Pilot Bushing
I was reading a post from JohnZ and he gives the dimensions of a pilot bushing as 1.094" OD, 0.594" ID. I measured mine by putting a socket in the bushing until I found one that fit pretty good and then measured that and I get around .680", so unless I have something different, mine is pretty worn.
I have a pretty large set of tap and dies, but I don't have a tap large enough to use to pull the pilot bushing. I've heard about the grease trick, but that seams pretty messy. Do I remember correctly that someone suggested using "Play-Doh" and a dowel to drive it out? Or is there another ingenious way to get it out?
It's been a while since I installed a clutch. I found an old clutch aligning tool that I had stashed, but it fit pretty loose. I figured it was loose because my bushing was worn. Are they supposed to fit tight?

Although I've heard it for years, I've actually never "seen" the grease/dowel trick with my own eyeballs. I've had some guys tell me that instead of grease, they put wet toilet paper in the hole, and use the dowel.
Take a Dremel and cut it out. Make one cut at lets say 6 o'clock, and another at 12 o'clock. Be careful not to cut into the flywheel.
Take a small chisel or screwdriver and peck around the edges till it gets loose and remove it.

You can use a 5/8" lag bolt to self thread in the old bushing, then use the length of it to reef the thing out of the crank.

KCJohn,
I've used the bolt trick with great success. Here's Plasticman's topic on the playdough route where the bolt method is mentioned.

67L36Driver states to use a 5/8"-18 tpi bolt.
Here's some pics I just took of the last time I used this bolt method (thought I'd thrown it out). Worked slick for me.

I couldn't get the grease thing to work so I checked on the forum and found that Play Dough was better. No Play Dough in our house, so I tried a little rope caulk. It work great! And, it left the cavity as clean as a whistle! I was going to use window spackling, but it was too old and dried. Forget the grease.

I called NAPA about the pilot bushing and when I gave them the number PB-656-HD, they told me it was a needle bearing, not a bronze bushing. I guess I'll call some other places and see if I can find one.

Check the FAQs. The part # for the oiled bronze bushing has been posted quite a few times over the last few years. That is unless the part # you used is correct and the FLAPS is using a cross referenced replacement part.

Amazon has it!

It is a bronze bushing. They must have pulled the wrong part or they just stock one type and cross reference replacements.

I was able to find one at Advanced Auto. I had them check it before I made the trip and it is in a box that looks like it was made in the 70's. It was Federal Mogul brand and non magnetic.
The part number I used was correct (PB-656-HD), but the 3 NAPA stores I called don't carry it any longer. Their number showed a needle bearing from a different manufacturer. Advanced Auto checked their other stores and they all had one. So I guess NAPA is not the place to get one any more, or at least not here in my area.
I just turned a dowel on my lathe and I'm going to get some of my son's Play-Doh and give it a shot. Thanks to every one for all your help.

Wet scraps of paper incrementally placed into the opening, then take the largest socket that will fit and tap it into the opening... Do this repeatedly, filling with more wet paper and tap again. Eventually it will work out...just like the grease method! (and no mess...other than water)
Seen it, didn't invent it.
