Not trying to be trite at all.
Ohhhhh I see. My apologies.
I'm thinking that, unless someone with one of these tells me otherwise, I'm going to go ahead and run the adjustment up until the pedal gets close to all the way up in the car - but not ALL the way. I don't want to run the risk of putting any pre-load on the throwout bearing.
No. You will need a small spring down on the clutch fork that will pull the fork so that the linkage pushes the clutch pedal to the up against the rubber stop positition. There is a chance that you are missing that rubber stop. .................................MO
Last paragraph. Hard to diagnose without being able to look at it. IF you installed a spring on the clutch fork to pull it forward and away from the throw out bearing touching the clutch "fingers" in addition to the small spring that holds your adjustment linkage together---then I would say that you have something wrong between where your linkage attaches to the pedal and where your Z bar attaches to your clutch adjuster. I don't believe that spring on the fork to pull the throw out bearing away from the clutch fingers is shown or talked about in the Centerforce directions. Evidently they don't care if it does rub.
Post #370. Brand new return spring is installed on the clutch fork, just like the FSM diagram shows. The purpose of that spring is to hold the throw out bearing off the clutch fingers, though, not to make the pedal return all the way.
OK I forgot that yours is 68? and mine is 64. There may be a difference. On mine , that spring on the fork ( not the small one that holds the clutch adjustment rod together) also holds the clutch pedal up against the rubber stop, by pushing back against all the linkage. Please let me know what you find is your problem JFMI.........................Good luck..............................MO
Got the answer right from the horses' mouth, my friend
:
Absolutely makes sense. You are going to love that clutch when you actually get it on the road. Matter of fact, you will wonder how it can possibly hold any power. .........................MOI've copied this post from another thread I've got going right now titled "Centerforce Dual Friction Clutch", in which I'm asking about a pedal return spring to take the place of the disconnected over-center spring in the car. Pasting here in case other folks see this thread instead of that one:
That's true of any "conventional" clutch, I think - there's the part of the pedal travel where the actual clutch engagement/disengagement takes place with any clutch, right?
As the clutch wears, that point of engagement moves higher in the pedal travel until you have to get under the car and make an adjustment to compensate for wear.
Folks have their preferences as to where in the pedal travel the clutch activates, but generally around halfway up or so.
That leaves the rest of the pedal travel above that clutch engagement point, where the pedal pretty much freewheels up to the stop for it.
On a conventional stock clutch, that is taken care of by the over-center spring, which pulls the pedal the rest of the way up without any movement or assistance of the actual clutch.
Well, we take the over-center spring off per Centerforce instructions when using this Dual Friction diaphragm clutch setup - leaving us with nothing to pull the clutch pedal the rest of the way up after clutch engagement.
That's what I'm asking about here - do I install a lighter spring under there just to do the "housework" of pulling the pedal the rest of the way up or do I even concern myself with it?
The conventional in me wants that pedal all the way up, both because it's what I'm used to AND it assures me that there's no undue pressure being exerted on the clutch by the pedal and linkage when it's not depressed.
Does that make sense?
By the way, this clutch feels fantastic. Half the pedal effort and it's very precise on the feel of engagement/disengagement. I think I'm gonna like it.
I am glad for that info from Centerforce as I had the same question. Now that I recall, I didn't like the pedal being part way down and so I added the other spring. But I chose to do it on the clutch fork. ..............................MOGot the answer right from the horses' mouth, my friend
Update on my clutch pedal question:
I have just gotten off the phone with Centerforce Tech Support.
They confirm that what I'm experiencing with the pedal is perfectly normal
and to be expected when removing the over-center spring as they direct.
He allayed my fears of any undue wear happening to the throwout bearing/
pressure plate because of this.
He also repeated what we already know - that the small spring down on the
clutch fork right next to the adjustment rod is what keeps the throwout bearing
off the fingers of the pressure plate and as long as that is present in place,
there's no worries of the linkage/pedal prematurely wearing clutch components.
Basically, it boils down to whether I can live with where the clutch pedal rests
once the clutch has been properly adjusted.
If not, a light spring can be cobbled up on the pedal arm to return it to the top,
against the rubber stop, without undue harm to anything, if that makes me feel
better.
Mystery solved. Centerforce knows this happens and they're not worried about it.
In fact, when I asked why it wasn't mentioned in their instructions, he basically said they thought that this issue may be viewed negatively by potential customers and
would harm sales, so they just omitted it.
Well, at least they're honest.
Unfortunately, that won't do any good on mine. Any added spring would have to be installed somewhere from the clutch rod that pokes through the firewall up to the pedal arm.
