Pilot Bushing/bearing Removal??????????
Need suggestions on the easiest way to remove the pilot bushing from a big block crank?? I'm going with a roller bearing.
Thanks

A method I have successfully (every time) used for over 40 years. Find a dowel (6-12" long) that just fits the pilot bushing. Full the cavity with grease. Put the dowel in the bushing and hit it very sharply with a heavy hammer. Hydraulic pressure WILL push the bushing out.

I had heard old mechanics talking about doing it this way, but I didn't know if it actually worked!!

Works like a charm.

Keep adding grease as you go and it will push right out.As said above a 5/8" course thread bolt threaded in works also.

Also, I don't know what kind of trans you're using, but I heard you're not supposed to use a roller bearing with a Muncie. This is what I read from another post on pilot bearings and Muncies:
The explaination I've heard, from Lars actually, was that the tolerances on older transmissions like the Muncie aren't very tight and the pilot will see a lot more perpindicular forces. A roller bearing has a higher failure rate in this scenario and when it fails....not good. A bronze bushing isn't really going to fail, so to speak. It might open up a little but the input shaft is still going to spin freely.

Just did the same Keisler conversion. Someone already mentioned it, but the tool you get at AUTOZONE works like a charm, and you get your money back when you return it. If you like the way it works, you can keep it for the small rental fee that you paid. Also, if you do decide to keep it, you can turn it in for a brand new one. That's what I did.

The Matco puller works!! From using a slide hammer, the back of the bearing was chamfered and canted in the hole. The tough jawed Matco puller straightened it out and out she came. After all I went through getting a puller that would handle my tough job, the Matco puller was head and shoulders above everything else I tried. If you pull pilot bearings often, this tool needs to be in your box.
