409 throw out bearing ?

[dirtydave]

i am putting together a 340 hp 63 409 4 speed car,i have the 553 alum.bell housing,a 14 inch 168 tooth flywheel,and ready to order a clutch set up.what bearing do i need(long or short?)for this set up?i will be using the clutch fork for the 409.

Dave, Most companies now supply the throwout bearing with the clutch and pressure plate. You failed to mention if you are ordering diaphram clutch or B&B (3 finger) clutch. I believe the diaphram uses short bearing and 3 finger clutch uses long bearing.

Bearing

I was thinking, the long bearing for the diaphragm, the short bearing for the B & B style. The B & B stands out farther, so would need a shorter bearing. That's the way I remember it. Doesn't mean I'm right, though.

OOOps! Too important an issue to not be sure. I certainly dont trust my memory. Can someone post a " Im sure" answer?

Throwout Bearing

I'm not trying to contradict anyone, but if your gonna use a borg/beck pressure plate, use the long throwout bearing. The diaphragm uses a short bearing. I made this mistake a long time ago. Using the longer bearing with a diaphragm pressure plate causes the bearing to wear out much too soon. Also it never shuts up. I don't think it disengages fully from the diaphragm fingers. Skip

clutch

Dave, I used an 11in. Zoom diaphram with 10/1/2 in disc. in both my SS/C car and my D/S. best set up I ever had...BTW used short brg. Got it ay US nats from VP of Zoom at the time.

Thanks Bob, good advice. For those who would buy a 11 in. clutch and pressure plate, to replace for improvment, be sure your flywheel will accept 11 in unit. If memory serves me, the 11 in. wont bolt up to a flywheel that has 10 in clutch. Dont remember about the 10 1/2 unit.
