Hi all -- I'm reinstalling my new throwout bearing on the carrier, in anticipation of reconnecting the engine in trans in the very near future. I wanted to ask about whether I could press the bearing on the carrier myself (in a vise) using a block of wood against the bearing and centering the carrier on the opposite side of the vise. I plan on using just a thin coat of grease on the carrier just to reduce friction, unless it is advisable to press it on dry. Lastly, I remember a trick, mentioned on this forum I think, where you freeze the carrier, and place the bearing on a lightbulb, then because the carrier is contracted and the bearing expanded, it slips on fairly easily. Is this just an urban myth, or something I should try to ease reassembly? Thanks!
 
My recollection is that some think the bearing should be rotated as it is pressed home. I can't speak from experience as I just had my usual machine shop press it in and whatever they did was fine.

If you have a good relationship with a machine shop they might do this gratis while you wait (or maybe my guy was just being nice to me).
 
I just mashed mine together in the vise, seemed to work fine. I suspect the extreme methods are only needed for the later cars with the steel carriers, instead of brass.
 
I plan to replace my T-O bearing as part of the project I'm working on. Not there yet, but reading all procedures posted here with great interest. The question occurs to me: if this thing is so hard to press together, what's a good procedure for getting the old one off the carrier?
 
I recently did mine, I bought a new sleeve and bearing and pressed it in a vise and it works fine.
 
That sounds fine, I think I'll just do it myself. The way I removed it was in my vise as well, and just pressed it off. I found a PVC pipe about the same diameter as the carrier, and placed that against the carrier on the side where the TO bearing contacts the levers. Then, on the opposite end, I placed two chunks of wood both of equal width and in between the back side of the TO bearing. As you start to compress it, with not too much pressure, POP!, the bearing separated no problem. It looks like it doesn't take that much pressure to combine, I was more worried about uneven pressure on the bearing race that might contribute to accelerated failure. I think it'll be fine.
