A subject near to my heart. "Dual Friction". *shudder*
I have an entire long thread on here about my own installation of one of these. It worked out in the end, but you'll
find out you need to re-think some of what you thought you know about clutches after you get yours installed.
These guys are all giving you excellent advice, for starters.
1. Yes, you will need to remove the over-center spring under the dash. If you don't, the clutch will pick the worst time
(usually during some spirited gear banging) to go to the floor and stay there until you bring the car to a total stop.
2. No, there aren't any actual step by step instructions from CenterForce for these.
Trust me, been on the phone with them more than once. It installs like any other clutch, with a few caveats.
3. It is
critical on these to get the adjustment correct once installed. Visually verify that the throwout bearing is not
resting/in contact with the clutch diaphragm when the clutch pedal is released.
This is
very important. CenterForce says 1/4" gap there is recommended. My FSM says 5/16". Just make sure there is a gap there.
The small spring that connects between the clutch adjuster and a little hole on the bellhousing is what maintains that small gap.
Make sure it's installed and in good shape (or even replace it).
4. The clutch pedal is
not likely going to rest at the top of its' travel once you've got everything installed.
The over-center spring you removed under the dash also serves to hold the pedal all the way up to the pedal stop rubber bumper
when the clutch is released - and that's now removed, right?
5. Adjust the clutch so that it operates/engages around 1/3-1/2 way up in travel and you'll find the required gap between throwout
and diaphragm is pretty close if all the other linkage is in good shape. There isn't much take-up on these clutches, since all you're
overcoming when depressing the clutch pedal is that small gap between throwout bearing and diaphragm.
6. If you get everything set up correctly, you're going to love this dang clutch once you get used to it.
Much lower pedal pressure needed to operate it. It does act like any other diaphragm type with a sort of "on-off" toggle switch
sort of feel, too.
You'll wonder how such a light feeling clutch can actually handle the torque of our big ol' V-8s.
Good luck!
