I found only stock "pull type" clutch parts that site.

I mean push type...

Do you know the "branding" of the clutch? Snapshots?

You need an assembly which would be both unless you've a bearing only failure.

Clutch is centerforce DF612909, normal big blocks clutch..
Fltwheel is 168th
Bellhousing Quicktime RM-6039

But what is functional bearing...

OK I see a couple posts for information nearly two years old and youre needing something with an assembled height of 1 1/8". Is that correct or just an estimate. This is behind a Chev BB? Not an LS engine?

It looks like the part number of the ZF transmission might help here with bearing selection BUT I believe that for any install the guide tube might likely need to be modified. Can you post your ZF part number or at least the length of the input shaft tip to transmission case. It's either 159.5mm or 190.5mm. You've confirmed fit of trans to engine with the clutch and the QuickTime installed? I'm very confident of the 159.5 but thought I'd ask. Let's also get the OD of the guide tube to confirm for bearing 1.305" (33.147mm) or 1.375" (34.925mm).

Let's use this McLeod pdf for some dimensions: http://www.mcleodracing.com/info/download.asp?id=5487#

I could email it if you've a connection problem. PM me your email address. I believe I've got the choice determined.

Hello
And thanks for advice.
My combo is this like...
SBC gen1 with 168th flywheel. Clutch is centerforce DF612909,
bearing is southwest 650-620(height 44mm)
bellhousing RM-6039 and 10mm spacer between bellhouse/tranny(because 650-620 bearing is too height)
I think this bearing is something wrong, everytime when car stay about week or more, after that i have to bleeding system(ny fluids) Once I have fixed it and install new o-ring seals, but it doesnt help.
Now I looking for better hydraulic bearing which is so slim that I dont need spacer between bellhouse/tranny.
With stock pedal cylinder clutch is little heavy to use(stroke limit) I.m interesting too good pedal cylinder...
Tks once again, I send pm...

I agree with the plan of scrapping the 10mm spacer and to determine the master/pedal etc it would be good to know what it's installed in. I'm guessing a C3 of some sort. In you PM include your email. I think that would be easier. For the dimensions you realize the transmission will need to be removed from the car or it will be a guess. The PDF should have been very informational! I'll watch for your PM.

I understand why the SWS 650-620 will NOT likely work. That is for some early applications with smaller clutch that required a bearing and support that's 1.75 or so tall.
