    I've searched and searched, and can't seem to figure out what to do.
    I've fixed this twice, and the clutch linkage still doesn't work correctly...
    F134/T90

    I don't see where the throwout bearing has a hole to accept the return spring. There is one in front of the bottom ear of the throwout bearing collar, but when the spring is attached there, that pulls on the bearing and tries to rotate the throwout bearing which lets the clutch fork fall off the pivot. The only photo I've seen has shows the spring coming straight off the bearing retainer of the T-90 to the throwout bearing. So it looks like if the ears of the bearing go at 12 and 6, there should be something at 9 to receive the spring. But I just don't see anything on the bearing collar that will take the spring. There is a very small tab on the collar against the face of the bearing, but there isn't any hole for the spring to attach to.

    What am I missing here? :? Do I have the wrong throwout bearing?

    Here are a few pics of the throwout bearing I have...
    As far as I can tell, the squared off side of the throwout bearing collar goes on the side with the clutch fork. The small triangular tab on the left is where it looks like the hole should be to attach the return spring. But we've cleaned and de-greased it and probed with needles and there's no hole there.

    And I've remembered that's the original bearing collar with the new collar. So now I'm even more confused...

    well i went to the garage to compare notes with my bearing,and it appears that the bearing thief has struck again :rofl: i believe you have a "almost correct bearing" as i recall mine had a tang with a hole in it for the spring to hook in,maybe some one else will have a picture of the correct one,as for me looks like time to change the locks on the garage,just cant stand someone moving stuff around :mad:

    Here's an L-head bearing. I'd just drill a hole in that little tab and stick it in.

    X2 on drilling the hole.

    This is a throw out bearing from a T-90/F-134

    Will this work? Notice the tab on his is horizontal and your tab is vertical. Also the tabs are on opposite ends of the barrell. (Please disregard. :oops: I looked at the bearing inquestion and see he is talking about the tranguar tab)

    you said earlier that you degreased it,hopefully just the outside of it,if you soaked it in something throw it away,and buy a new one,without lube it will fail prematurely

    Well, I'd be concerned about drilling that tab because it's about an inch further forward from where the actual tab is supposed to be. I think I already over-stretched the spring when the fork popped off last time. So I'm just going to go ahead and order a new (correct) collar and bearing, as well as a new spring.

    And I just used a bit of degreaser on the tip of a Q-Tip to make sure there wasn't a small hole on that triangular tab. I definitely didn't soak it. But the bearing isn't turning very well, and wasn't when I just pulled it (even though it has a grand total of about 150 yards on it), so I'm just going to replace it anyway.

    Thanks for the help... I thought I was losing my mind there for a while!

    So, quick question. I'm installing the new bearing tomorrow and have a question about adjusting the linkage. I see in the book that it says the pedal should have 3/4" - 1 1/4" of free play in the pedal. Can I assume that's until the clutch starts to disengage? When I did that last time, it seemed like I was taking a lot of the play of the return spring, and the bearing was pretty close to the clutch at that point. Any pointers for properly adjusting this? Anything I should look for? Tips?

    Thanks!
