View Full Version : Novice question re: Throwout Bearing/ Fork thingy

I have a pretty simple question or two here.

I'm re-installing an engine/tranny into a 66 Impala. (283/ 3spd manual)
It's purely coincidence that I've never, ever had to work on a manual tranny/clutch before so this particular job is new to me.

I've got my new Zoom clutch, pressure-plate and pilot bushing installed. I also have a proper new throw-out bearing.
The clutch fork thing that goes in the side of the bellhousing hole has me stumped though.

The engine is out of the car and I've forgotten how that fork is held in place, AND, should my TO bearing fit loosely in the fork??
I mean, I know the TO bearing will go against the diaphragm and the pedal rods (z-link?) will touch at the other end of the fork, but how does this fork stay in place?

I noticed a single, yup, single little hump on the neck of the TO bearing but I'm not sure if it's pertinant. Would have made more sense if there were two of them 180 degrees apart to help hold it in place.

Since the TO bearing is loose, should I use some pliers and clamp down on that overlay thing that's trying to hold it in place or is it ok?

The fork and throw out bearing will be retained in place by the fork retainer and the transmissions bearing retainer..

The fork stays in place on the ball-stud in the bellhousing. The "bump" on the TO bearing goes in the "crotch" (as I've had it described to me before :) ) of the clutch fork.

Don't want to clamp down on the spring clips that hold the TO bearing in the fork. It needs to float a little once everything is all together.

Do not attempt to slide the bearing into the clips on the fork. the frame of the fork and the springs go in the channel on the bearing. The springs keep a little presure on the bearing to keep it from chattering in the fork when the clutch is depressed. On the back of the fork there should be a forked spring that slides over the pivot ball in the bell housing. Put the fork on the bell housing and then put the bearing in the fork. Putting the hump in the crotch of the fork keeps the bearing housing from turning in the fork.

Oh, Oh, Oooh.

So, I attempted this today and noticed the "ball stud" inside the bell-housing, and how the fork has that clip in that area to slide over the ball stud. That's good. and pretty much answers my question about the fork.

This is gold right here: "Do not attempt to slide the bearing into the clips on the fork. the frame of the fork and the springs go in the channel on the bearing."
Thanks for that Jim because I certainly DID have it wrong. I had the bearing between the fork and that spring-metal piece.

I'm such a dunce. :)

I also haven't found the bellhousing torque-specs in my Chiltons nor online If anyone has that, please share!
