I'll move your topic to Forced Induction for you.
The shaft will tap out, but I prefer to use a press. You'll HAVE to have a press to reassemble the nosedrive. And you need to carefully measure the depth of the triple-pinned coupler plate in the ND for reassembly reference later. It'* the only way to determine if you are fully pressed in later.
On an older M62, do NOT buy the more durable longer-lasting seal. It has a hard time mating to your high-mileage grooved input shaft.
To remove the needle bearings in the inlet side of the case for the rotors, you have to drill/tap the bottom of the case and use a grease fitting to force the bearings out under pressure. Again, you need a press to reinsert them. Make sure you note how deep they're inserted before you re-press the new bearings. They don't go all the way.
As you can see, my nosedrive rebuild page isn't complete:
But this one is:
Note that I haven't fixed the links for the pics since I moved the pages from my server to the BC Forum server. If you want to view the other pages, just change the EXTENSION page name before the HTML, keeeping the bonneville forum link address prefix.
