just mah .02......i foudn another interesting way to do this....find a tight fitting bolt, and screw that in. if your not concerned about saving the bushing/bearing...it works well! you'll feel it bite, and just keep screwing untill the bushing comes off
..well...it did on a bushing anyway..
...thats how we got the bushing out of the camaro project we're on now.just thought I'd like to feel important is all....carry on....

Yea, I've done that with a bushing, it won't work with a bearing though as the bolt is softer than the bearing race and won't get a bite to thread the race.
That's going to be a 164 tooth bell with the larger flywheel needed to match. Depth is still going to be the same with the 390 input falling short of the stock pilot bushing. Better jump on that Boss 302 bushing while you can. The way that pilot bearing's made, it's bearing surface is even farther away from the pilot snout than a stock bushing is.

it will if you use a SOOPER HD bolt...
figured it wouldn't work on a bearing either. Funny thing is....when we did this, i just grabbed a random bolt laying around to get the size for a dowel...screwed it in...and we were like...HEY! lets just keep turning! lol

Yea, that is weird. You never know. I did a bushing like this after giving up with the grease method.
Hey All,
I just got that oversized pilot bushing (see pics). Question: how tightly should the bushing seat onto the trans shaft? Should it spin freely, should you have to tap the bushing onto the trans? Right now, its a very tight fit and fits easily only about 2/3s of the way. I think I could fix this easily with some light sanding, but don't want to if the bushing is supposed to be tight.
Also, any thoughts on knowing when its time to replace a clutch with a visual inspection? Since its apart anyhow I am considering replacement, but I've heard that everything needs to be rebalance (like balancing a wheel) when you replace the clutch disk and pressure plate. I definitely don't have the equipment for that so I was just going to reuse the existing clutch. No clue how the unit drives, this is all off a doner car.
Thanks again everyone!

Use some emerycloth to get the bushing to fit over the pilot shaft snout. Should be an easy slip fit. Drive it in the rear of the crank, put a dab of grease in the hole and snout and enjoy. Not a bad idea to replace the clutch disc while it's down. Pressure plates usually last thru at least two discs. JUst inspect the pressure ring before deciding. Also inspect the flywheel. You should not need to balance the clutch disc or pressure plate, they're neutral balanced by the mfg.
Finally installed the new pilot bushing today. Used some sand paper on the trans shaft and the bearing fit great. Comparing the new bearing to the exisiting one you can really see the difference, about twice as big. To remove the old bearing I rented a bearing puller and slide hammer from Autozone and it came out in about 5 seconds. Also replaced the clutch disc, installed the missing engine plate behind the flywheel, and bolted the pressure plate and bell housing back on. If its ever running we'll see if it all works! Thanks again for your help.
