Pilot bearing installation?
So I'm almost finished with my first engine swap and I'm putting the pilot bearing in with a deep well socket as I have read from other threads and as I'm tapping it in into the e-shaft it deforms. I've already ordered a new one but I don't want to have to keep buying them if I'm doing something wrong? I don't see how this could be the cause but should I have installed the pilot bearing before cranking down the flywheel? Has this happened to anyone else, since I haven't been able to find any threads on it?

Is it possible that too much grease might be the issue? There was plenty of Hi-Temp grease. I guess I will measure the ID of the e-shaft and the OD of the pilot bearing when I get the new one in but it was not tapping in.

Make sure the inside of the E-shaft is clean and smooth. Any roughness or burrs can keep it from going in properly.
Also, having a good install tool helps, Mazdatrix has one -
Tools
I have one that some guy on the list back in the day made, it's FAR superior to using a deep well socket.
The outside of the bearing only needs a light coat of grease to slide in. You may want to get it started with something flat like a block of wood between it and a hammer, get it down as far as you can THEN get the socket involved.

I didn't see or feel any burrs or roughness before I tried to put it in but I'll check again, maybe clean it up and give it a brief polish. I was thinking about the tool from mazdatrix I'm just having a hard time justifying the price after shipping for a one use tool. I was about to use a block of wood but it started creating wood chips and dust so I'm thinking to stick with a soft metal. I was only able to get it in about halfway before it just basically stopped. Just doesn't seem normal, I almost wonder if the one in the clutch kit was the wrong size or something.

Cleaning the bore is definitely important. I also lightly coat the bearing sleeve with just a little grease. I don't have a tool but have put a few in using a sheet metal hammer for it's large flat head. It's also light and easy to control. I'm really careful to start it straight starting with very light taps. Once your confident it's started straight you can increase the force a little, but it takes patience. To get it counter-sunk enough for the dust seal I use the old bearing on the new one. You don't have to go in very far. Works for me, but that's not to say the PROPER tool wouldn't be the way to go.

Ha, yeah Adam C I know what goes in first. I'll clean it up and polish a little and try the freezer trick (should have done that in hindsight but a thread in the FC forum made me think a little extra force was normal) if that doesn't seam to work for it going in easy I'll buy the tool or make one. The old pilot bearing is in the old engine and I have not tried to extract it yet but now I also have the mangled one too. Thanks for the help guys I think I know where I need to go with this.
