911 sc 80 targa clutch adjustment

[dutchconnection]

Adjusted the clutch according to the specs but I can only get 19 mm of travel instead of the 25mm. The bumper on the floor board is all the way up but it’s not enough. Any suggestions why I don’t have the required pedal stroke?

Can you move the clutch pedal toward the seat when it’s in it’s resting position? Could the clutch pivot arm be mounted on the wrong spine? Do you get full disengagement of the pressure plate when the pedal is depressed?

The pedal is all the way back. The reason why is started to look into this is because the clutch is still engaged with the pedal all the way down. Measuring 19 mm of travel instead of the 25 mm by design.

You may have a cracked release bearing fork. Bob

If the release bearing fork is cracked I should still have enough travel. I think there is something with the pedal cluster that doesn’t give me the full cable travel.

Where you at in Michigan?

You may have an issue with the fork (there have been many - a - cracked in these circles); OR you may have an issue with the pedal cluster. Perhaps a picture or two of the pivot point of the clutch pedal is in order here (?).

I’m in Ortonville north of Detroit. I will look at the pivot point tomorrow when I have some time.

When I had a Carrera, I was never able to get the full 25mm travel although it was enough to get the job done. I think the reason why you do not get the full travel is ...

1. You did not adjust the Bowden tube tight enough.
2. There is not enough tension in the cable as it has come detached from the mounting point in the tunnel.

So as you push the pedal, the effort by the cable is spent tensioning the cable housing instead of pulling the cable through.

In my case, I had to find a way to replace the welding points for the cable to stay put inside the tunnel, and adjust the Bowden tube to add more curve to the tube, and then take out the free play as much as possible. Never was able to get the full 25mm, but close enough to work.

Problem found after I removed the pedal cluster. The arm, clevis pin and bushing are completely worn out.

That will be a fun project for the winter while she's in storage!

For those *interested*

...I have seen this car that the OP is working on. It is *very* well sorted and very nicely cared for. I am sure that this will be another one of those projects that will go quickly, and you will be back in action before you know it.

Thanks for the nice words. It’s not a show car but a daily driver when it doesn’t rain with 160,000 + miles on it.
