For some reason, the throwout bearing easily slips past the diaphragm spring fingers (not sure if that is the correct terminology) of the PP.
I can turn the bearing manually and pull it back out past the diaphragm spring fingers just as easily as I can turn it and push it past it.
This doesn't seem right to me as the bearing should be able to push/pull the diaphragm springs when the clutch is engaged/released. In the current setup, when the clutch fork pushes this bearing to release the clutch disc, wouldn't it just push through the diaphragm? I don't want to install the transmission only to find out I missed setting this up correctly.
You still have the larger lip behind the fingers though?
Been awhile since I did my clutch with exact same setup but it doesn't look wrong to me from what I can remember, have you torqued down the PP?
The fork pulls the release bearing, it does not push it. The piston of the slave faces the front of the car. The fork end is pushed, the fork pivots on its hanger and pulls the release bearing towards the transmission.
Remember, the slave cyl and fork keep the bearing pressed up against the clutch plate at all times when everything is installed. So once everything is in place, the bearing will be kept in the "pulled out" position. The bearing and the PP sync and spin at the same speed always.
So being that it’s a pull type clutch. How does this puts extra pressure on the crank which may lead to crank walk?
OP, looks like you may have put too much grease on the release bearing. Wipe off any excess grease or it might get in the clutch disk and cause issues.
Yes, the large lip of the bearing is still behind the fingers of the pressure plate and the plate itself has been tightened down to specifications.
My concern was that I could relatively easily pull the bearing back and forth (perpendicular to the pressure plate) so that it would look like either picture noted above. Keep in mind that by pulling the bearing, it would never go past the larger lip of the bearing. The fact that this is a pull type of clutch system makes more sense as the bearing will never push the diaphragm so when the clutch pedal is released, it will naturally spring back to a resting position where the PP fingers are flat.
So I assume it should look like picture #2 when it is in the resting position? This will leave about an 1/8" - 1/4" of space between the clutch disc and the bearing. The stock setup didn't have this space as the bearing itself rested on the clutch disc. And maybe this isn't a big deal but I would think the disc would then have more room to float between the flywheel and the back of the bearing?

The only issue I have is that unlike your stock setup, the bearing in the setup in my photos can move back and forth about an 1/8" - 1/4" simply by pulling/pushing on it. When I look at my stock OEM setup, the bearing is as you noted and pushed up against the clutch disc at all times. The slave cylinder has to actually pull it out when the is disengaged (which makes sense since this is a pull type of system as others have commented).
I don't understand why the bearing can move back and forth in this setup as compared to the stock setup.
