Medic, you mention in your first post that the first thing you did after installing the engine/transmission unit was to try the clutch, and I just want to double check that you did this before starting the engine for the first time. I ask, because if you start the engine for the first time, with the clutch cable unhooked (clutch arms free to move about with no resistance from cable, omega spring, and so forth), release bearing fork can move enough for the release bearing to come off of the fork. Unfortunately, I know this from experience, and got to do a gut punch, "do over" for that very reason.

Once the release bearing and fork are situated correctly, and the fork arm is not allowed to move around after that, there really is no way for the fork to come off of the release bearing.
