that the 402 has no such bearing in the back of the crankshaft, while my LS1 crank does. Obviously, I need this bearing removed from the LS1 crank and installed in the LS2 crank,,,
How do I remove it from the LS1 crank?

Yeah, those are a PITA to remove. Even if you could get it out without breaking it (doubtful), it needs to be changed everytime you change your clutch.

For the most part. Some of the cars out there with higher mileage and more age that just wont do it. Or in some cases when the needle bearing material has collapsed and there is nothing but the outer rim to grab (you cant really get a grip on this). I highly recommend taking a chisel/sharp flathead screwdriver and a hammer begin by busting out the needle bearing center if it still intact. Once that has worked its way out, start chiseling the bearing on the 12 4 and 8 oclock positions evenly. Once the bearing breaks once its cake from there and you can just tap it to pieces. This method takes a max of 3 minutes and I have found it more effective than anything else I have used. Although I have seen people have great luck with slide hammers and the puller tools. The thing is, with the method I have given its guaranteed. Just be sure you don't slip off the bearing and punch through the damn plug right behind the bearing!

The only time I've seen the specific pilot bearing pullers not work is when the user doesn't have the "fingers" adjusted correctly. A slide hammer seems like excessive force to me, but whatever. I like the puller tool.
