Installed a new clutch in my 360 4-speed. Found out my under dash, I believed it's called a over center spring, that connects to the clutch pedal does not work with Diaphram style clutch. What is the best spring setup for this situation?
none. You don't need one at all with a diaphragm style clutch.
To combat that spinning R-bearing situation, I installed a spring on the fork,under the car, to pull it back and park it. It seemed easier to me .
And when it pulls down at the bottom, on a diaphragm thats bad, because the diaphragm barely has enough power to return itself at idle. But once the flyweights move out(around 3000plus rpm),Theres a real good chance the diaphragm cannot return it, and then the pedal stays on the floor.You better have a rev limiter.
It is a good idea to have a light spring on it. Without a spring the weight of the pedal will always sit on the linkage, and consequently the throw out bearing will always be in contact with the clutch fingers and spinning, causing an early failure of the throw out bearing. I used a modified jack hold down spring from the trunk. It worked great.
Same reason you should never ride the clutch or drive along with your foot resting on the pedal, and also why the original over centers....it pulls up at the top, and down at the bottom.
Yep, the spring was standard from the factory even with the OC spring; it is called an 'anti-rattle' or 'fork return' spring. (BTW, the OC spring may not actually pull the pedal all the way up, as it's force can be fully released before the pedal is at its full up position.) And even with the pedal all the way up, the pushrod to the fork will still be loose, and the fork prongs and TO bearing are free to move forward. So the anti-rattle/fork return spring is there to pull the fork and TO bearing back, and helps insure that the pedal is fully up too.There IS a light spring on it. There's a spring on the clutch adjuster that pulls the fork back, and that should be more than strong enough to keep the throwout bearing from being in contact with the diaphragm. It is on mine.
Look around for the factory style spring, maybe try Brewers or Passon.
Ok thanks. My dad was researching and was finding contradicting info. So say remove while others say it stays. For now I just put a small spacer under the carpet. working great so far. Its all about adapting sometimes right. LOL.
Yes, I have the small spring on the clutch fork. Anyone know if any damage will occur if I leave the over center spring for a little while and just make sure I pull the clutch up with my foot. Just want to drive down the street a few times carefully before I remove the oc spring.
