HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Lighten clutch pedal feel?

I adjusted mine until the pedal had a smooth even feel to it. If there is too much pre load on the pedal it will feel like there is a break point where the pedal initially has resistance, hits the break point and then there is no resistance. I did measure it after I found the diagram posted above and it was about 55mm.

Yes, the stock 944 clutch MC is quite soft with the stock 944 PP. However, increasing CMC bore size along with HD aftermarket PPs = "clutch foot" after a few miles of traffic.

Stock pedal feel would be great! With the Spec stage 2, it's FAR heavier than stock, that's why I want to get the return spring back in place and see how it feels...

Excellent pic, thanks! My complete spring assembly is missing.

Hey Arthropraxis, I measured mine, and it is also about 55mm. My setup is a Wilwood clutch M/C, RH pressure plate and whatever throwout bearing RH put in the bellhousing. I experienced the same thing, had to adjust until it was smooth. Feels good to me!

Items on the clutch pedal arm (from top of picture): Nylon bushing, shaft eye, washer, circlip. At the far end of the spring is a nylon cap with two ears that rides on indentations in the body.
Hi Mike, all, I notice on my just-purchased clutch pedal assist spring assembly that there is a hole through the shaft/push-rod on the nylon cap end of the rod. Is something supposed to to through that hole, maybe to hold the spring assembly in place? Or is the spring assembly merely held in place on the rod by the force of the compression of the spring itself?

Well the more I look at if the more it doesn't seem likely that there's a pin or anything that goes through that hole.

Also, as the ends of the spring are not attatched to fixed points they won't ever be under tension, so the spring is only to assist when you step on the pedal, it can't help the pedal return from the floor.

Well, it's on. Huge difference. Maybe I won't be swapping out the clutch for a lighter model after all...

Nothing goes in that hole, I think it is there to put something in to hold the spring in place for servicing the clutch pedal. Sounds like this worked out for you!

Clutch spring

Post  fliermike45 on Thu Oct 13, 2011 6:42 pm

If you look at the excerpt from the Porsche manual on page 2 of this thread and read the line at the bottom, it explains the use of that hole.

Well, there ya go! Instead of using tie wraps to keep the spring compressed when I mounted the assembly, I could have just pushed a cotter pin through hole. Sure would have been easier!

And...just realized that I had backed off the adjusting nut when mounting the assembly and forgot to tighten that nut back up. Doing so will reduce pedal effort even more...

Now that you have that back together, pay close attention over the next few days to how the clutch acts and feels going through the gears. Listen /feel for gear noise and engagement. I remove these on the cars that I convert because I have had the spring push the pedal down just enough that the master bleeds of just a little and I do not full disengagement. On my personal car, when it was running, the pedal would be a 1/4 to 1/2" down before I even started driving. I removed the spring and it never did it again. I don't know why it did that and really cannot explain it, but it happened and the fix was spring removal.

Spring

Post  fliermike45 on Fri Oct 14, 2011 6:02 am

Acorad, for some reason I could not compress the spring far enough using the hole.

That's why I used tie wraps.

That's good news! Exactly what I want. I definitely don't have a problem with pedal return. Eric, have you finished moving yet? I'd love to get the spring setup now that it sounds like it'll do what I want!

Remember , it's not a return assist, It helps on the down force....... I will be completely moved by Monday.

Yep, that's what I'm looking for. The clutch has more than enough pressure to pop up on it's own, it's just very heavy pushing it down...

If you read my previous post closely , I have found the spring to slowly over time push the clutch down.

Hey Admin, do you have the return spring on the clutch pedal like the brake pedal? I'm wondering if this would keep the pedal from moving down like you have experienced. I haven't had mine running long enough to gain any experience on this topic yet, other than the clutch feels good, but stiffer than the 944s original one. Which to me is a good thing!

I did read that, but I'd like to have the spring installed anyways. I can always remove it if it becomes an issue, but the heavy clutch feel is more than I care to deal with...

So I cranked up the compression on the assist spring today, just for kicks, and it's almost too easy now. fwiw, the engagement point of the clutch has moved much closer to the floor, no idea how that will play out over time.

Closer to the floor means it already disengaging the the clutch, Just as I wrote in my previous post. That means soon a slipping clutch and then slight gear grinding noise on most gears. Then near impossible to get it in reverse.

Thanks Admin, I'll back the adjusting nut off some and see how it does.

Just got one of these in the mail yesterday. Hopefully get it in the car today and see what sort of difference it makes.

I take it I assemble it out of the car, use a pin to hold it all together, then just put it into place from above after moving the fusebox out of the way? Then pop the C clip in place, adjust it to 55mm and call it a day?
