I'm putting my clutch together and I need to know how far into the clutch fork does the throwout bearing go. All the repair manuals I have do not cover this part. On my first go at it, I installed the bearing all the way on the fork, attached the fork to the ball stud and noticed that the throw out bearing was off center to the left. How should the throw out bearing be installed on the fork? How much "play" should there be initially prior to clutch adjustment? Thanks for your help.

when you install the tranny,the t.o.b.will move out the fork a little to line up. was the fork and bellhousing in the car before,if so did it work?I dont think you have a problem unless the throw out bearing has to move out of the fork more than a half inch,if so this may cause problems.are you using a blowproof?is it really of of the center when in the fork?maybe the wrong lenth fork?67rat member #199

Use a clutch alignment tool (5 bucks,wood,ok from the zone). It will put it close enough to fit the shaft.

Yep,
They're right. When you stab the tranny, that will center up the bearing.

The bearing "rides" on the input shaft collar of the transmission. The fork only controls the inward and outward motion. Be sure there is some white lithium grease inside the bearing collar to allow it to slide on the transmission smoothly.

Also be careful how you install the bearing in the fork. If you don't get the little retaining clips on the fork correctly, you will not realease.

The little ears on the TO bearing go under the fork lip, not over, as some people may think. It's kind of hard to describe, but hopefully you will know what I mean when you look at it.

I'll expand on Scooter's comment by providing a picture:

Thanks for all the responces. I have a Lake wood bellhousing and a Richmond 5 speed trans. The pivot ball is located exctly as the stock bellhusing. I have a new fork that is the same length as stock. I believe I have the t.o.b. on the fork correctly. When I put the trans in,it pulls the t.o.b. outward to where it's just riding on the fork. Is that correct install? Maybe I need to find out if Lakewood has a fork specifically for the bellhousing?

If I understand you correctly, That's where it should ride. Sounds like you're fine.
