#8 nose bearing... need help with getting seal out

[x98boardwell]

With this being "free" I'm having a hard time removing the old seal from the #8 bearing which seals against the crankshaft.

I want to avoid putting this in the vice so I was hoping there is some guidance as to what I can do to help gain leverage and remove this older seal.

I provided it to the machine shop on the shaft still not realizing otherwise I would've removed sooner.

Lastly, should I install on the bench before I reinstall on the crankshaft before buttoning up the case halves or wait until case halves are sealed/togther? I would think on the bench would be easier as I can pound it in evenly while it's sitting there...

Thanks for any help!!

Slip it back on the crank nose and use a screwdriver to pry it out.
Install the new seal on the table. I use a large socket to tap it in evenly.

Wouldn't that put more stress on the shaft itself since it's not in the case and just on the table for the most part?

Stress on the end of the stout hardened steel crankshaft? Is that what you are worried about?

The question I have is why do you want to remove the seal?

You should be replacing that nose bearing.

Tyson, I did end up buying one... many people that I spoke to including engine builders stated they don't always replace and more times than not don't... It bothered me knowing how deep it was in the motor so I bought a new one...

Guessing pressing on the outer seal afterwards is ideal or should I install seal prior to laying crank in position? Not the green O-ring but rather the outer shaft seal.

Thanks,
Bryan

Historically, the nose bearing was not replaced during a rebuild absent some specific issue with the bearing. That probably is why it is not included in main bearing sets. They are very lightly loaded.

It seems they are now on the market at a relatively modest price - for Porsche parts anyway. I have three used ones sitting on my bench. Some idle day I'll check the bores. All three show some visible evidence of wear, the newest of them the least.
I'd really like to know what material they are made of, as it looks like it would be easy to bore and insert them, which would give them an almost infinite life.
