Replacing S54 crank hub

[marksae]

Okay, I was able to get it out. Like you suggested, I hammered it from a few different angles and saw that it moved a little, so I ended up just prying it a little at a time from the left and right sides until it came out. Now I'm having a really hard time getting the new one back in. I don't want to hammer it in and score the main bearing.

Okay, I'll give it a shot. I think the oil film in the main bearing might be making it stick as well. I'll try spraying some alcohol around it. Maybe that'll help dissolve that film enough give it a little more clearance.

There is a dowel pin to align it, that might be making it stick. Try tapping it with a hammer on alternating sides to jiggle it free.

There is a little screw in the middle holding it to the crank. I think it's a 4 or 5mm socket head, really long. That's what holds the sprocket on temporarily until the 4 big thicc bois that hold the vibration damper get installed.

Once you remove it the sprocket will just about fall off.

I did remove that small center screw. I thought the crank hub would just fall off, but it's stuck to the crank pretty good. I hit it with a hammer a few times and tried using a pry bar in several spots, but didn't have any luck.

The crank hub on my car has a broken dowel pin. So I decided to replace it. I thought I could just unbolt it from the crank and remove it, but it looks like part of it is recessed into the main bearing. I've tried pulling and prying, but it won't come off. Will I be able to remove this if I pull off the main bearing cap? I think it should give me enough access to pry it off the crank. Will unbolting and rebolting just one main bearing cap cause any issues?
