Default pilot bearing install

Does anyone know right off hand if the new pilot bearing should be 'flush' to the surface next to the crankshaft or if it protrudes out of the crankshaft slightly? If it's not the ladder, I believe I have a new problem to solve...

The pilot bearing should be flush with the end of the crankshaft as it goes inside the crankshaft.

Did the old one come out in one piece? Any chance it didn't and you left something in there???

Also verify you got the correct one.

I placed mine in the freezer overnite and it went in without any trouble....

Stock crank?

If yes, did the seal behind the pilot bearing move? How did you remove old one?

I hammered it pretty hard, but it's still not flush.

I did too! Had it in the super-duper-industrial freezer ( ).
No, it came out with a die-grinder after breaking two pullers. I thought I had everything out behind it, but maybe not...

... I was unaware of the 'seal' you speak of. Can you tell me more?

There is an oil gallery plug in the crankshaft behind the pilot bearing.

What type of pullers did you use? A pilot bearing puller typically takes care of the job. I would be afraid to use a die grinder around the crank like that.

I tried the cheesy two-prong pullers, broke two, then went for the air tools.

So, based on the modified drawing below, would you assume that if I can't get the new bearing in with repeated blows with a hammer (assuming it is the right bearing), I have something lodged between the seal and new bearing?

I thought you wanted to know if the 'seal' itself moved, not something foreign in between the seal and the bearing.

Are you asking if I removed the old seal? If so, I definitely did not. I'm debating pulling the bearing again, and getting a better look at what's behind this thing...

Buy (or rent) the correct tool for the job. You've got more ball$ than me using a die grinder in that area The bearing should be installed flush. I would remove the bearing (you'll have to buy a new one), get the correct three prong puller, and investigate.

believe me, if I could locate the correct 3-prong puller in the area, I certainly would. I'm probably going to have to order something and have it shipped...

I'll keep investigating. With any luck, I can locate the proper puller and see what's what.

I don't have any pics but the "correct" puller is not 2 or 3 prong. It is a device that has a threaded end that expands at the end and grips the pilot bearing from all the way around. Comes out no problem and I've replaced it twice in my car. Those 2 or 3 prong ones are horrible.

I rented mine for free from the local auto parts store.

You are correct, I just checked mine, and it is two prong. Sorry for the confusion.

Autozone, O'Rielly's, Advanced Auto... only two had pullers for rent and both were the cheesy 2-prong kind.
