Clutch pedal position suddenly changed after a snapping noise.

[Oyagi]

Well, crawled around under the dash and found the other half wedged in there. My supplier cannot get me a replacement part in time for me to enjoy the rest of the driving season up here in Canada so I’m taking this thing to a buddy who builds hot rods to see if he can weld this thing back together for me. It’s not ideal but hopefully will allow me to use the 930 while I source the parts for a full refresh of the pedal cluster this winter. I’ll report back.

I don't think that is weldable, you will destroy the spring temper. You need a new one.

Can you purchase from Pelican or somewhere else?

Just drive without it. For the short duration that you'll be driving it you're not going to hurt the clutch cable. I think I went without mine for half a year.

It'll be a little harder to shift, and you'll feel it holding the clutch down for a few seconds, but the weight of the pedal tugging on the cable (which is what the spring prevents) is really not going to hurt it.

I stopped in the Porsche dealer in Sewickley PA yesterday and asked about the spring. They were able to find the part number but said the spring has been discontinued for several years.

I used the helper spring for a Carrera - seems to work fine.

I had to make sure it was oriented specifically to avoid binding against the pedal as I recall. Works though. Hard to install due to the tension of the spring...

Thanks. I'll give this one a try.

BTW, at the Porsche dealer, I saw several new 911's, new 911 turbo, 918, Cayman, and Boxters. None had a clutch pedal...

Update:


Success! My buddy welded the snapped spring back together (and we bench tested the strength by applying 200lbs weight to it!) and after some struggling I got it back on. Cost was a six pack of Molson.


I did the suggested trick and shoved some washers into the coils to stretch the length out a bit to help with installing it.

When your driving season is over send your pedal box to Bruce Stone who will rebuild it for you. Bruce has rebuilt three for me.

Why send it out? The hard part is removing it, rebuilding it is easy. Does Bruce do cleaning and powder coating as well?

I have a similar situation with a weird twist. Car's been in storage and I took it out a couple weeks ago to put it back on the road. Yesterday clutch pedal did the 1 inch drop. I'm looking to replace the pedal board anyway so I pulled it off today to clean and check the pedal cluster. I rebuilt the pedal cluster just before I put the car in storage. The clutch spring is not broken, it seems to be stretched????? everything works correctly, pedals push easily, no excess play anywhere etc.... just the spring is seems to me stretched slightly. I've never seen or heard of this happening. Glad nothing else is wrong and I can replace it easily just really strange

yes you can, Pelican carries 3 types I believe

Careful which one you choose the version I used lost tension\stretched as a result the pedal is depressed about 1 inch as if the spring is broken, although it isn't. Very weird, I've never seen or heard this happen before. Notice the space between each wrap of the spring? This is with no tension on the spring or without the pedal being depressed at all. It's at full rest and as a result the pedal does not return fully!!!!!! I now need to replace it with a different type spring.

I might check if something else is in a bind or out of adjustment preventing the pedal from coming all of the way up. The clutch itself should be pushing that pedal most of the way back up, and the spring just holds the pedal at the top spot.

David,

The spring is clearly stretched and you can see the space between each coil of the spring compared to the other photos in this thread. That is not normal and the spring coils should be tight against each other. There is nothing else binding in the pedal cluster and the pic I show of the stretch spring is with the pedal all the way up (held in place by my hand ). As soon as I let go of the pedal the spring pushes the pedal down about 1 to 2 inches. The fix is a new spring which is on order and I'm just waiting for it to arrive.

I guess it looks of a slightly thinner material than I remember mine being, but it's supposed to be in the stretched position with the pedal up. When the pedal is down it's compressed.

The geometry of the pedal action is such that the pedal stretches a bit when you start pressing the pedal, and then starts compressing as you push the pedal down further--it both holds the spring up top and helps you push it down. In other words the spring is compressed with the pedal all the way down, 95% stretched with the pedal all the way up, and 100% stretched when the pedal is pressed in just a little bit. The spring should be pulling the pedal up so much that when you pull the pedal up it stays there until you push it down.

Are you getting an action like something in this video?

I might try lubricating the whole thing, the spring doesn't have a ton of leverage for that last little bit and it might have just stiffened up in storage.
