    Yeah the seals inside the bearing have had it Mikey. You are gonna have to slide the TO off the slave cylinder and replace them.

    Yeah that is supposed to spin free. What you are checking for is to make sure it is SMOOTH when it spins, and that there is no play. Any roughness or play, and it needs to be changed out.

    Before I sign off for the night, I want to thank EVERYONE who posted here to assist me, either with technical guidance or simply with words of encouragement - it all helped me, believe me when I tell you that.

    As I mentioned a few posts back, I have absolutely zero mechanical background (I have an Engineering degree which does somewhat help), have never worked on any car (excluding oil changes) and when I bought this thing about two years ago I would have told you that you were crazy if you were to tell me that in two years I will have the clutch apart in my own garage. I live in a small city where there are less than ten Ferrari owners, and no Ferrari Service Shops (closest is about 150 miles away), and because I am meticulous I did have some anxiety and some apprehension for that reason alone, but in the end my passion for this car trumped everything.

    Thanks to the 348 Brotherhood, I have learned how to do so much (so far) and hope to learn much more.

    I have some advice for anyone who is in the market for a Ferrari: You either better have a fat pocket, or you better learn to do some wrenching because either way these cars will need it. I chose to learn how to wrench, and if I can do it anyone can.

    I have no problem with doing just that - after all, you got me here this far so there is no turning back without completing the job. :):)

    Sounds good Ernie. I will give you a call to discuss this to make sure I am checking this properly. It definitely spins smooth, with no play, and no roughness, but as I mentioned it will only spin when I give it a whirl with my finger and quickly come to a stop shortly after.

    One thing I almost forgot - very important for a newbie (read "amateur") to be very organized, so I laid everything out on the garage floor with notes listing the sizes, quantities, and where it belongs when re-assembling. I know Steve (TheOnlyest) has a good method also, he uses zip-lock bags and labels them.

    I still cannot figure out where the leak is coming from, but I suspect it might be from this seal. It is actually the only seal I can see on this bearing, no other seals visible/tangible (excluding the orange one buried when looking at it straight it on).

    Hard to tell from the picture, but that seal is far from perfect. It is worn down on the open edge of the bearing (top edge in the first picture), where the light is making it shiny. It is worn/eaten all the way around.

    The TO bearing I have is part # 144954, I am not sure how many seals that is supposed to have but I only see one (the corroded one I described).

    I thought I saw one that four blue seals inside of it?

    Change all of the seals inside the TOB.

    Sorry I didn't get your call yesterday Mike, I was getting ready for work. To answer your question about the triple seals, to change them or not. It's up to you bro. Me, I changed mine because they were leaking, and because I was in there anyway. But since you said yours weren't leaking I guess you could let it go until they do start to leak. You know what they say "if it ain't broke don't fix it". Besides now that you know how to get at them it wouldn't be a big deal to do them if/when they do go south. It's what ever you feel comfortable with Mikey.

    On a side note, you may want to see if your camera has a setting for taking pics up close. Mine has a little flower icon for that setting. That way your pics will be clearer and it'll be easier to tell what the problem is from our end.

    Anyway, awesome job buddy!!! Keep up the good work, you're almost done.

    Thanks Ernie, time for a new camera for me as I have no such setting :):)

    The triple seals are right there, I might knock them off while I am there.

    I just removed two seals from the TO bearing. Those are the only two that will come out, there is one that is orange that is sealed right inside, pressed right in.

    I think I finally understand what I am looking at. The two seals I removed are what I believe # 35 (part # 151822 GASKET) and part # 33 (part # 139438 GASKET or SEALING RING).

    #35 in the first pic is the larger seal (on the left) and # 33 is the smaller seal (on the right)

    #35 is the one with the red arrow in the second pic.

    #33 is the red circle in the third pic.

    hey guys, thought i would chime back in. Looks like this is carbon copy of mine. There are 3 seals total in the T/O assembly if i remeber. Call and order them, they just pop in/out in under 30 seconds.

    I bet your triple seals ARE leaking based on what I see inside the bellhousing. They are cheap and easy to do. Do it now unless you don't mind taking this all apart next year. If they do start leaking heavily in the future you will have to add the cost of a flywheel repack to the bill as well. Spend the $50 and do the seals NOW

    PS Ernie is a great coach.. I wouldn't dare start wrenching on mine until he called and gave me a little pep talk..

    just my $0.02

    Mine only had two that would come out. I better have another long hard look.

    I believe you, and since it is exposed and I am right there, I think it is a "cheap" fifty dollars to spend, if you know what I mean.

    +348 to the power of 348 :D:D

    might only be 2 seals but 3 sticks in my head. maybe the 3rd was a dust seal?? #33 and 35 will fix the leak. The other one I just did because I was there

    Thanks for this. I want to replace as much as I can while I am in there, I really don't want to go back in if I can settle everything now. Is that # 34 scraper ring in any of the pictures I posted that you can point out? Or do you have a pic of it somewhere that you can post?

    Then knock out those triple seals while your are in there. It's a 15-30 minute job, depending on how long it takes to trim up the plastic to wrap up the shaft with.

    A few updates boys, but before I do I just wanted to show some wear on that plate that has the fingers on it. I was a little concerned about this, but after speaking with Ernie he reassured me that this is normal wear and tear....and if they snap, then we can get a new one for $125 (thanks to Plugzit, FatBillyBob, and Ernie).

    If you look close you will see the grooves closer the the centre of the circle.

    Now, for some show and tell. Ernie suggested I remove the gear inspection plate and have a look to see if the gears are staked (I may not have the terminology of this correct, so if I do not can someone please step in and correct it :))

    Ok, the inspection plate consists of two 13mm nuts (you're gonna luv my nuts :D:D - sorry, couldn't help it :))

    Once I had those two nuts off, I had a hell of a time getting trying to get it off because it is wedged in there tight between the bottom of the gearbox and the bottom of that flange sitting on top of it. After struggling with it for about five minutes with a regular screwdriver trying to pry it out, I had no such luck so I found the perfect tool...we will call it Ferrari Tool Especiale # 9162010 (representing today's date :D).
