**** pilot bearing
Does anyone have any tips on how to get this out?
I've been at it for two hours now, I tried the wet toilet paper trick, I tried drilling it out (would take too long, and I don't have the right bits), I made my own puller out of a valve spring compressor, the crank balancer and some cat 5 cable, that just tore the cat 5 cable. Yes, it tore 6 strands of cat5 cable. I would just cut it, but the only saw blade that is small enough to get in there is my jig saw, and I don't have any high speed metal blades for it. I'm trying to get this done tonight. Is there anything anyone can think of?

A slide hammer will work. You may only be able to get one of the claws inside the bearing, but it'll come out with ease.
I might add, when you are ready to install a very simple way is to get a ball peen hammer, put the ball against the bearing and tap it in using another carpenters style hammer.

Get a tap the right size I believe a 5/8" standard will fit. If it don't drill it the right size. Run it in until it bottoms on the crank and keep turning. It will jack it out.

Yea, this was the initial plan... I even had a tap & die set ready to go. Biggest tap, 1/2".

I guess I'll pick one up tomorrow. Thanks for the help guys.

This is the way I do the TP trick, it has worked every time I have done it.
Soak the TP in a bowl of water and stuff it in the bushing till you cant stuff any more. Hammer in the soaked TP with a 3/8 wratchet extension. Keep repeating this. The wet tp (in a hydraulic manner) WILL force out the bushing. You will be beating it pretty hard until its cracked loose. This will work, it may take a few minutes but give it another try.
If all else fails go to autozone and rent the slide hammeer and puller.
Most people that have problems doing this eiter dont get the TP wet completely soaked or dont use enough of it. You will be amazed how much wet TP will get pounded into that bushing.

I tried the TP method three times for a total of 4 hours. I have a near perfect fitting ratchet that I was able to use, but the toilet paper still kept finding a crack to escape. I was hitting it pretty hard, when the TP came shooting out it felt like getting hit with an airsoft gun.
I'm pretty sure the bearing was damaged when I removed the transmission. The jack holding the transmission shifted after I removed the tranny crossmember and the tranny dropped three inches. I figured the bellhousing bolds would've absorbed most of the shock, but I guess the bearing took some too.
I tried drilling it out too, but my bits were stolen along with my drill about a week ago and I only had a set of wood bits and one total POS masonary bit. The masonary bit was taking two years and a day, so I gave up.
Anyway, I'll just get a tap from the hardware store. I think that's probably the best way right now. If that doesn't work I'll find a high speed steel blade for my jigsaw and cut it out. If only the sawzall blade would've fit, I've got a million blades for it.

Re: fing pilot bearing
A couple of helpful hints....
-Post in the correct forum. Pilot bearings don't belong in "LT1/LT4 Engine Tech".
-Tone down the topic a bit in the future.
Moving to "Drivetrain"....

Re: **** pilot bearing
Is it a roller bearing or a bronze bushing? If its a bushing you can use a wood bit in your jig saw the bushing is very soft. If its a roller bearing the tap or a drill wont help you.
Re: **** pilot bearing
i fill the cavity with grease, then take a socket that fits inside and give it a good sharp blow. works for me every time. just make sure you clean the grease out before you put the new one back in.

Re: **** pilot bearing
there is a pilot bushing removal tool that you can usually rent i know for sure at advance auto parts have used it several times, it is a puller designed specifically for this. Also if that doesnt work for you, get a chissle about 1/2'' in wide or smaller and use a sledge hammer to split the bearing in half. ive used both of these methods several times.
Re: **** pilot bearing
when I did the bushing it was on so tight that it broke the slide hammer tool. The guy that was helping me came up with the idea of chiseling it out. He just hammered around the corners of hte pushing, and eventually it start breaking apart... and walla it was out.

Re: **** pilot bearing
Well I tried everything. Even a blade for cutting steel in the jig saw was not making it very far. I did however find a wonderfully elegant solution.

Took 5 minutes. Anyway, the new one is in, and the clutch is installed.
