It should be between .037 and .043 INCHES
Scanned the last couple of pages of your thread on the Vortex and didn't see anything about the pilot bearing. I probably just missed it. What problem are you having? Is there one in the end of the crankshaft or something? Some Audi's have this issue depending on the transmission.If by chance this is the problem, there is a special little tool that can be used to remove it. However, there is something else someone discovered to remove the bearing without the special tool. If I understand correctly, you can fill the hole and the area behind the bearing completely full of grease, and then used a shaft that's the same size as the hole in the bearing, and tap it in there with a hammer. This way the bearing is "hydraulicaly" removed from the hole.
You can get a loaner pilot bearing puller for free from chain stores. If worse comes to worst, you can cut the outer shell using a dremel.
the one i had to pull was full of roller bearings, and the races disintegrated and the needles went everywhere.. it was a pain to get out..
I guess you don't know the drift+grease trick to get the pilot bearing out...
...BTW your Bieber avatar is awesome.-Malone
I did not know about the drift+grease trick until AFTER I had already destroyed the innards of the bearing.
Yeah, this whole project has been a study in "Leave well enough f***ing ALONE!"
